Challenge:
The customer needed to test a thermistor in their in-flight entertainment system. Since the resistance value of the thermistor changes as the room temperature fluctuates, the customer wanted to avoid resetting the nominal resistance level in the test program every time the room temperature changed.
Solution:
Using a Touch1 custom component script, the user measures a reference thermistor to obtain the relative room temperature. The test is performed by comparing the resistance value of the reference thermistor to the resistance value of the thermistor in the device being tested. The user can specify how much difference can be tolerated. The device is tested before and after the molding process to ensure the part continues to function properly even after heat and pressure have been applied.
Results:
Using the Touch1 and custom component scripting, the customer received a simple and inexpensive way to compensate for room temperature changes while testing thermisters.
