The measurement function to which this setting applies:
 Concurrent: CONCurrent[:DC]
 Current: CURRent[:DC]
 Voltage: VOLTage[:DC]
Details
This command triggers the Series 2280 to make a new measurement for the selected function. This
measurement is then stored as the new relative offset level setting.
When you send this command, the measurement is made without applying any filter operations, even
if they are set. It is as if these settings are disabled.
After executing this command, you can use the following command to see the last relative level value
that was acquired or that was set.
:SENSe[n]:<function>:REFerence?
If an error occurs during the measurement, the relative offset level remains at the last valid setting.
This command only works if the instrument is on the specified function. For example, if the
instrument is on the voltage function, the only valid acquire command is SENS:VOLT:REF:ACQ.
Also, if the acquired measurement has caused an overflow condition or the instrument is waiting for
the trigger to start measurements, you will see error -200, "Execution error" when you send this
command.
Example
:SENS:FUNC "VOLT"
:SENS:VOLT:REF:STAT ON
:SENS:VOLT:REF:ACQ
:SENS:VOLT:REF?
Switch to voltage measurements.
Turn relative offset on.
Acquire a relative offset value for voltage measurements.
Query for the offset value.
