[SENSe:]VOLTage:{AC|DC}:NULL:VALue:AUTO {ON|1|OFF|0}
[SENSe:]VOLTage:{AC|DC}:NULL:VALue:AUTO?
Enables or disables automatic null value selection for AC voltage or DC voltage measurements.
This parameter setting is not shared between AC and DCmeasurements. The parameters are independent
for AC and DCmeasurements.
Parameter Typical Return
{ON|1|OFF|0}. Default: OFF. 0(OFF)or1(ON)
Configure AC voltage measurements, using the null function to subtract 100 mV from the measurements.
Make and read two measurements:
CONF:VOLT:AC
VOLT:AC:NULL:STAT ON;VAL 100 mV
SAMP:COUN 2
READ?
Typical Response: +1.04530000E+00,+1.04570000E+00
Make a second set of measurements using automatic null value selection:
VOLT:AC:NULL:VAL:AUTO ON
READ?
Typical Response: +0.00000000E+00,+0.01420000E+00
l When automatic reference selection is ON, the first measurement made is used as the null value for all
subsequent measurements.[SENSe:]VOLTage:{AC|DC}:NULL:VALue is set to this value. Automatic
null value selection will be disabled.
l When automatic null value selection is disabled (OFF), the null value is specified by:[SENSe:]VOLTage:
{AC|DC}:NULL:VALue.
l The instrument enables automatic null value selection when the null function is enabled
([SENSe:]VOLTage:{AC|DC}:NULL:STATe ON).
l The null function is not available for DC ratio measurements.
l This parameter is set to its default value after a Factory Reset (*RST), Instrument Preset
(SYSTem:PRESet), or CONFigure function.
