Channel (Configure) > TEMPERATURE > PROBE TYPE > RTD > . . . USE AS EXT REF?

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.

CONF:TEMP TC,J,(@3001)

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 “+9.90000000E+37”).

SENS:TEMP:TRAN:TC:CHECK ON,(@2003)

The following commands select the fixed reference junction source and set the junction temperature to 20 °C on the specified channel.
