to 100 Ω
Thermocouple CJC
Cold junction compensation for thermocouples:
•
Internal:Use of internal reference junction temperature of the transmitter when using thermal compensating cable.
•
External - fixed:Use of external fixed reference junction temperature of the transmitter when constant thermostat
temperature is used (can be set with external reference junction temperature 2).
•
None: no thermocouple cold junction compensation (CJC)
• Temperature sensor 1: Use of Sensor 1 as reference junction temperature for Sensor 2
Ext. CJC Temperature
Relevant for external cold junction
compensation , specification of constant external cold junction temperature
Value range:
-50 to 100 °C
