To set autozero on or off using SCPI commands:
:SYSTem:AZERo[:STATe] ON
:SYSTem:AZERo[:STATe] OFF
If autozero is enabled, all functions make internal reference measurements. If disabled, no functions
make internal reference measurements.
When you perform a fast low-current measurement, you can disable the autozero for better
measurement speed. However, if you perform a high-current measurement, enable autozero to
reduce the effect of temperature on the readings.
Displayed digits
You can set the number of digits that are displayed for measurement readings on the front panel. You
can display 4.5, 5.5, or 6.5 digits. The default is 6.5.

readings that are returned from a remote command.
