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}
