CALCulate:SCALe:OFFSet:NULL [(@<ch_list>)]
Makes an immediate null measurement on the specified channels and stores it as the offset (B) for subsequent meas-
urements. This allows you to adjust for voltage or resistive offsets through your wiring to the point of the meas-
urement.
Parameter Typical return
(none) (none)
Sets an immediate null measurement on channels 105 through 108:
CALC:SCAL:OFFS:NULL (@105:108)
CALCulate:SCALe:REFerence {<reference> | MIN | MAX | DEF} [, (@<ch_list>)]
CALCulate:SCALe:REFerence? [{(@<ch_list>) | MIN | MAX | DEF}]
Stores a reference value for the PCT function in CALCulate:SCALe:FUNCtion.
Parameter Typical return
<reference>
MIN: -1.0E+15 to -1.0E-15
DEF: 0.0
MAX: +1.0E-15 to 1.0E+15
+3.00000000E+02
Sets PCT scaling with a 100 V reference:
CALC:SCAL:REF 100
CALC:SCAL:FUNC PCT
CALC:SCAL:STAT ON
– Specifying a reference value disables automatic reference selection
(CALCulate: SCALe:REFerence:AUTO OFF).
– The instrument sets the reference value to 0.0 with automatic reference selection enabled after a Factory Reset
(*RST), an Instrument Preset (SYSTem:PRESet), or a change in measurement function.
