[SENSe]
Parameters
Comments •
Use SENS:FUNC:TEMP:POST to configure channels to measure thermocouples.
Then use SENS:REF:POST to configure one or more channels to measure an
isothermal reference temperature. Finally, use SENS:REF:CHAN:POST to
group the reference channel with its thermocouple measurement channels.
•
If thermocouple measurements are made through more than one isothermal
reference panel, set up a reference channel for each. Execute the
SENS:REF:CHAN:POST command for each reference/measurement channel
group.

[SENSe:]REFerence:TEMPerature
[SENSe:]REFerence:TEMPerature <degrees_c> stores a fixed reference junction
temperature in the Reference Temperature Register. Use when the thermocouple
reference junction is kept at a controlled temperature.
Note
This reference temperature is used to compensate all subsequent thermocouple
measurements until the register is overwritten by another SENSE:REF:TEMP value
or by scanning a channel linked with the SENSE:REFERENCE command. If used,
SENS:REF:TEMP must be executed before scanning any thermocouple channels.
