Description
This command selects the RTD type for 2-wire (RTD) or 4-wire (FRTD) temperature 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 (RTD only; not FRTD)
Parameters
Name Type Range of Values Default Value <type> Discrete {85|91} 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
- 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 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 returns +85 or +91. Multiple results are separated by commas.
