HEALTH & SAFETY INFORMATION 5.1 GENERAL SAFETY INSTRUCTIONS For your own safety and the safety of others, and to prevent damage to the equipment and vehicles, read this manual thoroughly before operating your scanner. The safety messages presented below and throughout this user’s manual are reminders to the operator to exercise extreme care when using this device. Always refer to and follow safety messages and test procedures provided by vehicle or equipment manufacturer. Read, understand and follow all safety messages and instructions in this manual. Safety Message Conventions Used We provide safety messages to help prevent personal injury and equipment damage. Below are signal words we used to indicate the hazard level in a condition. ! DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury to the operator or to bystanders. ! WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to the operator or to bystanders. ! CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in moderate or minor injury to the operator or to bystanders. 5.2 SPECIFIC SAFETY INSTRUCTIONS Always use your oscilloscope as described in the user’s manual, and follow all safety messages. ! WARNING Do not route the test cables in a manner that would interfere with driving controls. Do not exceed voltage limits between inputs specified in this user’s manual. Always wear approved goggles to protect your eyes from propelled objects as well as hot or caustic liquids. Fuel, oil vapours, hot steam, hot toxic exhaust gases, acid, refrigerant and other debris produced by a malfunctioning engine can cause serious injury or death. Do not use the scanner in areas where explosive vapour may collect, such as in below-ground pits, confined areas, or areas that are less than 18 inches (45 cm) above the floor. Do not smoke, strike a match, or cause a spark near the vehicle while testing and keep all sparks, heated items and open flames away from the battery and fuel / fuel vapours as they are highly flammable. Keep a dry chemical fire extinguisher suitable for gasoline, chemical and electrical

  • Digital Power Analyzer Model 4301
    Model 4301 Modular Power Analyzer An All-Purpose Digital Measurement Instrument for Power Conversion Device Testing Model 4301 Modular Power Analyzer 0.1% reading and 0.1% range accuracy Up to 16 Power Analyzer modules in a single chassis 25 standard AC and DC, static and dynamic measurements Dual DSPs with 1MHz sampling rate 6 voltage and current ranges plus auto-ranging for increased accuracy Peak-Peak noise measurements, 10Hz - 20MHz Two Digital Logic Inputs per module Chassis communications through a PC/LAN with LabVIEW and IVI- compliant drivers Applications The Model 4301 Power Analyzer is primarily designed for use in automated test environments configured for simultaneous testing of multiple power conversion UUTs. The Analyzer’s advantage in this application are speed, size and measurement performance. Speed is achieved through having Model 4301 a single instrument capable of making a wide range of measurements dedicated to each test channel. Test system size is minimized through the modular single-card design, 16 of which can be fitted into a multi-instrument chassis. Measurement performance is achieved by deriving an extensive number of high accuracy measurements from a digitized waveform. This last capability is particularly useful where input as well as output measurements are necessary to precisely calculate UUT efficiency. 3 Instruments in 1 Through Waveform Digitization The 4301 Analyzer can be thought of as functionality equivalent to three instruments: a power meter, a multimeter and an oscilloscope. This capability is achieved through the Analyzer’s state-of-the-art, dual A/D converters with a 1MHz sampling rate that provides the data to make practically any power- conversion-related static or dynamic measurement provided by the three types of instruments above.

  • Lab 1 – Measurements of Frequency
    Physics of Music PHY103 Lab Manual Lab 1 – Measurements of Frequency EQUIPMENT and PREPARATION Part A: • Oscilloscopes (get 5 from teaching lab) • BK Precision function generators (get 5 from Thang or teaching lab) • Counter/timers (PASCO, 4 + 1 other) • Connectors and cables (BNC to BNC’s, banana plug pairs) connecting function/signal generators to oscilloscopes and speaker. • BNC to 2 leads • Adaptors: mike to BNC so that output of preamps can be looked at on oscilloscope. • BNC to banana adapters • BNC T- adapters • Oscilloscope probes • Pasco open speakers • Microphones, preamps, mic stands • Strobes (3) optional Warning: do not place speakers near oscilloscope screens as they can damage the CRT (cathode ray tube) screens. Note: The professor will attempt to have the equipment out and available for the labs. However the TAs/TIs should check that the equipment is ready to use, that every lab setup has all the necessary equipment. The TA/TIs should also be familiar with the lab and know how to troubleshoot the equipment. INTRODUCTION In this lab, we will be measuring the frequency of a signal using three different methods. The first method involves the use of the function generator. A function generator is an instrument that can produce sine, square, and triangular waves at a given frequency. The second method makes use of the oscilloscope. An oscilloscope is an instrument principally used to display signals as a function of time. The final method for measuring the frequency uses the counter/timer. A counter/timer is an instrument that can give a very accurate measurement of the frequency of a signal by counting each time a voltage crosses a particular value.
