A.3.7 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.
