[SENSe:]RESistance:ZERO:AUTO
Syntax
[SENSe:]RESistance:ZERO:AUTO <state>
[SENSe:]RESistance:ZERO:AUTO?
Description
This command disables or enables the autozero mode for resistance
measurements.
– When autozero is
ON
(default), the U2741A internally disconnects the input
signal following each measurement, and takes a zero reading. It then subtracts
the zero reading from the preceding reading. This removes offset variations
present on the U2741A input circuitry from affecting measurement accuracy.
– When autozero is
OFF
, the U2741A uses the last measured zero reading and
subtracts it from each measurement. It takes a new zero reading each time you
change the function, range, or integration time.
Parameter
Remarks
– This command does not affect four-wire resistance measurements. All
four-wire measurements are made with autozero
ON
, regardless of the state set
or returned by this command or query.
– The autozero mode is set indirectly when you set the resolution and integration
time using the
CONFigure
or
MEASure
commands. Autozero is automatically
turned off when you select an integration time less than 1 PLC with these
commands.
– The autozero mode is reset to the default (
OFF
) at power up, or after a factory
reset (
*RST
command) or an Instrument Preset (
SYST:PRES
command).
Item Type Range of values Default value
state Boolean {OFF|0|ON|1}
