Rerange with a Pressure Input Source and the
Local Zero and Span buttons (option D1)
Reranging using the local zero and span adjustments and a pressure source
is a way of reranging the transmitter.
1. Using a pressure source with an accuracy three to ten times the desired
calibrated accuracy, apply a pressure equivalent to the lower range value
to the high side of the transmitter.
2. Push and hold the zero adjustment button for at least two seconds but no
longer than ten seconds.
3. Apply a pressure equivalent to the upper range value to the high side of
the transmitter.
4. Push and hold the span adjustment button for at least two seconds but
no longer than ten seconds.

The Damp command introduces a delay in processing which increases the
response time of the transmitter; smoothing variations in output readings
1, 3, 6
caused by rapid input changes. Determine the appropriate damp setting
based on the necessary response time, signal stability, and other
requirements of the loop dynamics of your system. The damping value of your
device is user selectable from 0 to 60 seconds. The current damping value
can be determined by executing the Field Communicator fast keys or going to
"Configure" in AMS.
