I am trying to fix my soldering station. the actual iron part connects with a 5-pin connector... 2 pins for the heating element, 2 for the sensor, and 1 for an earth ground for the tip. The sensor measures almost zero ohms, so I am assuming it is a thermocouple and not a thermistor.
I don't have any real experience with thermocouples so could anyone give me some info on how i might test this thermocouple to see if it is working? The soldering station isn't working so obviously i can't just turn the thing on and let it heat up and see if i get any voltage out of it.
Would dunking it alternately between boiling water and ice water, while watching the output on an oscilloscope work?
please note that i'm only asking about testing the thermocouple in this post. I just want to verify that it is working, separately of the rest of the circuit. Advice for testing other parts of the circuit can be reserved for a different thread, which i'll probably post up once i finish reverse-engineering the whole schematic.
thanks in advance for your advice.
