The OCOMP command enables or disables the offset compensated ohms function.

The control parameter choices are:

Parameter Equiv.
OFF 0
ON 1
Power-on control = OFF.
Default control = ON.
•
With offset compensation enabled, the multimeter measures the external offset
voltage (with the ohms current source shut off) before each resistance reading
and subtracts the offset from the following reading. This prevents the offset
voltage from affecting the resistance reading, but it doubles the time required
per reading.
•
You can use offset compensated ohms on both 2-wire and 4-wire resistance
measurements. When you have offset compensation enabled and change from
ohms to some other measurement function (DCV, ACV, etc.), offset
compensation is temporarily disabled. When you return to 2-wire or 4-wire
ohms, however, offset compensation is once again enabled.
•
The multimeter can only perform offset compensation on the 10
W
through100k ranges. If OCOMP is enabled when using the 1M
W
1G ranges, readings are made without offset compensation.
•
Query Command. The OCOMP? query command returns the present offset
compensation mode. Refer to "Query Commands" near the front of this chapter
for more information.
