If you are encountering large errors in the temperature of the Temperature Controller, you can check for the following five issues to help determine the cause.
1. Check that the correct input type is being used for the Temperature Sensor.

2. The lead wires and the power line for the Temperature Sensor may be routed through the same conduit. In this case, the lead wires are being affected by noise from the power line. (This is often the cause when the display value is changing erratically.)

3. Check that the Temperature Controller and Thermocouple are not connected with copper wire.
