<p>NSSPCM Test Documents</p><p>Test #8: Accurate Temperature Sensing </p><p>Purpose:</p><p>The objective of this test is to validate Engineering Specification 10. The test verifies that the NSSPCM firmware is sensing and reporting the correct temperature values. </p><p>Equipment Needed:</p><p> NSSPCM</p><p> Computer running Microsoft Windows, Eclipse and the Java Runtime Environment (1.6 32-bit) with javax.comm library installed.</p><p> USB A to Mini B Cable</p><p> TI MSP430 Launchpad</p><p> MAX3483 8PDIP</p><p> Breadboard and wire</p><p> NSSPCM Diagnostic Utility</p><p> Multimeter</p><p> Temperature Probe</p><p>Procedure: </p><p>1) Connect the A and B wires of the communication cable from the NSSPCM to the A and B connections of the MAX3483 chip on the breadboard.</p><p>2) Connect 3.3 V and GND to the MAX3483 chip.</p><p>1 NSSPCM Test Documents</p><p>3) Connect the RO pin of the MAX3483 chip to the TX pin of the MSP430 Launchpad. </p><p>4) Connect the DI pin of the MAX3483 chip to P1.4 on the MSP430 Launchpad.</p><p>5) Connect the RE and DE pins of the MAX3483 chip to P1.6 on the MSP430 Launchpad.</p><p>6) Connect the USB cable from the MSP430 Launchpad to the computer.</p><p>7) Start Eclipse and open the NSSPCM GUI Project.</p><p>8) Run the NSSPCM GUI Project and select the desired COM port. </p><p>9) Press the Ping button.</p><p>10) Press the Update Status button.</p><p>11) Place the temperature probe near the external temperature sensor.</p><p>12) Wait 5 minutes for the temperature to be accurately sensed.</p><p>13) Press the Update Ext Temp button.</p><p>14) Record the reported and measured temperature values</p><p>15) Place the temperature probe near the internal temperature sensor.</p><p>16) Press the Update Int Temp button.</p><p>17) Record the reported and measured temperature values.</p><p>18) Repeat steps 11 through 17 three times to ensure accuracy.</p><p>Acceptance Criteria:</p><p>2 NSSPCM Test Documents</p><p>To pass the test, the value reported by the NSSPCM GUI Monitor must be within ± 5 degrees Celsius of the actual value measured from the temperature probe. The test will fail if the difference between the reported value and the measured value is greater than 5 degrees Celsius.</p><p>Test Results:</p><p>Unit of Marginal Ideal Software Source Specification Measure Value Value Reported Value Measured Value ES10 Internal Temperature °C ± 5.0 ± 3.0</p><p>ES10 External Temperature °C ± 5.0 ± 3.0</p><p>Tester Name______Date (yyyy-mm-dd)______Pass/Fail______</p><p>Reviewed By______Date(yyyy-mm-dd)______Pass/Fail______</p><p>3</p>
