[SENSe:]TEMPerature:TRANsducer:TCouple:TYPE
Syntax
[SENSe:]TEMPerature:TRANsducer:TCouple:TYPE <type> [, (@<ch_list>)]
[SENSe:]TEMPerature:TRANsducer:TCouple:TYPE? [(@<ch_list>)]
Description
This command selects the thermocouple type to use for measurements on the specified channels.
Used With:
34921A Armature Multiplexer (with optional 34921T Terminal Block)
34922A Armature Multiplexer
34923A Reed Multiplexer (differential mode only)
34924A Reed Multiplexer

{B|E|J|K|N|R|S|T}* |
J Type |
|
<ch_list> |
Numeric |
One or more channels in the form (@sccc). |
If <ch_list> is omitted, this command applies to the internal DMM. |
|
* Using ITS-90 software conversions. |

Remarks
If you omit the optional <ch_list> parameter, the configuration applies to the internal DMM, independent of any channels or a scan list (any existing scan list is not redefined). An error is generated if the internal DMM is not installed or is disabled.
Thermocouple measurements require a reference junction temperature (see [SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction:TYPE command). For the reference junction temperature, you can use an internal measurement on the module's terminal block (34921A only), an external thermistor or RTD measurement, or a known fixed junction temperature. By default, a fixed reference junction temperature of 0.0
°C is used. The instrument sets the thermocouple type to "J" after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the setting.
Return Format
The query command returns "B", "E", "J", "K", "N", "R", "S", or "T" for each channel specified. Multiple responses are separated by commas.
Examples
The following command selects T-Type thermocouples on channels 3 and 13 in slot 1.
TEMP:TRAN:TC:TYPE T,(@1003,1013)
The following query returns the thermocouple type selections on channels 3 and 13 in slot 1.
TEMP:TRAN:TC:TYPE? (@1003,1013)
Typical Response: T,T
