Details
This command forces a refresh of the reference and zero measurements that are used for the present
aperture setting for the selected function.
When autozero is set to off, the instrument may gradually drift out of specification. To minimize the
drift, you can send the once command to make a reference and zero measurement immediately
before a test sequence.
If the NPLC setting is less than 0.2 PLC, sending autozero once can result in delay of more than a
second.
Example
dmm.measure.autozero.once()
Do a one-time refresh of the reference and zero
measurements.
