MEMS Digital Inclinometer System with Android Instruction Manual

1 INTRODUCTION The RST MEMS Digital Inclinometer System represents a breakthrough in inclinometer system , providing unprecedented accuracy, efficiency and ease of use. The system is comprised of a Digital Inclinometer Probe, cable system, reel with battery power, and an Ultra-Rugged Field PC running Mobile Microsoft Windows™ that functions as a readout, analysis, and data storage device. Wireless communication between the inclinometer control reel and the Ultra-Rugged Field PC ensures ease of use and reliability, by removing two weaknesses inherent in conventional analog inclinometer systems. By removing the physical connection between the inclinometer control cable and the readout instrument there is no concern with fragile connectors, cable related failure and related reliability problems. The Achilles heel of any inclinometer control cable reel is the slip ring required to maintain electrical contact as the reel revolves. As the RST system is wireless from the control cable to the readout, a slip ring is not required, and there are no associated electrical continuity problems. The RST digital inclinometer probe incorporates cutting edge MEMS (Micro Electro- Mechanical Systems) technology providing high precision and durability. A highly accurate survey of the inclinometer casing is used to establish the initial position of the casing. Any subsequent deviations in the casing from this initial value (i.e. baseline reading) represent changes occurring in the subsurface. The RST MEMS Digital Inclinometer System can accurately measure the rate, depth, and magnitude of these deviations. The information included in this manual outlines the use and care of the RST MEMS Digital Inclinometer System. It provides examples of how to take readings and interpret the data. For more information on the installation of inclinometer casing, and other related issues, please contact RST Instruments Ltd. Note Proper care and maintenance of the MEMS Digital Inclinometer System will greatly extend the life of the instrument and accuracy of the readings. Please take the time to read this manual thoroughly. If any questions arise, do not hesitate to contact RST Instruments Ltd. Proper maintenance of the probe after each use is outlined in Section

X12X.

2 DIGITAL PROBE In general terms, the new Digital Probe resembles that of the traditional analog probes sold by RST. The RST Digital Inclinometer has the smallest package available for a given spacing, with the best ability to track deformed casings. This means that the Digital Probe can handle greater bends in the casing without becoming stuck. The RST metric probe can negotiate a radius of 1.88m (74”) in 70mm (2.75”) OD inclinometer casing. The RST Digital Inclinometer will thus continue to provide readings past the limit for other probes on the

market (see XFigure 2X).

Figure 2 – Digital Probe Sizing The connectors, , and wheel carriages are the most precise and durable in the . The probe wheels are made of high grade hardened and heat-treated stainless steel. These are extremely durable and the most robust on the market. The digital probe also incorporates shear pins on the wheel assemblies. In the event that the probe gets stuck in the inclinometer casing, a force of approximately 300 lbs is required to shear the shear pin. No damage to the probe or cable will result. Please contact RST Instruments Ltd. for further instructions on retrieval of a probe that is stuck downhole, and the replacement of the probe shear pins.

DUMMY PROBE Dummy inclinometer probes are available for purchase from RST for testing purposes in a borehole. RST encourages customers to try the new digital dummy probe in existing holes where the competitor’s probes do not work. If it is found that the dummy probe passes through all areas of the casing, the RST MEMS Digital Inclinometer System will function. Therefore, the existing hole will still be viable, and a new hole will not need to be drilled. The RST dummy probe has the exact same weight and dimensions as the standard probe. A ring is provided in place of the connector which allows the dummy probe to be lowered by a rope. For further information on purchasing a RST Dummy Probe, please contact RST Instruments Ltd. SIGN CONVENTION AND MEASURED DEVIATION The Digital Inclinometer Probe houses two MEMS accelerometers, which measure tilt in two axes. Proper installation of the inclinometer casing attempts to align one set of grooves in line with the axis of expected movement. This is called the A axis. The perpendicular set of grooves is the B axis. When an inclinometer casing is surveyed for the first time (i.e. baseline readings), it is necessary to select a fixed direction reference for the probe so that each time a survey is repeated, the probe will always have the same orientation in the casing. For example, in an area suspected of activity, the first set of readings would be taken by placing the upper wheels of the probe in the casing groove closest aligned to the

downslope direction. XFigure 3X illustrates an inclinometer casing installed with a groove orientation in the general downslope direction. In practice, it is often difficult to achieve exact orientation of grooves relative to some predetermined direction. The groove closest to the anticipated movement direction is usually chosen as the main reference direction. It is recommended that this direction (A+) be marked on the casing itself to ensure surveys are performed in the same manner each time. The azimuth of this groove direction can be measured in a clockwise direction from the main reference direction (A+). All subsequent measured inclinometer movements would be referred to this direction. Readings taken from the inclinometer probe (see Section 2.3) are actually deviations from the vertical over the distance between the upper and lower wheels (see Figure 4), calculated as: D = L × sine(α) Where: D = Deviation, e.g. lateral displacement in the direction of the axis of measurement L = inclinometer probe length (typically 0.5 m for a metric probe or 2 ft for an imperial probe, as defined in Section 10). α = inclination angle of probe from vertical axis

ICM0099A 4

Figure 3 – Probe Orientation The RST Digital Inclinometer System uses the industry standard sign convention, where tilt in the direction of the upper wheels results in a positive deviation and tilt in the direction of

the lower wheels results in a negative deviation ( XFigure 4X).

TAKING READINGS 1. Upon arrival at the site, remove the protective caps from the casing, the probe, and the control cable. If possible, flush the borehole with clean water prior to taking measurements. Groundwater with high salinity or suspended particulate content can damage the bearings in the probe wheels with repeated use. 2. Attach the probe to the reel by aligning the keyways and threading the connector onto the probe. Ensure the connector is lubricated, clean, and free of debris prior to making the connection. Take care to turn only the threaded ring, not the cable itself. Do not over tighten the connector; a hand tight connection is sufficient. Warning Handle the inclinometer probe very carefully as the accelerometers are very susceptible to shock. 3. Once connected, turn on the power to the reel. This energizes the MEMS accelerometers and makes them less susceptible to shock. 4. Insert the probe into the borehole, aligning the upper wheel in the direction of the A+

axis (see Section X2.2X). 5. Lower the probe to the desired depth slowly and as smoothly as possible. Be extremely careful not to bounce the probe off the bottom of the hole. Any shock to the probe may damage the probe electronics and affect its calibration.

ICM0099A 7

6. Once the probe is at the desired depth, place the cable grip on the top of the casing and hang the cable by the aluminum crimps. The objective is placement repeatability within 5mm (0.25 inch). This is extremely important to ensure accurate and repeatable results. Warning Do not drop the cable aluminum crimps onto the cable grip. The cable has very little stretch, especially near the top of hole, and the impact on the cable crimps may “hammer” them out of position or break the cable. This effect has been demonstrated for drops as little at 70 mm.

7. The probe will begin profiling the borehole from the bottom of the borehole. After each respective measurement has stabilized and a recording has been taken, pull the probe upwards to the next desired measurement depth. If you accidentally pull the probe too far, lower the probe back down to the previous measurement depth, and then pull it back to the next intended measurement depth. This procedure ensures that the readings will remain consistent. For maximum measurement repeatability, keep the cable as clean as possible during this process. If possible, a tarp or basket can be useful to avoid placing the cable directly on the ground.

Warning Never tightly coil or sharply bend the cable during this process, as this can cause permanent coiling or twisting of the cable which can impact the spacing of the aluminum crimps and measurement repeatability. It is recommended to lay the cable in a “figure-8” or “spaghetti bowl” pattern as follows: a. “Figure-8” Cable Management: As the probe is brought up-hole, lay the excess cable on a clean surface in alternating loops to form a figure-8 pattern. The loops of the figure-8 should be approximately the size of the cable reel diameter. Once the survey is complete, flip over the bundled figure-8 of cable for easy spooling back onto the reel. b. “Spaghetti Bowl” Cable Management: As the probe is brought up-hole, allow the cable to freely coil as it is laid on a clean surface. Do not attempt to twist or coil the cable, as this can deform the cable with repeated use.

8. Allow the readings to stabilize at each location. Reading stability can be gauged by both the noise bar and the standard deviation, which are displayed on the Readings List (Section 4.3.7). 9. Once the readings have stabilized, press the Accept button and move the probe to the next interval as prompted by the software. 10. Repeat Steps 7-9 until the probe reaches the top of the borehole. The App will then prompt you to turn the probe 180 degrees and repeat the survey, this time in the A- direction (i.e. with the lower probe wheels in the A+ groove).

Warning When the probe has reached the top of the casing, avoid allowing the wheel assemblies to snap out of the casing. As the wheels reach the top, grasp them with your hand and release the wheel assembly slowly until it reaches the stops. Failure to do so will damage the shear pin and subject the MEMS accelerometers to sudden shock, which can damage them and affect the calibration of the probe.

11. Prior to lowering the probe for the second pass, remove the cable grip to avoid accidentally catching the aluminum crimps on the cable grip (this will impact load the crimps, cable, and probe). Once the probe is at the bottom of the borehole, replace the cable grip and position the probe for the deepest reading. 12. Repeat Steps 7-9 to take a second pass of readings in the A- direction. During this second pass, checksum data will be displayed underneath each reading. Ensure that these remain small and consistent; however, checksums can vary due to different site conditions. Large checksums can indicate errors in probe positioning or fouling of the probe. Expect checksums to be slightly larger when the probe encounters an expansion coupling in the casing (if applicable). Refer to Section 6 for further detail on checksums. 13. The RST MEMS Digital Inclinometer has the ability to perform data reduction in the

field, please refer to Section X4.2.8X for information on viewing and validating the data. 14. Upon completion of the survey, close the inclinometer app, turn off the power to the reel, and disconnect the probe. Wipe off the probe and cable. If possible, rinse the probe and cable with fresh water. Replace end caps on the cable and probe. Replace the protective cap on the casing. 15. Upon returning to the office, clean the instrument and reel once more to remove any moisture from the instruments and the case. Recharge the batteries for the Reel and the Android data collection device. Please refer to Section 8 for proper care and maintenance of the system. 16. If required, transfer the collected data files via email or file transfer.

3 INCLINOMETER CABLE AND REEL The RST MEMS Digital Inclinometer System comes with a durable lightweight reel that is easy to handle. Since only a pair of conductors is needed in the cable, the weight and dimensions of the cable are drastically reduced as compared to a traditional analog cable. The reel is battery powered and houses the electronics used for wireless communication. An important part to any inclinometer casing survey is the repeatability of the depth measurements. It is extremely important that measurements be consistently within 5mm (0.25”) of one another between subsequent surveys. To facilitate accurate repeatability, two aluminum cable grips are provided with the system, for 70mm (2.75”) and 85mm (3.34”) OD casing respectively. The cable grips provide a solid reference for the cable crimps to sit in. The result is that operator error is reduced, checksums will be smaller and surveys more accurate. The thin, strong cable contains a Kevlar® strength member, allowing a long length of cable to fit on a small reel with no stretch. The aluminum sleeved measure marks are precision swaged to the cable and are not subject to tearing when handling. The measure marks are spaced at 0.5 metre or 2 feet intervals. The cable is marked with a red measure mark and a label every 5 metres or 10 feet, depending on whether the metric or imperial system is being used. The urethane jacket is highly abrasion resistant and maintains flexibility at low temperatures. It is good practice to avoid running the cable over sharp edges and to periodically clean it with a soft clean cloth. Be sure to keep the protective cap on the connector whenever the probe is not in use and avoid dropping or banging the cable end. Always keep the connectors and threads clean by rinsing them with water and be sure to lubricate frequently. Exercise care when connecting and removing the cable from the probe; make sure to only turn the connector ring, not the entire cable.

The following instructions are for reels with serial numbers of 2500 or higher. The battery will need to be recharged using the provided charger. The battery port may be accessed by unscrewing the cap on the outside of the reel. Refer to Figure 7 for the location of the battery cap.

Figure 7 – Unscrewing the Battery Cap Unscrew the battery cap by turning it counter clockwise. The charger will plug into the port and begin charging the battery. Replace and tighten the cap when the charger is not in use to ensure debris does not enter the battery port. WIRELESS COMMUNICATION Turn on the power to the reel by pressing the button located to the left of the battery housing on the Reel Hub (Figure 7). A solid green light indicates the reel has been powered on. After turning on the power to the reel, it automatically broadcasts its device name and will continue to broadcast for up to 5 minutes. During this 5-minute window, the Digital Inclinometer app must establish a Bluetooth connection with the reel. If the Reel Hub is unable to connect to the Digital Inclinometer app, the Reel Hub powers down to reduce battery consumption.

The Reel Hub reset button is equipped with a green light status indicator, The status light indicates that the Reel is in one of the following three states: • Off – the Reel Hub is powered off. • On – the Reel Hub is powered up, but not connected to the Digital Inclinometer app. • Blinking at 1-second intervals – the Reel Hub is connected to the Digital Inclinometer app.

4 ANDROID DIGITAL INCLINOMETER APP The RST MEMS Digital Inclinometer System app runs on most Android devices running Android 5.1 and higher. The Android device functions as a readout and data storage device. Data reduction can be performed on site as soon as the survey is complete. The app is equipped with data visualization features to qualify data accuracy. REQUIREMENTS The Digital Inclinometer app can run on Android device with Android 5.1 and higher. The device should be Google Mobile Services certified and be pre-installed with apps such as Google Play and Google Gmail. The Android device must be equipped with a Bluetooth classic capability to support wireless connectivity with the legacy and latest generation inclinometer systems. Other wireless networking capabilities such as Wi-Fi and Cellular are recommended for remotely updating data collection files over email services. DEVICE RECOMMENDATIONS The process of collecting data at the borehole is a demanding task. The device is often subjected to harsh environmental and field conditions. Due to these considerations, RST recommends only rugged Android devices that can withstand the daily rigours encountered in the harshest environment, such as the Samsung Galaxy Active 2, the Juniper Mesa3, and Juniper CP3 smartphone/tablets.

This manual details the user experience for the Digital Inclinometer app, version 1.1.0 and higher.

4.3.2 ANDROID SETTINGS PRE-REQUISITES The Digital Inclinometer app requires several custom settings to maximize the user experience. The following configurations should be customized to access the services: • Internet Access – internet access via Wi-Fi, cellular, or both, is required to allow the app to email collected borehole data to a recipient. Email is one of the available mechanisms to transfer collected borehole data from the device to another computer. • Voice Call or Text Messaging – the Digital Inclinometer app has capability to call a contact person. If this feature is required, an activated voice SIM card must be inserted and configured. • Gmail Account Setup on the Device – a Google Gmail account on the device is recommended. The Digital Inclinometer app uses the Gmail account on the device to send collected borehole data to an email recipient. • Font Size and Screen Zoom Settings – the default font size and screen zoom on the device are two settings that affects the appearance and layout of the app. Selecting an inappropriate font size and zoom setting may result in truncation of words and excessive word wrap. To avoid these problems, adjust the Android font size and style accordingly to a desirable setting. The font size and zoom setting are configurations available in the Settings→Display category. It is recommended that the user configure the device with the smallest font size and zoom setting as an initial setting, increasing the font size and zoom setting incrementally to the desired appearance. • Screen Timeout – the screen timeout should be set to a large timeout value, such as 30 minutes. The timeout specifies the time before the devices enters sleep mode.

4.3.6 VIEW BOREHOLE LIST The View Borehole List is displayed when the user selects a particular site from the View Site List screen. The View Borehole List displays a listing of the available boreholes sorted based on the borehole creation date. Each borehole shows the borehole name, and the depth of the borehole. Tap on a desired borehole to view the borehole readings associated with the selected borehole. The user may also tap the More icon to call the contact person’s phone number or edit the site information. The user may also tap the + NEW BOREHOLE button to create a new borehole. A borehole is created by entering the following information: • Borehole Name (Mandatory) – Name of the borehole • Depth – Depth of the borehole’s lowest reading. The depth will always be in increments of 0.5 meters or 2.0 ft. • Top Depth – Depth of the borehole’s top reading. This is normally set to 0.5 meters or 2.0 ft. • Unit – Measurement is taken in meters or feet based and must match the probe’s units. • Export Format – The collected reading file may be supported in two industry formats. The two formats are: ▪ Digital Inclinometer (*.csv) format: this type of file can be imported into Inclinalysis™ and Microsoft Excel. ▪ RPP Format (*.rpp): this type of file can be imported into Inclinalysis™, DigiPro and Slope Indicator’s software including DMM for Windows. GTilt and GTilt Plus software also has the ability to import *.rpp file formats. A sample borehole list is shown in Figure 15.

4.3.7 VIEW READINGS LIST The View Readings List is displayed when the user selects a particular borehole from the View Borehole List screen. The View Reading List displays a listing of readings taken from the borehole sorted based on the borehole reading timestamp. Each reading shows the reading completion date and time. If the reading were incomplete, the reading status displays “Incomplete”. The user may resume taking readings from an incomplete reading. The user may also tap the edit icon to edit the borehole information. The user may tap the Graphs tab to view the combined graphs of readings from the borehole. A description of the combined graphing capability is detailed in Section 4.3.8. The user may tap on a desired reading to view borehole readings taken on a specific date or resume taking readings from a previously incomplete session. The user may also tap the + ADD READINGS button to add a new reading. A description of the Add Readings feature is detailed in Section 4.3.9. A sample reading list is shown in Figure 16.

Figure 16 – Sample reading list and comparison graph

4.3.8 VIEW READINGS LIST - COMPARISON GRAPH The Digital Inclinometer system has been developed to accurately measure the lateral movement of earthworks and structures. The probe is passed through the inclinometer casing and a reading is taken every 0.5m or 2ft. When the probe is at rest, servo-accelerometers sense the inclination of the access tube in two planes. This inclination is displayed in terms of angular DEVIATION, which is recorded at that particular depth. A+ = Face A+ deviation A- = Face A- deviation B+ = Face B+ deviation B- = Face B- deviation

The View Readings Comparison Graph feature combines the multiple readings from one borehole and compares the result against a specific base reading. Typically, a base file is chosen (typically in the form of an initial reading) and kept the same throughout the life of the inclinometer hole in order to quantify any lateral displacement that occurred. The comparison

ICM0099A 21

MEMS Digital Inclinometer System with Android Instruction Manual

graphing feature allow the user to analyze results at the borehole and take appropriate actions based on the collected results. To utilize the comparison graphing feature, the user must first configure the desired data set to review. The user must select the Base reading and the Comparison reading data sets. Step 1 - Select the base reading Tap the configuration icon to select the graph setting. Then tap the “Base reading” region to list the possible base readings to choose. Select the desired base reading date as the base or reference reading. This is shown in Figure 17.

Figure 17 – Select the base reading

Step 2 - Select the comparison reading(s) Tap the configuration icon to select the graph setting. Then tap the “Show graphs for” region to select or de-select the comparison readings. A listing of the historical readings are displayed in chronological order. Select or de-select the desired readings to compare against the base reading. This is shown in Figure 18.

Figure 18 – Select the comparison reading(s)

ICM0099A 22

MEMS Digital Inclinometer System with Android Instruction Manual

Step 3 - Select the desired graphs Once the desired data set has been selected, the Digital Inclinometer app may plot 5 different types of comparison graphs for either Axis A or Axis B. The 5 comparison graphs are: • Checksum • Mean Deviation • Absolute Position • Incremental Displacement • Cumulative Displacement Checksum Checksum in A+/A- plane = A+ plus A- Checksum in B+/B- plane = B+ plus B- Checksum should be reasonably constant and of small magnitude; large and inconsistent Checksums may indicate that a problem exists. However, the consistency of checksums from survey to survey is more important than the actual value of the checksums. Checksum data should be monitored during the survey as a check on data integrity. Note that high checksums can be expected if a settlement coupling has been encountered, a checksum of the order of (+0.0045m and -0.0035m) or (+0.0147ft and –0.0114ft) would be reasonable at consecutive depths/couplings. Mean Deviation A+/A- mean deviation in the A+/A- plane = (A+ minus A-)/2 B+/B- mean deviation in the B+/B- plane = (B+ minus B-)/2 This represents the mean deviation at each depth. Absolute Position An absolute position value at a particular depth is the summation of mean deviations, starting from the bottom up to that particular depth. The Absolute Position is the profile of the access tube with respect to the vertical axis in a given plane. The Absolute Position can also be calculated from the top down, if required, using Inclinalysis™ software. Incremental Displacement The Incremental Displacement is the difference in values of mean deviation between the base file (i.e., the first set of readings taken) and a selected file(s) (usually the latest set of readings) at each depth. This plot can be generated using Inclinalysis™ software. Cumulative Displacement The Cumulative Displacement value at a particular depth is the summation of incremental displacements starting from the bottom up to that particular depth. The profile represents the actual movement (or displacement) which has occurred at all depths between the times that the two sets of readings were obtained.

4.3.9 ADD READINGS The Digital Inclinometer app’s primary function is to take readings at the borehole. The “Take Reading” feature commences when the user selects the Add Reading function from the View Borehole Readings screen.

ICM0099A 23

MEMS Digital Inclinometer System with Android Instruction Manual

The Digital Inclinometer app first ensures the reel and probe are functional and communicating with the app via Bluetooth. The Digital Inclinometer app then performs integrity checks by verifying that the probe type is a vertical probe and the units in the probe match the borehole units configuration. The user is notified of incorrect configurations and prevented from taking readings. If the integrity checks are correct and the reel/probe are successfully connected through Bluetooth, the user may commence taking the displacement readings. The reading involves measuring the Axis A+ depths followed by reading measuring the Axis A- depth after the probe is rotated 180 degrees. Axis A+ Take Readings Process – First Pass The probe is first lowered to the lowest depth of the borehole. Once the probe is at the correct depth and remains stationary, the real-time reading stabilizes. The new readings screen shows the status of the probe readings refreshed approximately once every second. Figure 19 shows a sample Axis A+ reading at the bottom depth and the Axis A+ reading at the top depth.

Figure 19 – Axis A+ reading at bottom depth (10m) and top depth (0.5m) Axis A and Axis B shows the instantaneous lateral displacement in meters or feet. The Noise (uV) is the difference between the current reading and the previous reading measured in microVolts. A small difference or noise level indicates a stable and accurate reading. The noise level is color coded, where an optimal low noise level is displayed in green, a marginal noise level is displayed in orange, and a high noise level is displayed in red. The noise level varies based on each borehole location. In noisy environments (i.e., locations with in the vicinity), the acceptance criteria for a reading may be different based on environmental conditions. If the user deems the probe reading is acceptable, the user taps the ACCEPT button. The Digital Inclinometer app then repeats the process for the next depth. If the user deems any of the previously accepted readings on the Axis A+ is improperly taken, the user may request a re-take on any depth. The user lowers the probe to the re-take depth. On the Digital Inclinometer app, the user scrolls to the depth and taps the RETAKE

ICM0099A 24

MEMS Digital Inclinometer System with Android Instruction Manual

ALL or RETAKE SINGLE button for that reading. The two retake options are defined as follows: • RETAKE ALL requires that the user retake all readings from the retake depth to the top of the borehole. • RETAKE SINGLE requires that the user retakes just the reading of the selected depth and the app resumes from the current depth. The user is prompted to confirm the re-take reading request. Axis A- Take Readings Process – Second Pass The depth reading continues until the probe reading reaches to the top depth. Once the top of the hole has been reached, the Digital Inclinometer app prompts the user to turn the probe 180o and lower it back to the bottom of the hole. This is the Axis A- reading. The Digital Inclinometer app starts the Axis A- depth at the lowest borehole depth. The Axis A- depth reading is similar to the Axis A+ depth reading, but a new checksum data field is visible. The checksum data appears to the right most column preceded by a delta symbol. The real- time checksum value allows the user to monitor the second set of readings. If the checksum is large or inconsistent, either the probe has fouled or the probe is not at the correct measurement depth. Similar to the Axis A+ procedure, the user continues to take readings until the top of the borehole is reached. If the probe is accidentally raised above the measurement point, the probe should be lowered back down below the proper depth and then raised slowly to the correct depth. This ensures consistent and accurate readings. Figure 20 shows a sample Axis A- reading at the bottom depth and the Axis A- reading at the top depth.

Figure 20 – Axis A- reading bottom depth (10m) and top depth (0.5m) If the user deems any of the previously accepted readings on the Axis A- is improperly taken, the user may request a re-take on any depth. The user lowers the probe to the re-take depth. On the Digital Inclinometer app, the user scrolls to the depth and taps the RETAKE ALL or RETAKE SINGLE button for that reading. Once the top depth is reached on the second pass, the Digital Inclinometer app displays a prompt indicating the reading process is completed and the readings are automatically saved in the device’s memory.

ICM0099A 25

MEMS Digital Inclinometer System with Android Instruction Manual

4.3.10 ADD READINGS – DELETE AND CONFIGURE The user accepts the displacement reading as the probe ascends or descends to different depths. During this data collection process, the user may require changes to the data collection. The delete and configure icon, located at the top of the top status bar, permit additional functions that affect the take reading workflow. Delete Entire Reading The field personnel may wish to abandon a reading that was earlier started either intentionally or inadvertently. A confirmation prompt is displayed. Upon confirmation, the Digital Inclinometer app permanently removes the reading from readings list. A sample workflow of a delete readings process is shown in Figure 21.

Figure 21 – Delete reading

Modify Reading Options The user may modify the filter or the display of the reading by tapping on the configure icon located on the right corner of the top status bar. The Digital Inclinometer app displays the following reading options: • Decimal digits – the number of digits displayed. • Enable or disable audible notification – the audible notification is generated each time the reading is accepted. • Enable or disable averaging filter – the averaging filter averages the most recent readings to display a more stable reading. • Number of readings for averaging filter – tf the averaging filter is enabled, this parameter defines the number of recent readings to incorporate in the averaging filter. • Show or hide noise bar – This setting shows or hides the noise bar.

The changes to the reading options are only applied after tapping on the SAVE CHANGES button.

A sample workflow of a modify reading options is shown in Figure 22.

4.3.11 ADD READINGS - DATA AND GRAPH The Add Readings feature is equipped with data view and data graphing capabilities. These facilities are intended to allow the user to view the data during the collection of reading to assist with data validation. Data View Data View tabulates the recorded readings during the reading process. As readings are collected, new reading entries are added to the Axis A+/A- and Axis B+/B- table. The user has the options to view the data collected for Axis A or Axis B and display the data in Decimal or Scientific notation. Sample data visualization is shown in Figure 23.

Figure 23 – Sample Axis A+ and Axis A- reading Graph View The Readings Graph feature plots the accumulated data from either Axis A or Axis B. The three plotting options are: • Checksum • Mean Deviation

ICM0099A 27

MEMS Digital Inclinometer System with Android Instruction Manual

• Absolute Position The Digital Inclinometer app generates graphs based on the available data collected during the reading process. For borehole depths that have not yet collected readings, the lines are interpolated with dotted lines instead of solid lines. Figure 24 show sample graph types with data collected up to a depth of 6 meters.

Figure 24 – Sample Absolute, Mean Deviation and Checksum plots Checksum Checksum in A+/A- plane = A+ plus A- Checksum in B+/B- plane = B+ plus B- Checksum should be reasonably constant and of small magnitude, large and inconsistent Checksums may indicate that a problem exists. However, the consistency of checksums from survey to survey is more important than the actual value of the checksums. Checksum data should be monitored during the survey as a check on data integrity. Note that high checksums can be expected if a settlement coupling has been encountered, a checksum of the order of (+0.0045m and -0.0035m) or (+0.0147ft and –0.0114ft) would be reasonable at consecutive depths/couplings. Mean Deviation A+/A- mean deviation in the A+/A- plane = (A+ minus A-)/2 B+/B- mean deviation in the B+/B- plane = (B+ minus B-)/2 This represents the mean deviation at each depth. Absolute Position An Absolute Position value at a particular depth is the summation of mean deviations starting from the bottom up to that particular depth. Absolute position is the profile of the access tube with respect to the vertical axis in a given plane. Absolute position can also be calculated from the top down, if required, using Inclinalysis™ software.

4.3.12 EXPORT READING FILES OVERVIEW The Digital Inclinometer app supports features for measurement and data visualization at the borehole. Data readings may also be exported to remote facilities for offline analysis packages such as the RST Inclinalysis™ software.

ICM0099A 28

MEMS Digital Inclinometer System with Android Instruction Manual

The export feature is available by tapping the Measure icon at the bottom left corner of the bottom status bar followed by tapping the Import/Export selection. The export feature permits the user to select the desired site(s) and borehole(s) to export. Figure 25 shows a sample export screen.

Figure 25 – Export Screen The Digital Inclinometer app supports two mechanisms to export reading files: • Export Files to the Android Internal Storage, and • Export Files to Email Recipient(s).

4.3.13 EXPORT READING FILES TO ANDROID DEVICE (INTERNAL STORAGE) Exporting reading files to the Android device’s internal storage stores the selected site(s) and/or selected borehole(s) on the Android device. This folder can be accessed via PC by using a USB file transfer cable and selecting the Android System USB mode to be used for File Transfer. See Appendix B-3 for detailed instructions on setting the Android for file transfer to a PC. The exported reading files are always stored in the folder: Internal shared storage\Android\data\com.rstinstruments\files\export\DigitalInclinometer

The DigitalInclinometer folder contains subfolders for the exported site(s). From each exported site(s), the borehole reading files are available to be transferred from the Android device to a PC for analysis.

4.3.14 EXPORT READING FILES TO EMAIL RECIPIENTS The Digital Inclinometer app may export reading files to one or more email recipients. The Android device should be equipped with internet access either from a cellular data service or Wi-Fi. The Android device must be pre-configured with a valid Email account on the email app such as Google Gmail. If all services are available, the app compresses the selected site and borehole files into a zip package named DigitalInclinometer.zip. The Digital Inclinometer app automatically launches the built-in email service on the Android device. If more than one email service is available on the Android device, the user may choose the desired email service.

ICM0099A 29

MEMS Digital Inclinometer System with Android Instruction Manual

Enter the recipient(s) email address. The subject line and composition are optional fields. Upon completion of the email, tap the send icon to send the email. Figure 26 shows a sample of the email workflow.

Figure 26 – Export via email The DigitalInclinometer.zip file contains the folder DigitalInclinometer as the root folder. The DigitalInclinometer root folder contains subfolders for the exported site(s). From each exported site(s), the borehole reading files are available.

4.3.15 IMPORT READING FILES OVERVIEW The Import Reading Files is a feature that allows data collected from another device from the DigitalInclinometer app to be imported and added to the Android app. This feature allows borehole reading data to be shared amongst the different app platforms (Android, Field PC and Inclinalysis). The Digital Inclinometer app supports two mechanism to export reading files: • Import Files from Android Internal Storage • Import Zip file

4.3.16 IMPORT FILES FROM ANDROID INTERNAL STORAGE Importing reading files from Android storage retrieves the reading files from a specific folder in the Android device. This folder can be accessed via PC by using a USB file transfer cable and selecting the Android System USB mode to be used for File Transfer. See Appendix B-3 for detailed instructions on setting the Android for file transfer to a PC. The reading files for import are always stored in the folder: Internal shared storage\Android\data\com.rstinstruments\files\import\DigitalInclinometer

The DigitalInclinometer folder contains subfolders for the imported site(s). The data from the import folder are imported to the Digital Inclinometer app when the app is launched. The Digital Inclinometer app deletes content of the import folder after importing the content.

ICM0099A 30

MEMS Digital Inclinometer System with Android Instruction Manual

4.3.17 IMPORT ZIP FILE FROM STORAGE The import zip file allows the user to import a zip file that was exported or emailed by another Android device. The zip file is an archive that contains the DigitalInclinometer folder structure. The zip file may be stored on an external thumb drive or in the Android internal storage area. The Import Zip File opens up the Android file manager that allows the user to select the location of the zip file. The user selects the desired zip file to import into the Digital Inclinometer app.

4.3.18 REEL AND PROBE STATUS The Digital Inclinometer app utilizes reel, probe and battery status icons located at the bottom status bar. Status indicators may be expanded to view the communication mode between the app and the reel or probe. Figure 27 shows a sample communication status display.

Figure 27 – Communication status between the App and Reel/Probe/Battery

The communication status is designed to provide additional diagnostic information. The current list of diagnostic information is shown in Table 6. Table 6 Diagnostic information for the reel and probe Device Status Description Reel Disconnected App is searching for a Bluetooth connection to the reel Reel Connected App has established a Bluetooth connection to the reel Reel Updating reel battery state… App has received an update of the battery voltage indicating successful communication with the reel Reel Percentage Most recent battery level status Battery Probe Disconnected App is unable to communicate with the probe Probe Connected App has established a Bluetooth connection to the Reel

Probe Connecting to probe… App has received update of the probe status indicating successful communication with the probe.

4.3.19 DEVICES LIST The Digital Inclinometer app retrieves the reel and probe information during each connection. The RST support team may require information on the reel and/or probe information for diagnostic purposes. The reel and probe information are available by tapping the Measure icon at the bottom left corner of the bottom status bar followed by tapping the Devices selection. The Digital Inclinometer App displays a listing of available reels grouped into two categories: • MY DEVICES lists the reels that are within Bluetooth coverage of the app and that the app had connected in the past. The app attempts to automatically connect to one of the reels in the MY DEVICES list when the app is launched. De-activate the reels from the MY DEVICES list by tapping the FORGET label. Figure 28 shows a sample Devices list. • AVAILABLE DEVICES lists the reels that are within Bluetooth coverage of the app. The app does not automatically connect to these reels. Select any of the devices from this list to activate into the MY DEVICES list.

Figure 28 – Sample devices list

The Reel ID is typically displayed as DRxxxx where xxxx is the last 4 digits of the serial number. The user should always check the serial number of the reel with the connected serial number on the app. If the connected reel is not the desired reel, select the desired reel from the list. Select a different reel to connect or view the information on the current connected reel and probe.

4.3.20 REEL AND PROBE INFORMATION The Android app extracts information from the connected reel and probe. The user may view the information by tapping the information icon as shown in Figure 29. Reel Information • Status – current connection status to the reel

Figure 29 – Reel and probe information

5 PROBE TYPES VERTICAL PROBE Vertical probes collect data in the A and B axes. They are the most commonly used probes. Readings taken from an inclinometer probe are actually deviations from the vertical over the distance between the upper and lower wheels. When the probe is passed through the inclinometer casing, a reading is taken every 0.5m (or 2ft.). When the probe is at rest, the MEMS accelerometers sense the inclination of the access tube in two planes. This inclination is displayed in terms of angular deviation, which is recorded at that particular depth. HORIZONTAL PROBE The function of the MEMS Horizontal Inclinometer Probe is very similar to the standard biaxial (vertical) probe. Each individual survey requires the probe to be drawn or pulled through the casing, then reversed and passed through the casing again (probe is reversed end for end – not rotated axially 180° as in a vertical inclinometer survey). Measurements are collected at 0.5m intervals with the metric probe or 2 ft intervals with the imperial probe.

ICM0099A 33

MEMS Digital Inclinometer System with Android Instruction Manual

The readings taken represent the vertical displacement, defined by (½m)*(SIN (a)), where “a” is the angle between the horizon and the longitudinal axis of the probe. INCLINE PROBE The Incline probe measures inclination in a borehole at 35-degree tilt. Measurements are made in a single pass along the A axis. Since there is only one pass, A- is filled up with A+ readings of opposite sign. The A axis data represent displacements from 35-degree angle on the length of the probe. The B axis data is collected from another vertical sensor. Since that sensor is at an angle too big to read accurately, it is used here for a reference to show that the probe was inserted correctly. Data in B axis should be as close to zero as possible.

There is no need to edit data files to be able to display graphs in Inclinalysis. Inclinalysis can be easily switched to the graph of the A-axis to show the important graph only. COMPASS PROBE The Compass probe provides azimuth data for horizontal installations. The probe is passed through the inclinometer casing and compass sensors read azimuth at pre-set intervals. SPIRAL PROBE The RST Digital Spiral Probe is designed to complement the RST Digital Inclinometer System. In situations where excessive spiral is present in the inclinometer casing, it becomes important to correct for the spiral in order to have the correct magnitude of displacement in the A and B axes. The software displays the spiral readings directly in degrees. the spiral data is done in a similar manner as an inclinometer survey. To begin the survey, push Start button. The initial position is then measured. Accept button needs to be pressed when in manual mode. In Auto Accept mode, the probe will sense movements and the reading will be taken automatically without the need to press any buttons. The reading mode can be changed on Options screen. Refer to the RST Digital Inclinometer Spiral Sensor Manual (ICM0039) for further information. 6 WHAT DOES THE DATA MEAN? The system has been developed to accurately measure the lateral movement of earthworks and structures. The probe is passed through the inclinometer casing and takes a reading every 0.5m (or 2ft). When the probe is at rest, MEMS accelerometers sense the inclination of the access tube in two planes. This inclination is displayed in terms of angular DEVIATION, which is recorded at that particular depth.

A+ = Face A+ deviation A- = Face A- deviation B+ = Face B+ deviation B- = Face B- deviation

CHECKSUMS

Checksums serve two purposes. The first is to allow the user to visualize the magnitude of the systematic bias that may exist in the probe, just in an informative way, as the checksums are not used in any further calculation. That systematic bias is then cancelled by using the Mean deviation defined below in further calculations such as the Cumulative displacement, the Incremental displacement and the Absolute profile. The other purpose of the checksums is to act as a diagnosis of the quality of a given survey in the sense that if an individual reading shows a high checksum that was not present at the

ICM0099A 34

MEMS Digital Inclinometer System with Android Instruction Manual

same elevation in an earlier survey conducted at a previous date, it may mean that one of the two readings in the + or - direction was not done properly, and the user will then be able to repeat that same reading in order to restore the checksum to a similar lower value as in previous surveys. Checksum in A+/A- plane = A+ plus A- Checksum in B+/B- plane = B+ plus B- The checksum should be reasonably constant and of small magnitude, typically less than +/- 2 mm (0.08 in) and preferably less than +/- 1 mm (0.04 in). Large and inconsistent checksums may indicate that a problem exists. However, the consistency of checksums from survey to survey is more important than the actual value of the checksums. Checksum data should be monitored during the survey as a check on data integrity. Note that high checksums can be expected if a settlement coupling has been encountered, a checksum of the order of +/- 4 mm or (+/- 0.16 in) would be reasonable at consecutive depths/couplings.

MEAN DEVIATION A+/A- mean deviation in the A+/A- plane = (A+ minus A-)/2. B+/B- mean deviation in the B+/B- plane = (B+ minus B-)/2. This represents the mean deviation at each depth, corrected for any systematic bias that can be present in the inclinometer probe as the average of the two measurements opposed at 180 degrees cancel that bias. ABSOLUTE POSITION An absolute position value at a particular depth is the summation of mean deviations starting from the bottom up to that particular depth. Absolute position is the profile of the access tube with respect to the vertical axis in a given plane. Absolute position can also be calculated from the top down if required using Inclinalysis™ software. INCREMENTAL DISPLACEMENT The incremental displacement is the difference in values of mean deviation between the base file (first set of readings taken) and a compatible file (usually the latest set of readings) at each depth. This plot can be generated using Inclinalysis™ software. CUMULATIVE DISPLACEMENT The cumulative displacement is the result of comparing two sets of mean deviations, usually the base file and the latest or comparison file. The profile represents the actual movement (or displacement) which has occurred at all depths between the times that the two sets of readings were obtained. 7 SYSTEM COMPATIBILITY Regardless of the inclinometer system being used, it is imperative that the probe wheels be placed at the same locations during each profiling of the borehole (this is not necessarily the same depth marked on the inclinometer cable). Always use a consistent top reference, such as the aluminum cable grip which is provided with all RST Inclinometer systems. The zero-depth reference on the new RST Digital Inclinometer System refers to the midpoint of the probe (between the wheel assemblies). This is the industry standard. The old RST analog system is referenced to the uppermost set of wheels. Therefore, this must be taken into account if the customer wishes to directly compare the two sets of readings. It is very important that the data be within 4mm (0.25”). Otherwise, the data will not match, and the comparison will not be valid.

ICM0099A 35

MEMS Digital Inclinometer System with Android Instruction Manual

Note Customers wishing to compare surveys between RST’s old analog system and the new digital system must ensure that the readings of both systems are taken at the same depths (with the proper depth reference). If you are changing over to the new Digital Inclinometer System, as with any new system, it is good practice to survey the borehole with both systems. When it is determined that the data from the new Digital System is satisfactory, the user can stop using the older system and continue from that point forward.

Note Some competitor’s have different cable gripping/locating systems resulting in different depth locations. You must be aware of these differences when trying to directly compare data between the two different systems.

8 CARE AND MAINTENANCE PROBE & REEL CONNECTORS Proper care and maintenance of the digital probe and reel connectors will ensure trouble- free operation of the Digital Inclinometer System. Failure to adhere to the following guidelines can result in premature connector wear, and ultimately connector failure: • Ensure the keyway is aligned before threading the connector together. • Never over-tighten the bulkhead connectors when mounting. Snug (hand-tight) is more than sufficient. • Only twist the brass coupling on the connector, do not twist the signal cable itself. • Avoid sharp bends at the cable entry to the connector. Failure to do so may result in irreparable damage to the internal cable wires. • Clean the plugs and receptacles with a mild soap and fresh water on a regular basis. Do not allow the connectors to become excessively dirty. Never thread the connector when there is debris inside. • Rinse out the connector with alcohol, allowing it to air dry. Replace the dust caps once the connector is dry. • Lubricate the mating surfaces with the supplied silicone spray on a regular basis. DO NOT GREASE and avoid the use of any solvent based (such as WD-40). • The amount of silicone spray used should be based on the frequency of use of the probe. One light spray to cover all contacts is enough after cleaning the connector. Ensure the connector is clean and dry before applying the silicone spray. o Contact RST Instruments to purchase a replacement bottle of silicone spray. o The RST recommends 3M Silicone Lubricant (Part # 62467849303), or Haynes Silicone Oil. • Elastomers contained in the connector can be seriously degraded if exposed to solvents, direct sunlight, or high ozone levels for extended periods of time. Always replace the dust caps once the connector is clean and dry. • Always keep the dust caps clean and free of any foreign materials. Do not place the dust caps where they may become contaminated.

ICM0099A 36

MEMS Digital Inclinometer System with Android Instruction Manual

• Always use the dust caps and keep the connectors clean to prevent damage in storage and when in use. Warning Solvent-based lubricants (such as WD-40) should NEVER be used as a lubricant on the connectors. These products will damage the elastomers in the connectors resulting in loss of communication with the digital probe. ONLY use the supplied silicon lubricant or an RST-approved equivalent. If ever in doubt or any questions arise, do not hesitate to contact RST Instruments for further information.

INCLINOMETER PROBE The digital inclinometer probe consists of high-grade stainless-steel components and is completely sealed; minimal maintenance is required. • After the borehole survey is complete, wipe all moisture off the probe and replace the protective caps over the connectors. If required, rinse the probe in clean water and dry. If the probe is exceptionally dirty, use a mild soap and fresh water to clean. • Never use solvents to clean the probe, wheels, or connectors. • Always store the probe in its original case whenever it is not in use. The high precision accelerometers in the probe can be damaged if the probe is subjected to excessive shock or vibration. • Keep both the probe and its case clean and dry. If the probe is not cleaned and dried in the field, be sure to clean and dry it (including the case) upon return to the office. Do not leave corrosive solutions (i.e. saltwater) on the probe, connectors, and cable; be sure to clean the parts if these conditions exist. The probe wheels are made with high-grade hardened and heat-treated stainless steel. These are the most robust on the market and are extremely durable. The wheels contain sealed bearings which require no maintenance, except keeping them clean and dry. Exposing the bearings to any particulates should be avoided to avoid contamination. • The bearings do not require lubrication; never use a solvent-based lubricant (such as WD-40) on the wheel bearings as this may accelerate bearing degradation. • DO NOT replace a damaged shear pin in the wheel assembly without consulting RST. Failure to do so may irreparably damage the probe and/or wheel assembly. REEL AND CABLE If required, wipe the cable with a clean rag to dry it off after use. The cable has a durable polyethylene jacket; simply use water and a mild soap to clean it off if necessary. The spacing between the aluminum cable crimps and the total length of the cable should periodically be measured. This will verify the accuracy of downhole depth measurements and the ensure maximum repeatability of the inclinometer system readings. Ferrule spacings should be measured between the downhole edge of each ferrule (i.e. ferrule edges closest to the cable connector) and should be 0.5m for Metric cables and 2ft for imperial cables. Ensure to tension the cable to remove any slack while making these measurements.

Warning If the surveyed borehole has alkaline groundwater conditions, flush the borehole with fresh water prior to taking readings, and thoroughly rinse the cable with fresh water after the survey is complete. This will help to minimize potential corrosion of the aluminum cable crimps.

ANDROID DEVICE To keep the Android device in good condition and working properly, please adhere to the following guidelines: • Keep the Android device away from excessive moisture and extreme temperatures. Do not expose it to or precipitation. • Do not place anything on top of the device to prevent damage to the screen. • Clean the unit by wiping the screen and the exterior with a soft, damp cloth moistened only with water. • Avoid exposing the Android device to direct sunlight or strong ultraviolet light for extended periods of time. Also avoid scratching the surface of the screen and banging it against hard objects. For further reference please see the supplied manufacturer’s manuals for the selected Android device. CALIBRATION RST strongly recommends that the probe be sent in for calibration annually. Due to the high precision nature of the sensors and the sensitivity of the probe, calibration must be done to ensure quality results and continued performance of the probe. Heavy use in adverse conditions may require calibrations to be done more often. Calibration should also be performed if the probe has been dropped or become damaged in any way. If checksums become significant and they are not due to errors in probe positioning or noise, the probe likely needs to be re-calibrated. Calibration should also be performed after any wheel assembly replacement. 9 IMPORTING AND EXPORTING FILES SAVING AND IMPORTING INCLINOMETER DATA INTO DIGIPRO SOFTWARE The RST Digital Inclinometer *.csv data files can be imported directly into DigiPro software.

Appendix A CHANGING THE BATTERY (FOR REELS WITH SERIAL NUMBERS UNDER 2500) Batteries inside reels with serial numbers under 2500 may be removed for recharging. The reel uses a 7.4V lithium-ion camcorder battery. The system comes with a battery housed inside the reel and a charger. Adapters are supplied to allow the charger to function in a

(12V DC), or 110-240V AC power (see XFigure 1X). Reel batteries should be kept at a state of full charge whenever the probe is not in use. To remove the battery, simply unscrew the cap off the reel hub by turning it counter-

clockwise (Figure 30X).

Figure 30 – Battery Removal / Installation

Remove the battery and place on the Mach 1™ Speed Charger. Mach 1 Speed Charger Operating Instructions Status LED’s Together, the three LED’s on the front of the Mach 1 charger will indicate the status of the battery and the charger. The descriptions and diagrams included in the following sections describe the various indicators and their meaning. Standby Mode Without any battery installed, the charger will flash the LED on the left, marked MED, indicating that the charger is standing by and waiting for a battery to be connected.

STANDBY FLASHING OFF OFF MED HI MAX Figure 31 – Standby Mode Once a battery has been properly connected to the charger, it will determine the status of the battery and begin the proper phase of the charging cycle. There are 3 phases to the charge cycle. The battery may be removed during any of the charging phases without harm to the battery or charger unit.

Phase I – Initial Charge All 3 LED’s flashing in sequence from MED (left) to MAX (right). If the battery is low, this will be the first charge phase. With high capacity batteries, this phase can sometimes be the longest of the 3 phases. Similarly, with some low capacity batteries and batteries reaching the end of their life, this phase can be very short.

UNote:U When the battery is first connected, the LED’s may instantly indicate MED, HI or MAX charge depending on the charge status of the battery. The process will continue normally from that point forward.

UNote:U It is normal for the charger, AC adapter, or the battery to become warm during charging. Phase II – MED Charge The MED LED is on continuously and the other LED’s are flashing in sequence. At this point the battery is typically about 50% charged. Some very small capacity batteries (650mAh) and worn out batteries can be as low as 10% charged.

Charge Complete ON ON ON MED HI MAX Figure 35 – MAX Charge Error Condition – Charge Terminated If the battery is removed before a complete charge has been reached, the charger will continue indicating the last complete charging phase for up to 1 minute. After that time, an “Error” indication will appear on the LED’s, shown by the MED and MAX LED’s coming on together while the HI LED is off.

ICM0099A 44

MEMS Digital Inclinometer System with Android Instruction Manual

Error Condition ON OFF ON MED HI MAX Figure 36 – Error in Charging The Error Condition will also be indicated if the charger senses and problem with the battery being charged. To reset the error condition, unplug the charger from the power adapter for a few seconds, and then reconnect it. If the Error occurs again, there may be a defect in the battery that will prevent safely charging. Charging Time The 7.4V 2200mAh Lithium-Ion batteries supplied with the inclinometer system will take approximately 80 minutes to fully charge if they are depleted. Note RST strongly recommends that all batteries should be taken out into the field fully charged at the beginning of each day.

Be aware that cold temperatures can also have an effect on the performance of the batteries. Expect a somewhat shorter operation in extremely cold temperatures. Under adverse conditions, it is recommended that extra batteries be taken to the field, where one can be charging in between readings of several boreholes. The reel batteries are a standard camcorder battery and are readily available. Note The batteries will self discharge when not in use whether they are installed in the inclinometer reel or not. Batteries can be kept fresh if recharged on a regular basis.

Upon replacement of the battery, ensure to align the battery contacts with the contacts in the Reel hub to allow proper operation. Installation is the exact opposite of removal. Please ensure that the battery contacts line up with the contacts contained within the hub for correct operation. Battery Life A single Reel battery has the ability to last for up to 1 week on standby mode (i.e. no connection to the Ultra-Rugged Field PC). However, it is a good practice to turn off the Reel power whenever the survey is complete, as leaving the power on will eventually drain the battery. At room temperature, while taking readings, battery life is approximately 30 hours. In extreme environmental conditions (extreme cold or hot temperatures) fully expect useable battery life to decrease. It is always a good practice to take 2 or more fully charged batteries out in the field before performing inclinometer survey work.
