[SENSe:]TEMPerature:NULL[:STATe] {ON|1|OFF|0}
[SENSe:]TEMPerature:NULL[:STATe]?
Enables or disables the null function for temperature measurements.
Parameter Typical Return
{ON|1|OFF|0}, default OFF 0(OFF)or1(ON)
Configure 4-wire RTD measurements, using the null function to subtract 25°. Make and read two measurements:
CONF:TEMP RTD
TEMP:NULL:STAT ON;VAL 25
SAMP:COUN 2
READ?
Typical Response: +1.04530000E+00,+1.04570000E+00
l Enabling the scaling function also enables automatic null value selection ([SENSe:]
TEMPerature:NULL:VALue:AUTO ON).
l To set a fixed null value, use this command: [SENSe:]TEMPerature:NULL:VALue.
l The instrument disables the null function after a Factory Reset (*RST), Instrument Preset (SYSTem:PRESet), or
CONFigure function.
[SENSe:]TEMPerature:NULL:VALue {<value>|MIN|MAX|DEF}
[SENSe:]TEMPerature:NULL:VALue? [{MIN|MAX|DEF}]
Stores a null value for temperature measurements.
Parameter Typical Return
-1.0E15 to +1.0E15, default 0 +2.50000000E+01
Configure 4-wire RTD measurements, using the null function to subtract 25°. Make and read two measurements:
CONF:TEMP RTD
TEMP:NULL:STAT ON;VAL 25
SAMP:COUN 2
READ?
Typical Response: +1.04530000E+00,+1.04570000E+00
l Specifying a null value disables automatic null value selection ([SENSe:]TEMPerature:NULL:VALue:AUTO OFF).
l To use the null value, the null state must be on ([SENSe:]TEMPerature:NULL:STATe ON).
l This parameter is set to its default value after a Factory Reset (*RST), Instrument Preset (SYSTem:PRESet), or
CONFigure function.
