Syntax

[SENSe:]TEMPerature:TRANsducer:TYPE {TCouple|RTD|FRTD|THERmistor|DEF}[,(@<ch_list>)]

[SENSe:]TEMPerature:TRANsducer:TYPE? [(@<ch_list>)]

Description

This command selects the temperature transducer probe type to use for measurements on the specified channels.

The following table shows which temperature transducers are supported by each of the multiplexer modules.

Module	Thermocouple	RTD 2-Wire	RTD 4-Wire	Thermistor
34901A Armature Multiplexer	Yes	Yes	Yes	Yes
34902A Reed Multiplexer	Yes	Yes	Yes	Yes
34908A Armature Multiplexer (1-Wire)	Not Recommended¹	Yes	No¹	Yes

1With a one-wire multiplexer, even very small ground currents can introduce substantial measurement error.

Parameters

Name Type Range of Values Default Value

<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.

Name	Type	Range of Values	Default Value
<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

Choosing the type DEF is equivalent to choosing TC.
For 4-wire resistance measurements, the instrument automatically pairs channel n in Bank 1 with channel n+10 in Bank 2 (34901A) or n+8 (34902A) to provide the source and sense connections. For example, make the source connections to the HI and LO terminals on channel 02 in Bank 1 and the sense connections to the HI and LO terminals on channel 12 (34901A) or 10 (34902A) in Bank 2.Specify the paired channel in Bank 1 (source) as the <ch_list> channel (channels in Bank 2 are not allowed in the <ch_list>).
The instrument selects thermocouple as the probe type 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 TC, RTD, FRTD, or THER. Multiple channels are separated by commas.

Examples

The following command sets the temperature transducer type to FRTD for the channels shown.

TEMP:TRAN:TYPE FRTD,(@201:205)

The following query returns the temperature transducer type for the channels shown.

TEMP:TRAN:TYPE? (@201:208)

Typical Response: FRTD,FRTD,FRTD,FRTD,FRTD,RTD,TC,THER
