If you chose to poll for pressure data:
a. Select the Polling Slot to use.
b. Set Polling Control to Poll as Primary or Poll as Secondary, and click Apply.
Tip
• Poll as Primary: No other HART masters will be on the network.
• Poll as Secondary: Other HART masters will be on the network. The Field Communicator
is not a HART master.
c. Set External Device Tag to the HART tag of the external pressure device, and click
Apply.
d. Ensure that the primary mA Output is wired to support HART communications
with the external pressure device.
If you chose to use a fixed pressure value:
a. Set Fixed Value to the value to use, and click Apply
If you want to use digital communications, click Apply, then perform the necessary
host programming and communications setup to write pressure data to the
transmitter at appropriate intervals.

Set Pressure Compensation to Enabled.
Enter Flow Cal Pressure for your sensor.
The calibration pressure is the pressure at which your sensor was calibrated, and
defines the pressure at which there is no pressure effect. If the data is unavailable,
enter 20 PSI.
Enter Flow Press Factor for your sensor.
Description
The transmitter will use the pressure value that it reads from
memory.
• Fixed Value: The configured value is used.
• Digital Communications: A host writes transmitter data
to transmitter memory.
