Syntax

[SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction {<temperature>|MIN|MAX|DEF} [, (@<ch_list>)]

[SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction? [{(@<ch_list>)|MIN|MAX}]

Description

This command sets the fixed reference junction temperature in degrees Celsius for thermocouple measurements on the specified channels. If you omit the optional <ch_list> parameter, this command applies to the internal DMM, independent of any channels or a scan list.

Used With:

• 34921A Armature Multiplexer (with optional 34921T Terminal Block)

• 34922A Armature Multiplexer

• 34923A Reed Multiplexer (differential mode only)

• 34924A Reed Multiplexer

Parameters

Name	Type	Range of Values	Default Value
<temperature>	Discrete	Any temperature between -20 °C and +80 °C. MIN = -20 °C, MAX = +80 °C	0.0 °C
<ch_list>	Numeric	One or more channels in the form (@sccc).	If <ch_list> is omitted, this command applies to the internal DMM.

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 directed at the internal DMM (i.e., no <ch_list> specified) require that a fixed reference junction temperature be used (see [SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction:TYPE command).

• For this command, you must always specify the temperature in degrees Celsius regardless of the temperature units currently selected (see UNIT:TEMPerature command).

• The instrument sets the thermocouple junction to 0 °C 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 the fixed reference junction temperature in the form "+0.00000000E+00" for each channel specified (always in degrees Celsius). Multiple responses are separated by commas.

Examples

The following command sets the fixed reference junction temperature to 20 °C on channels 3 and 13 in slot 1.

TEMP:TRAN:TC:RJUN 20.0, (@1003,1013)

The following query reads the fixed reference junction temperature (always in degrees Celsius) on channels 3 and 13 in slot 1.

TEMP:TRAN:TC:RJUN? (@1003,1013)

Typical Response:  +2.00000000E+01,+2.00000000E+01
