8 Scaling Measured Values
User scaling serves to adjust the process values.
When user scaling is used, the required accuracy of the process value resolution
is changed, but not fundamentally limited.
User scaling is optional.
The values for "Gain" and "Offset" are required in order to perform user scaling.
The scaling gain is the gain factor. The scaling offset is the offset on the y axis.
When these two values are input, the result is a scaled process value.
The following general scaling equation applies:
The variables have the following meanings:

The y1 value (unscaled process value) serves as the input value for the user
scaling. If user scaling is switched off, the y1 value is carried over unchanged to
y2.
