Remote Interface Operation:
You can use the
CONFigure
or
MEASure?
command to select the probe type and thermocouple type. For example,
the following command configures channel 3001 for a J- type thermocouple
measurement.

You can also use the
SENSe
command to select the probe type and
thermocouple type. For example, the following command configures
channel 2003 for a J- type thermocouple measurement.
SENS:TEMP:TRAN:TC:TYPE J,(@2003)
The following commands use the
SENSe
command to set a fixed reference
junction temperature of 40 degrees (always in °C) on channel 2003.
SENS:TEMP:TRAN:TC:RJUN:TYPE,(@2003)
SENS:TEMP:TRAN:TC:RJUN 40,(@2003)
The following command enables the thermocouple check feature on the
specified channel (opens are reported as “+9.9037”).
