Postrequisites
CAUTION
If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action to None. If you do not, the output will not report actual process data, and
this may result in measurement errors or unintended consequences for your process.
Options for mA Output Fault Action and mA Output Fault Level
Option
Upscale
Downscale (default)
Internal Zero
None

6.2 Configure the Frequency Output

The Frequency Output is used to report a process variable for mass or volume flow. Frequency Output does
not report density, temperature, or differential pressure. The Frequency Output parameters control how the
process variable is reported.
Important
Whenever you change a Frequency Output parameter, verify all other Frequency Output parameters before
returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored
values, and these values may not be appropriate for your application.
6.2.1 Configure Frequency Output Power Source

Use Frequency Output Power Source to set the power source for the Frequency Output. The power
configuration must match the wiring for the Frequency Output.
Procedure
Set Frequency Output Power Source as desired.
