[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
{ON|1|OFF|0}. Default: OFF.
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
When automatic reference selection is ON, the first measurement made is used as the null value for all
l
subsequent measurements.[SENSe:]VOLTage:{AC|DC}:NULL:VALue
null value selection will be disabled.
When automatic null value selection is disabled (OFF), the null value is specified
l
{AC|DC}:NULL:VALue.
The instrument enables automatic null value selection when the null function is enabled
l
([SENSe:]VOLTage:{AC|DC}:NULL:STATe
The null function is not available for DC ratio measurements.
