8.5.1 Configure Frequency Input Assignment
Display Menu > Configuration > Inputs/Outputs > Channel D > I/O Settings
ProLink III Device Tools > Configuration > I/O > Inputs > Frequency Input
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel D > Frequency Input
Frequency Input Assignment defines the type of data that the transmitter is receiving via the Frequency
Input.
Procedure
1. Set Frequency Input Assignment to the type of data that is being sent to the Frequency Input.
Option Description
Mass Flow Rate The Frequency Input represents mass flow rate.
Volume Flow Rate The Frequency Input represents volume flow rate.
Gas Standard Volume Flow Rate The Frequency Input represents gas standard volume flow rate.
2. Ensure that the transmitter and the external device are using the same measurement unit for the
selected process variable.

8.5.2 Configure Frequency Input scaling
Display
Menu > Configuration > Inputs/Outputs > Channel D > I/O Settings > Scaling Method
ProLink III Device Tools > Configuration > I/O > Inputs > Frequency Input > Scaling Method
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel D > Frequency Input > F1 Scaling
Frequency input scaling defines the relationship between Frequency Input Source and the pulse of the
Frequency Input. You must scale the Frequency Input so that the transmitter can interpret the data provided
by the external device.
Procedure
1. Set Frequency Input Scaling Method.
Option
Description
Frequency=Flow (default) Flow rate calculated from frequency
Pulses/Unit A user-specified number of pulses represents one flow unit
Units/Pulse A pulse represents a user-specified number of flow units
