Integrate the meter with the control system
When you specify a value for
Added Damping
, the transmitter automatically rounds the value down to the
nearest valid value. Valid values are shown in Table 7-3 .

Interaction of damping parameters
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.
t
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.

mA Output Fault Action
controls the behavior of the mA output if the transmitter encounters an internal fault
condition.
Note
If
Last Measured Value 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
.
2.
If you set
mA Output Fault Action
to
Downscale
, set
mA Output Fault Level
as desired.
