[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: +1.0400,+1.0400
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.
