I have a question:
Using an Agilent Datalogger, with approximately 40 thermcouples placed directly onto the units we are testing in a thermal chamber from -40C to +70 C . We also have thermocouples plcaed in free air positions ( low, middle, top) of the racks holding the test units, and also at the air intake and air exhaust of the chamber.
The question I have is :
What is a quick method to check that all the thermocouples are reading the same temperature ? My reason for asking is that on the last test run, a couple of the channels apeared to have temperture reading results that were significantly different from the other sensors.
Would it make sense to place all the sensors close together on a metal plate, inside the chamber, and get readings at cold, ambient, and high temperatures ?
Thanks for any suggestions and advice !
