Question

What happens if the thermocouple lead wires or compensating lead wires are too long?

Answer

The lead wire resistance increases and the temperature displayed will be higher than the actual temperature. Make sure that the thermocouple lead wires or compensating lead wires are not affected by lead wire resistance.

Use thick wires as compensating lead wires.

Change the wiring location to shorten the lead wires.
