8.3.1 Configure Frequency Output Source
Display Menu > Configuration > Inputs/Outputs > Channel x > I/O Settings > Source

Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > Frequency Output x
Frequency Output Source specifies the process variable that is reported by the Frequency Output.
Prerequisites
• If you plan to configure the output to report volume flow, ensure that you have set Volume Flow Type as
desired: Liquid or Gas Standard Volume.
• If you plan to configure an output to report a concentration measurement process variable, ensure that
the concentration measurement application is configured so that the desired variable is available.
Procedure
Set Frequency Output Source as desired.
Defaults:
• Frequency Output 1: Mass Flow Rate
Postrequisites
If you change the configuration of Frequency Output Source, verify the Frequency Output scaling. The
transmitter automatically loads the most recent values for the scaling parameters, and they may not be
appropriate for your application.
Options for Frequency Output Source
The transmitter provides a basic set of options for Frequency Output Source, plus several application-specific
options. Different communications tools may use different labels for the options.
8.3.2 Configure Frequency Output Scaling

Frequency output scaling defines the relationship between Frequency Output Source and the pulse of the
Frequency Output. Scale the Frequency Output to provide the data in the form required by your frequency
receiving device.
Procedure
1. Set Frequency Output Scaling Method.

Description
Frequency=Flow (default) Frequency calculated from flow rate
