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.
