Valid values for Added Damping
0.0, 0.1, 0.3, 0.75, 1.6, 3.3, 6.5, 13.5, 27.5, 55, 110, 220, 440
Interaction between mA Output Damping and process variable damping
When mA Output Source is set to a flow rate variable, density, or temperature, mA Output 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 mA Output damping
calculation is applied to the result of that calculation.
Damping interaction
Configuration:
• Flow Damping = 1 second
• mA Output Source = Mass Flow Rate
• mA Output 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.

mA Output Fault Action controls the behavior of the mA Output if the transmitter encounters an internal
fault condition.
Note
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement the fault
action until the timeout has elapsed.
Procedure
1. Set mA Output Fault Action to the desired value.
The default setting is Downscale.
Restriction
If Digital Communications Fault Action is set to NAN (not a number), you cannot set mA Output Fault
Action or Frequency Output Fault Action to None. If you try to do this, the transmitter will not accept
the configuration.
2. If you set mA Output Fault Action to Upscale or Downscale, set mA Output Fault Level as desired.
