[SENSe:]VOLTage:{AC|DC}:NULL:VALue {<value>|MIN|MAX|DEF}
[SENSe:]VOLTage:{AC|DC}:NULL:VALue? [{MIN|MAX|DEF}]
Stores a null value for 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
-1200 to +1200 V. Default: 0. +1.00000000E-02
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 Specifying a null value disables automatic null value selection ([SENSe:]VOLTage:
{AC|DC}:NULL:VALue:AUTO OFF).
l To use the null value, the null state must be on ([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.
