2 Instruction Descriptions
The following conversion is used.
Y1−Y0
(Sclln − X0) + Y0 + SclOfs
Out =
X1−X0
Notation Example
The following notation example scales an input value of 2,500 from an input range of 0 to 4,000 to an
output range of 0% to 100%. An offset of 5% is added to the output value.
The following values are used: SclIn = REAL#2500, X0 = REAL#0, X1 = REAL#4000, Y0 = REAL#0,
Y1 = REAL#100, and SclOfs = REAL#5.
The value of Out will be REAL#67.5.

X0
An input value of 2,500 is scaled to 62.5 for an input range of 0 to 4,000
and an output range of 0 to 100. When an offset of 5 is added, Out
becomes REAL#67.5.
