•
If using amplifier SCPs or RSCs, set them first and keep their settings in mind
when specifying a range setting. For instance, if the expected signal voltage is
to be approximately 0.1 V dc and the amplifier SCP for that channel has a gain
of 8, <range> must be set no lower than 1 V dc or an input out-of-range condition
will exist.

•
The *CAL? command calibrates channels based on Sense Amplifier SCP setup
at the time of execution. If SCP settings are changed, those channels are no
longer calibrated. *CAL? must be executed again.

links channel
in <ch_list> to the reference junction temperature EU conversion based on <type>
and <sub_type>. When scanned, the resultant value is stored in the Reference
Temperature Register and by default the FIFO and CVT. This is a resistance
temperature measurement and uses the on-board 122 µA current source.

temperature measurement and uses the on-board 122 µA current source.
Note
The reference junction temperature value generated by scanning the reference
channel is stored in the Reference Temperature Register. This reference temperature
is used to compensate all subsequent thermocouple measurements until the register
is overwritten by another reference measurement or by specifying a constant
reference temperature with the SENSE:REF:TEMP command. If used, the reference
junction channel must be scanned before any thermocouple channels. Use the
SENSE:REF:CHANNELS command to place the reference measuring channel into
the scan list ahead of the thermocouple measuring channels.
