Usage
[:SENSe[1]]:<function>:OCOMpensated <state>
[:SENSe[1]]:<function>:OCOMpensated?
<function>
The measure function:

Current:
CURRent[:DC]

Resistance:
RESistance

Voltage:
VOLTage[:DC]
<state> Disable offset compensation:
OFF
or
0
Enable offset compensation:
ON
or
1
Details
The voltage offsets caused by the presence of thermoelectric EMFs (V
EMF
) can adversely affect
resistance measurement accuracy. To overcome these offset voltages, you can use
offset-compensated ohms.
This feature is only applied to resistance measurements or when
[:SENSe[1]]:CURRent:UNIT
or
[:SENSe[1]]:VOLTage:UNIT
is set to
OHM
.
