Watlow Anafaze 55
The PV (Process Variable) range for the scaled input is
between the PV values that correspond to the 0% and 100%
input readings. For the pulse input, it is between the 0Hz
and 2000Hz readings. This PV range defines the limits for
the setpoint and alarms, as shown here.
NOTE! For example linear scaling calculations, see
Chapter 6, Linear Scaling Examples on page 87.
Display Format
This menu lets you select a display format for a linear or
pulse input. Choose a format appropriate for your input
range and accuracy. (You will only see the Display Format
menu if you are editing a linear or pulse input.)
The CAS200 has several available display formats; the
display format you choose determines the default values for
the rest of the linear scaling menus.
