Overview
Damping controls the amount of damping that will be applied to the core process variable:
specific gravity, molecular weight, or relative density.
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
