[SENSe:]CAPacitance:NULL:VALue:AUTO {ON|1|OFF|0}
[SENSe:]CAPacitance:NULL:VALue:AUTO?
Enables or disables automatic null value selection for capacitance measurements.
Parameter
Typical Return
{ON|1|OFF|0}. Default: ON.
0 (OFF) or 1 (ON)
Configure capacitance measurements, turn null function on, use the AUTO null function. Make two meas-
urements and send them to the instrument's output buffer:
CONF:CAP AUTO
CAP:NULL ON
CAP:NULL:VAL:AUTO ON
SAMP:COUN 2
READ?
Typical Response: +3.01963841E-10,+3.01566277E-10
l
When automatic reference selection is ON, the first measurement made is used as the null value for all
subsequent measurements.
[SENSe:]CAPacitance:NULL:VALue
is set to this value. Automatic null
value selection will be disabled.
l
When automatic null value selection is disabled (OFF), the null value is specified by:
l
The instrument enables automatic null value selection when the null function is enabled
(
[SENSe:]CAPacitance:NULL:STATe ON
).
l
This parameter is set to its default value after a Factory Reset (
), Instrument Preset
(
), or CONFigure function.
[SENSe:]CAPacitance:RANGe:AUTO {OFF|ON|ONCE}
[SENSe:]CAPacitance:RANGe:AUTO?
Disables or enables autoranging for capacitance measurements.
Parameter
Typical Return
{OFF|ON|ONCE}. Default: ON.
0 (OFF) or 1 (ON)
Configure capacitance measurements, turn autorange on, turn null function on, use the AUTO null function.
Make two measurements and send them to the instrument's output buffer:
CONF:CAP
CAP:RANG:AUTO ON
CAP:NULL ON
CAP:NULL:VAL:AUTO ON
SAMP:COUN 2
READ?
Typical Response: +3.01963841E-10,+3.01566277E-10
l
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
range. For capacitance measurements only, when autorange is off, the instrument does not report an
