[SENSe:]CURRent:{AC|DC}:NULL:VALue:AUTO {ON|1|OFF|0}
[SENSe:]CURRent:{AC|DC}:NULL:VALue:AUTO?
Enables or disables automatic null value selection for AC or DC current measurements.
This parameter setting is not shared between AC and DC measurements. The parameters are independent for
AC and DC measurements.
On the 34461A, 34465A, or 34470A, use the
which current terminals to use for the measurement.
Parameter
{ON|1|OFF|0}. Default: ON.
Configure AC current measurements, using the null function to subtract 100 mA from the measurements.
Then make two measurements and send them to the instrument's output buffer:
CONF:CURR:AC
CURR:AC:NULL:STAT ON;VAL 100 mA
SAMP:COUN 2
READ?
Typical Response: +1.04530000E+00,+1.04570000E+00
Make a second set of measurements using automatic null value selection:
CURR: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
l
all subsequent measurements.
null value selection will be disabled.
When automatic null value selection is disabled (OFF), the null value is specified by:
l
[SENSe:]CURRent:{AC|DC}:NULL:VALue.
The instrument enables automatic null value selection when the null function is enabled
l
([SENSe:]CURRent:{AC|DC}:NULL:STATe
This parameter is set to its default value after a Factory Reset (*RST), Instrument Preset
l
(SYSTem:PRESet), or CONFigure function.
