A thermocouple uses two dissimilar metals that when heated will generate a small voltage. This is sent to the controller board which is what controlls the gas valve. If you need a very sensitive volt meter to read the millivolt (.001 volt) change when it is heated to see if it is functioning. The 30 millivolts in the above post is .030 volts when heated and functioning.
