[SENSe:]{RESistance|FRESistance}:NULL[:STATe] {ON|1|OFF|0}
[SENSe:]{RESistance|FRESistance}:NULL[:STATe]?
Enables or disables the null function for all resistance measurements.
This parameter is common to 2-wire and 4-wire resistance measurements. Using the FRESistance version
of this command or query is identical to using the RESistance version.
Parameter Typical Return
{ON|1|OFF|0}. Default: OFF. 0(OFF)or1(ON)
Configure 2-wire resistance measurements, using the null function to remove 100 mΩ of wiring resistance.
Make and read two measurements:
CONF:RES
RES:NULL:STAT ON;VAL .1
SAMP:COUN 2
READ?
Typical Response: +1.04530000E+02,+1.04570000E+02
l Enabling the scaling function also enables automatic null value selection (SENSe:
{RESistance|FRESistance}:NULL:VALue:AUTO ON).
l To set a fixed null value, use: [SENSe:]{RESistance|FRESistance}:NULL:VALue.
l The instrument disables the null function after a Factory Reset (*RST), Instrument Preset
(SYSTem:PRESet), or CONFigure function.
