SENSe1 subsystem
The Sense1 subsystem commands configure and control the measurement functions of the
Model 2450.
Many of these commands are set for a specific function (current, voltage, or resistance). For example,
you can program a range setting for each function. The settings are saved with that function.

Usage
[:SENSe[1]]:AZERo:ONCE
Details
This command forces a refresh of the reference and zero measurements that are used for the present aperture
setting.
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.
Example
AZER:ONCE
Do a once time refresh of the reference and zero
measurements.
