[SENSe:]RESistance:ZERO:AUTO {OFF|ON|ONCE}
[SENSe:]RESistance:ZERO:AUTO?
Disables or enables the autozero mode for 2-wire resistance measurements.
ON (default): the DMM internally measures the offset following each measurement. It then subtracts
l
that measurement from the preceding reading. This prevents offset voltages present on the DMM's
input circuitry from affecting measurement accuracy.
OFF: the instrument uses the last measured zero measurement and subtracts it from each meas-
l
urement. It takes a new zero measurement each time you change the function, range or integration
time.
ONCE: the instrument takes one zero measurement and sets autozero OFF. The zero measurement
l
taken is used for all subsequent measurements until the next change to the function, range or integ-
ration time. If the specified integration time is less than 1 PLC, the zero measurement is taken at 1
PLC to optimize noise rejection. Subsequent measurements are taken at the specified fast (< 1 PLC)
integration time.
Parameter
{OFF|ON|ONCE}
Configure 2-wire resistance measurements and perform an immediate autozero. Make and read two meas-
urements:
CONF:RES 1E4

Typical Response: +1.04530000E+03,+1.04570000E+03
Does not affect 4-wire resistance measurements, which are always made with autozero ON.
l
The autozero mode is set indirectly when you set the resolution and integration time using
l
ure:{RESistance|FRESistance}
turned OFF when you select an integration time less than 1 PLC with these commands.
This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
l
(SYSTem:PRESet).
