Signal Scaling
If the signals being trended are internal signals (AcDcEx), the values defined allow
signals to use engineering units instead of raw (count) values. If they are external
signals (controller), these fields are grayed out and the scaling is defined in the
database, and the dialog serves a display-only purpose.
