[SENSe:]CURRent:{AC|DC}:NULL[:STATe] {ON|1|OFF|0}
[SENSe:]CURRent:{AC|DC}:NULL[:STATe]?
Enables or disables the null function 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
[SENSe:]CURRent:{AC|DC}:TERMinals
command to spe-
cify which current terminals to use for the measurement.
Parameter
Typical Return
{ON|1|OFF|0}. Default: OFF.
0 (OFF) or 1 (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: +1.0400,+1.0400
l
Enabling the scaling function also enables automatic null value selection (
).
l
To set a fixed null value, use:
[SENSe:]CURRent:{AC|DC}:NULL:VALue
l
The instrument disables the null function after a Factory Reset (
), Instrument Preset
(
), or CONFigure function.
