Thermocouple Commands

[SENSe:]TEMPerature:TRANsducer :TCouple:TYPE {BEJKNRST}[,(@<ch_list>)] :TCouple:TYPE? [(@<ch_list>)]

Select the thermocouple type to use on the specified channels.

The default is a J-Type thermocouple. The :TYPE? query returns the thermocouple type currently in use. Returns “B”, “E”, “J”, “K”, “N”, “R”, “S”, or “T”.

[SENSe:]TEMPerature:TRANsducer:TCouple :RJUNction:TYPE {INTernalEXTernalFIXed}[,(@<ch_list>)] :RJUNction:TYPE? [(@<ch_list>)]

Thermocouple measurements require a reference junction temperature. For the reference junction temperature, you can use an internal measurement on the module, an external thermistor or RTD measurement, or a known fixed junction temperature. The default is “INTernal”.

The :TYPE? query returns the source currently selected. Returns “INT”, “EXT”, or “FIX”.

∙If you select an external reference, the instrument automatically reserves channel 01 on the multiplexer in the lowest slot as the reference channel (thermistor or RTD measurement). If you have more than one multiplexer installed, channel 01 on the module in the lowest slot is used as the reference for the entire instrument.

∙Before configuring a thermocouple channel with an external reference, you must configure the reference channel (channel 01) for a thermistor or RTD measurement. An error is generated if you attempt to select the external reference source before configuring the reference channel. An error is also generated if you change the function on the reference channel after selecting the external reference for a thermocouple channel.
