[SENSe:]{RESistance|FRESistance}:NULL:VALue:AUTO {ON|1|OFF|0}
[SENSe:]{RESistance|FRESistance}:NULL:VALue:AUTO?
Enables or disables automatic null value selection 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
Make a second set of measurements using automatic null value selection:
RES:NULL:VAL:AUTO ON
READ?
Typical Response: +0.00000000E+00,+0.01420000E+00
l When automatic reference selection is ON, the first measurement made is used as the null value for all
subsequent measurements. [SENSe:]{RESistance|FRESistance}:NULL:VALue is set to this value. Auto-
matic null value selection will be disabled.
l When automatic null value selection is disabled (OFF), the null value is specified by: [SENSe:]
{RESistance|FRESistance}:NULL:VALue.
l The instrument enables automatic null value selection when the null function is enabled ([SENSe:]
{RESistance|FRESistance}:NULL:STATe ON).
l This parameter is set to its default value after a Factory Reset (*RST), Instrument Preset
(SYSTem:PRESet), or CONFigure function.
