:ZERO:AUTO?

CALibrate:ZERO:AUTO <
applies to dc voltage, dc current and 2-wire ohms measurements only. 4-wire ohms
and dc voltage ratio measurements automatically enable the autozero mode.

The
ON
parameter enables autozero. This is the default parameter which
causes the multimeter to internally disconnect the input signal following each
measurement and make a zero measurement. The zero reading is subtracted
from the input signal reading to prevent offset voltages present on the
multimeter's input circuitry from affecting measurement accuracy.
•
The
parameter disables autozero. In this mode the multimeter takes one
OFF
zero measurement and subtracts it from all subsequent input signal
measurements prior to a change in function, range or integration time. A new
zero measurement is made following a change in function, range or integration
time. This mode increases measurement speed because a zero measurement is
not made for each input signal measurement.
•
Autozero
ONCE
issues an immediate zero measurement and can be used to get
an update on the zero measurement for a specific input signal measurement.
This helps to increase measurement speed since you update the zero reading
without making zero measurements for every measurement.
