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
. % 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
(
). 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 (
) or Instrument 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.
