VT1422A Command Reference 359Chapter 7
[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.
•Related commands: SENS:FUNC:TEMP:POST, SENS:REF:POST
•*RST Condition: No channels are linked to references.
•Send with VXIplug&play Function: hpe1422_cmd(...)
Usage SENS:FUNC:TEMP:POST TC,J,.0625,(@10008:10015)
J type TCs on channels 8 through 15
SENS:REF:POST THER,5000,4,(@10000),(@10001) sense the reference temperature on
ch 10001; excitation on ch 10000;
measure on 4V range
SENS:REF:CHAN (@10001),(@10008:10015) link TC channels to thermistor
ROUT:SEQ:DEF (@10008:10015,10001,10000) set up scan list

[SENSe:]REFerence:TEMPerature

[SENSe:]REFerence:TEMPerature <deg rees_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.
