So I have a project with a couple of thermocouple cards on an Allen Bradley L33ER rack. The instruments aren't due in for a little while, and I want to test out the signal high/low. I have an analog signal generator for mA and 0-10, but thermocouples send in a mV signal, correct?
Any good way to bench test these inputs? Is it as simple as making a voltage divider with a potentiometer reducing the voltage to the mV range?
