Command Summary

[SENSe:]CAPacitance:NULL[:STATe]

[SENSe:]CAPacitance:NULL:VALue

[SENSe:]CAPacitance:NULL:VALue:AUTO

[SENSe:]CAPacitance:RANGe:AUTO

[SENSe:]CAPacitance:RANGe

[SENSe:]CAPacitance:SECondary

[SENSe:]CAPacitance:NULL[:STATe] {ON|1|OFF|0}
[SENSe:]CAPacitance:NULL[:STATe]?

Turns the null function on or off 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 measurements 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

[SENSe:]CAPacitance:NULL:VALue {<value>|MIN|MAX|DEF}
[SENSe:]CAPacitance:NULL:VALue? [{MIN|MAX|DEF}]

Stores a null value for capacitance measurements. The null value is subtracted from each sample if the null state is turned on.

Parameter Typical Return
<value> -120 to +120 µF. Default: 0. -1.20000000E-04

Configure capacitance measurements, turn null function on. Make two measurements and send them to the instrument's output buffer:

CONF:CAP AUTO
CAP:NULL ON
CAP:NULL:VAL 1.2E-12

READ?

Typical Response: +3.01963841E-10,+3.01566277E-10

[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
