Damping helps the transmitter smooth out small, rapid measurement fluctuations. A damping value 
specifies the period of time, in seconds, over which the process variable value will change to reflect 
63% of the change in the actual process. 

•

A high damping value makes the output appear to be smoother because the output must change 
slowly.

•

A low damping value makes the output appear to be more erratic because the output changes 
more quickly.

Damping can be configured for flow, density, and temperature (see Sections 4.3.2, 4.7.3, and 4.8.2.).

When you specify a new damping value, it is automatically rounded down to the nearest valid 
damping value. Valid damping values are listed in Table 4-8. 

Before setting the damping values, review the following sections for information on how the damping 
values interact with other transmitter measurements and parameters.
