l PCT performs a percent change operation. The result is the percent change of the measurement from
the reference value:
Result = ((Measurement – Reference) / Reference) * 100
For the PCT function, the reference value can be automatically selected using the first measurement
as the reference value (see CALCulate:SCALe:REFerence:AUTO), or it can be specified by CALCu-
late:SCALe:REFerence. % scaling applies to all measurement functions except Ratio, Continuity, and
Diode.
l SCALe performs an Mx-B operation. The result is the measurement multiplied by the gain value M
(CALCulate:SCALe:GAIN) minus the offset value B (CALCulate:SCALe:OFFSet). Mx-B scaling applies to
all measurement functions except Ratio, Continuity, and Diode.
l Scaling function results must be in the range of -1.0E+24 to -1.0E-24, or +1.0E-24 to 1.0E+24. Res-
ults outside these limits will be replaced with -9.9E37 (negative infinity), 0, or 9.9E37 (positive infinity).
l
You must execute CALCulate:SCALe:FUNCtion before executing CALCulate:SCALe[:STATe], otherwise
an incompatibility error will be generated.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
l Scaling is set to OFF when you change measurement functions (for example, changing from DCV to
ACV). You must re-enable scaling after changing measurement functions.
CALCulate:SCALe:GAIN {<gain>|MIN|MAX|DEF}
CALCulate:SCALe:GAIN? [{MIN|MAX|DEF}]
Stores a gain value M for the scaling function in CALCulate:SCALe:FUNCtion.
Parameter Typical Return
-1.0E+15 to -1.0E-15, 0.0, +1.0E-15 to 1.0E+15. Default: 1.0. +1.00000000E+02
Enable Mx-B scaling with a gain of 100 and an offset of 5.

l Applies only to the 34465A and 34470A.
l The instrument sets the gain value to 0.0 after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
