3. Check that you have the thermocouple's polarity correct by warming its tip. You will see
the Realtime temperature increase if the wires are connected correctly. If the
temperature decreases, reverse the connections.
NOTE: The inputs are not isolated from each other (they use the same common
"-" terminal internally). This means that the thermocouple tips cannot be touching
each other. If they are touching or are fastened to a conducting surface like a
metal frame, some looping can occur and the readings may fluctuate. They must
be insulated or prevented from making contact with each other electrically. Do
not use grounded thermocouples.
