MLS User’s Guide 73

The graph below shows pressure as an example.

Before you enter the values that determine the two points for the

conversion line, you must choose an appropriate display format. The

MLS has six characters available for process variable display; select the

setting with the desired number of decimal places before and after the

decimal point. Use a display format that matches the range and

resolution of the process variable. The display format you choose is

used for the setpoint, alarms, deadband, spread, and proportional band.

The PV (Process Variable) range for the scaled input is between the PV

values that correspond to the -16.6% and 100% input readings. This PV

range deﬁnes the limits for the setpoint and alarms, as shown here.

NOTE

See Linear Scaling Examples section in this manual.
