Syntax

[SENSe:]RESistance:OCOMpensated <mode> [, (@<ch_list>)]

[SENSe:]RESistance:OCOMpensated? [(@<ch_list>)]

Description

Offset compensation removes the effects of any dc voltages in the circuit being measured. The technique involves taking the difference between two resistance measurements on the specified channels, one with the current source turned on and one with the current source turned off. 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 through 34925A Multiplexer Modules

Parameters

Remarks

• Once enabled, offset compensation is applied to both 2-wire and 4-wire resistance measurements on the specified channels.

• 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.

• Since 2-wire and 4-wire resistance are related functions, changing a measurement parameter for one function will also change the corresponding parameter for the other function (see [SENSe:]FRESistance:OCOMpensated command).

• The CONFigure and MEASure? commands automatically disable offset compensation.  

• The instrument disables offset compensation 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 "0" (OFF) or "1" (ON) for each channel specified. Multiple responses are separated by commas.

Examples

The following command enables offset compensation on channels 3 and 13 in slot 1.

RES:OCOM ON,(@1003,1013)

The following query returns the offset compensation settings on channels 3 and 13 in slot 1.

RES:OCOM? (@1003,1013)

Typical Response:  1,1
