[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: +1.0402,+1.0402
Make a second set of measurements using automatic null value selection:
RES:NULL:VAL:AUTO ON
READ?
Typical Response: +0.0000,+0.0100
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:
{RESistance|FRESistance}:NULL:VALue
l
The instrument enables automatic null value selection when the null function is enabled (
{RESistance|FRESistance}:NULL:STATe ON
).
l
This parameter is set to its default value after a Factory Reset (
), Instrument Preset
(
), or CONFigure function.
