Syntax
[SENSe:]TEMPerature:TRANsducer:RTD:TYPE <type> [, (@<ch_list>)]
[SENSe:]TEMPerature:TRANsducer:RTD:TYPE? [(@<ch_list>)]
Description
This command selects the RTD type for 2-wire temperature 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
34922A Armature Multiplexer
34923A Reed Multiplexer
34924A Reed Multiplexer

<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 (85) and IPTS-68 (91) 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.
The instrument supports RTDs with Alpha = 0.00385 (DIN/IEC 751) using ITS-90 software conversions or Alpha = 0.00391 using IPTS-68 software conversions.
"PT100" is a special label that is sometimes used to refer to an RTD with Alpha = 0.00385 and Ro = 100Ω.
The instrument sets the RTD type to "85" 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 "+85" or "+91" for each channel specified. Multiple responses are separated by commas.
Examples
The following command selects Type 85 RTDs on channels 3 and 13 in slot 1.
TEMP:TRAN:RTD:TYPE 91,(@1003,1013)
The following query returns the RTD type selections on channels 3 and 13 in slot 1.
TEMP:TRAN:RTD:TYPE? (@1003,1013)
Typical Response: +91,+91
