Procedure
Set Frequency Output Process Variable as desired.
The default setting is Mass Flow Rate.
Options for Frequency Output Process Variable
The transmitter provides a basic set of options for Frequency Output Process Variable, plus
several application-specific options. Different communications tools may use different
labels for the options.

Overview
Frequency Output Polarity controls how the output indicates the ON (active) state. The default
value, Active High, is appropriate for most applications. Active Low may be required by
applications that use low-frequency signals.
