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:
- 34901A 20 Channel Multiplexer (2/4-wire) Module
- 34902A 16 Channel Multiplexer (2/4-wire) Module
- 34908A 40 Channel Single-Ended Multiplexer Module
Parameters
Name Type Range of Values Default Value <type> Discrete {B|E|J|K|N|R|S|T} This is a required parameter. <ch_list> Channel List One or more channels, as shown:
(@310) - channel 10 on the module in slot 300.
(@305:310) - channels 05 through 10 on the module in slot 300.
(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.
If you omit the optional <ch_list> parameter, this command applies to the currently defined scan list.
Remarks
- 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 (34901A 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 returns the thermocouple type as a quoted letter for each channel in the list. Multiple channels are separated by commas.
Examples
The following command sets the thermocouple to J for the channels shown.
TEMP:TRAN:TCouple:TYPE J,(@201:204)
The following query returns the thermocouple type for the channels shown.
TEMP:TRAN:TC:TYPE? (@101,103,202:204,301)
Typical Response: B,R,J,J,J,K
