[SENSe:]VOLTage:{AC|DC}:NULL[:STATe] {ON|1|OFF|0}
[SENSe:]VOLTage:{AC|DC}:NULL[:STATe]?
Enables or disables the null function for AC 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
l Enabling the scaling function also enables automatic null value selection ([SENSe:]VOLTage:
{AC|DC}:NULL:VALue:AUTO ON).
l To set a fixed null value, use: [SENSe:]VOLTage:{AC|DC}:NULL:VALue.
l The null function is not available for DC ratio measurements.
l The instrument disables the null function after a Factory Reset (*RST), Instrument Preset
(SYSTem:PRESet), or CONFigure function.
