-wire Resistance S2
Sensor line resistance relevant for all Pt, Ni, Cu resistance thermometers with a two
-wire circuit
Value range:0 to 100 Ω
Thermocouple CJC 2
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 reference junction compensation (CJC)
• Sensor 1 Temperature: Use of Sensor 1 as reference junction temperature for Sensor 2
Ext. CJC Temperature 2
Relevant for external reference junction compensation, specification of constant external reference junction temperature.
Value range:
-50 to 100 °C
