Determining Temperature Controller Errors or Sensor Errors

Using a Thermocouple

If the controller displays a temperature that is close to room temperature (70ºF/21ºC) when you short- circuit controller input terminals, the controller is normal and the sensor is probably broken, short- circuited, or incorrectly wired.

Using a Platinum Resistance Thermometer

If the controller displays a temperature of about 0.0°C (32ºF) when you insert a 100-ohm resistor between terminals A and –Bof the controller, and you short-circuit controller terminals +B and

–B, the controller is normal and the sensor is probably broken, short-circuited, or incorrectly wired.
