2Features and Functions

Front Panel Operation: To select the thermocouple function on the active

channel, choose the following items.

DMM or Channel (Configure) > TEMPERATURE > PROBE TYPE > THERMOCOUPLE

Then, use the knob to select the thermocouple type from the list.

THERMOCOUPLE TYPE > BEJKNRST

If desired, you can enable the thermocouple check feature on the active channel (opens are reported as “OPEN T/C”).

T/C CHECK > OFFON

To select the reference junction source for the active channel, choose one of the following items.

REFERENCE > FIXEDEXTINT

For an external reference, configure an RTD or thermistor as the external reference channel.

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.

TEMP:TRAN:TC:RJUN:TYPE FIX, (@2003)

TEMP:TRAN:TC:RJUN 20, (@2003)
