Default ? Meter to test thermoelectric potential of unknown metal

I would also assume it measures thermoelectric voltage. I have a meter
at work that connects directly to a T type thermocouple. If it has the
meter movement sensitivity printed anywhere I'll let you know. Your
meter face may also have it but sometimes you can't see it unless you
look pretty hard...


If it's a straight connection to the movement, it may show both a
current and the internal resistance (eg. 50uA/500 ohms), and in the
case of a thermocouple meter like yours, it may have a presumed
resistance value for the total thermocouple circuit (eg. 10 ohms).
