Description Enable or disable the offset compensation function for the 2-wire or 4-wire resistance
measurements on the specified channels.

<state>
Bool
{OFF|0|ON|1}
OFF
<ch_list>
Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the
module in Slot1;
(@101:103,301): channel 01 through 03 on
the module in Slot1 and channel 01 on the
module in Slot3.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  MC3164 and MC3264 do not support the 4-wire resistance measurement function.
 For the 4-wire resistance measurement function, channel n is paired with channel
n+16 (MC3132 and MC3232, wherein the range of n is from 1 to 16) or n+10 (MC3324
and MC3120, wherein the range of n is from 1 to 10) automatically. Channel n is used
to connect the source terminal of the DMM and channel n+16 or channel n+10 is used
to connect the sense terminal of the DMM. The paired channels cannot be configured.
 The offset compensation removes the effects of any DC offset of the measurement
lead on the measurement results.
 Turning the offset compensation on will double the measurement time.
 The
CONFigure:FRESistance (CONFigure:RESistance) or MEASure:FRESistance?
(
MEASure:RESistance?) command automatically disables the offset compensation.
 The offset compensation and auto zero are mutually exclusive. After enabling the
offset compensation, the auto zero will be disabled automatically.
 The instrument disables the offset compensation after a Factory Reset (send the
*RST
command). An Instrument Preset (send the
SYSTem:PRESet command) or Card Reset
(send the
SYSTem:CPON command) does not affect the current status of the offset
compensation.
Return
Format
The query returns 0 (OFF) or 1 (ON). Multiple return values are separated by commas.
Example
FRES:OCOM ON,(@201,212)
FRES:OCOM? (@201,212)
The query returns 1,1.
You can replace FRES with RES to enable or disable the offset compensation function for
the 2-wire resistance measurements on the specified channels.
