Linear Scaling Menus
NOTE
The next four menus appear only for Linear or
Pulse loops.
For all inputs automatic scaling is provided. To set the scaling enter a
high process variable in engineering units and a corresponding high
reading. Then enter a low process variable in engineering units and a
corresponding reading. Using points as near as possible to zero and full
scale is best. After these entries the process variable, the setpoint and
alarms will all be in engineering units.
