Restoring Instrument State
The U2741A automatically saves the last configuration
whenever a power- down event occurs and restores to the
last power- down state when you turn on the instrument.
Autozero
When autozero is enabled, the digital multimeter internally
disconnects the input signal following each measurement,
and takes a zero reading. It then subtracts the zero reading
from the preceding reading. This prevents offset voltages
present on the digital multimeter’s input circuitry from
affecting measurement accuracy.
This is applicable to dc voltage, dc current, two- wire ohms
and temperature measurements only.
SCPI Commands
The following commands are used to set the autozero:
VOLTage:ZERO:AUTO {OFF|ON}
CURRent:ZERO:AUTO {OFF|ON}
RESistance:ZERO:AUTO {OFF|ON}
TEMPerature:ZERO:AUTO {OFF|ON}
