Configuration
To configure the AO cutoff:
• Using the Communicator, select
Detailed Setup > Config Outputs > Channel Setup >
AO Setup
.
• Using ProLink II, click
ProLink > Configuration > Analog Output.
Note: You cannot configure the AO cutoff with the display.
Enter the AO cutoff value in the measurement unit that is configured for the assigned process variable.
6.2.4 Added damping
A damping value is a period of time, in seconds, over which the process variable value will change to
reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small,
rapid measurement fluctuations:
• 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.
The Added Damping parameter specifies damping that will be applied to the mA output. It affects the
measurement of the process variable assigned to the mA output.
Note: For most applications, the default added damping value is used. Contact Micro Motion
customer support before changing the Added Damping parameter.
Multiple damping parameters
Damping can also be configured for the flow (mass and volume), density, and temperature process
variables (see Sections ). If one of these process variables has been assigned to an mA output, its
damping is set to a non-zero value, and Added Damping is also set to a non-zero value, the effect of
damping the process variable is calculated first, and the added damping calculation is applied to the
result of that calculation. See the following example.
Example
Configuration:
• mA output process variable: Mass flow
• AO Cutoff: 15 g/sec
• Mass Flow Cutoff: 10 g/sec
As a result, if the mass flow rate drops below 15 g/sec, the mA output
will report zero flow.
