[SENSe:]TEMPerature:ZERO:AUTO
Syntax
[SENSe:]TEMPerature:ZERO:AUTO <state>
This command disables or enables the autozero mode for temperature
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 prevents offset voltages
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.
[SENSe:]TEMPerature:ZERO:AUTO?
This command queries the autozero mode for temperature measurements.
Parameter
Remarks
– The autozero mode is set indirectly when you set the resolution and integration
time using the
CONF
or
MEAS?
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}
OFF or 0: Disables the autozero mode
ON or 1: Enables the autozero mode OFF
