[SENSe:]REFerence:CHANnels:POST

358 VT1422A Command Reference
[SENSe:]REFerence:CHANnels (@<ref_channel>),(@<ch_list>)
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.
Parameter Parameter
Name Type
ref_channel channel list (string)
ch_list channel list (string)
•
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.
•
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.

[SENSe:]REFerence:CHANnels:POST (@<ref_channel>),(@<ch_list>)
the thermocouple channel(s) specified by <ch_list> to the temperature reference
(thermistor) channel specified by <ref_channel>. The reference channel must be on
the same VT1529B as the thermocouple channels.
The ROUT:SEQ:DEF command must be used to include the thermocouple channels
in the scan list.
This command is valid only on the VT1529B and is available with VXIplug&play
driver revision A.01.09 or later (revision A.01.06 or later of hpe1422_32.dll).
