8.5 Troubleshooting by Symptom
This section describes troubleshooting using the wiring resistance values of thermocouples.
8.5.1 When the temperature process value (PV) is abnormal
Check Item Action
Is the thermocouple wiring resistance value too high?
• Check the thermocouple wiring resistance value and check whether a
difference in the temperatures was caused by the wiring resistance.
( Page 40, Section 3.1.1)
• Use the sensor correction function to correct the difference in the
temperatures caused by the wiring resistance. ( Page 209, Section
4.14)
