Details
This command triggers the Model 2450 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 math, limit test, or filter settings,
even if they are set. It is a reading as if these settings are disabled.
After executing this command, you can use the [:SENSe[1]]:<function>:RELative command to see the
last relative level value that was acquired or that was set.
If an error occurs during the measurement, the relative offset level remains at the last valid setting.
Example
FUNC "RES"
RES:REL:ACQ
RES:REL?
RES:REL:STAT ON
Switch to resistance measurements. Acquire
a relative offset value for resistance
measurements. Query for the offset value.
Turn relative offset on.
