Interaction between Added Damping and process variable
damping
When mA Output Process Variable is set to a flow variable, density, or temperature, Added
Damping interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple
damping parameters are applicable, the effect of damping the process variable is
calculated first, and the added damping calculation is applied to the result of that
calculation.
Example: Damping interaction
Configuration:
Flow Damping = 1 second
mA Output Process Variable = Mass Flow Rate
Added Damping = 2 seconds
Result: A change in the mass flow rate will be reflected in the mA output over a time period
that is greater than 3 seconds. The exact time period is calculated by the transmitter
according to internal algorithms which are not configurable.

Overview
mA Output Fault Action controls the behavior of the mA output if the transmitter encounters
an internal fault condition.
