1. Select Next after the control loop is set to manual.
2. From the “Apply Values” menu, follow the on-line instructions to
configure lower and upper range values.
3. Select Exit to leave the “Apply Values” screen.
4. Select Next to acknowledge the loop can be returned to automatic
control.
5. Select Finish to acknowledge the method is complete.
Damping
The damping command introduces a delay in processing which increases the
response time of the transmitter; smoothing variations in output readings
caused by rapid input changes. Determine the appropriate damping setting
based on the necessary response time, signal stability, and other
requirements of the of loop dynamics of your system. The default damping
value is 0.4 seconds and is user-selectable from 0 to 60 seconds.

The meter features a two-line display and a 0-100% scaled bar graph. The
first line of five digits displays the actual value, the second line of six
characters displays engineering units and “Error” displays on both lines when
the transmitter is in alarm. The LCD display can also display diagnostic
messages.
