causes channel
specified by <ref_channel> to appear in the scan list just before the channel(s)
specified by <ch_list>. This command is used to include the thermocouple reference
temperature channel in the scan list before other thermocouple channels are measured.

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