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. In the
2051 Wireless pressure transmitter, damping only takes effect when the device is placed in high
power refresh mode and during calibration. In normal power mode, the effective damping is 0.
Note that when the device is in high power refresh mode, battery power will be depleted rapidly.
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 25.6 seconds.
