Postrequisites
The current pressure value is displayed in the External Pressure field. Verify that the value is
correct.
Need help? If the value is not correct:
• Ensure that the external device and the meter are using the same measurement unit.
• For polling:
- Verify the wiring between the meter and the external device.
- Verify the HART tag of the external device.
• For digital communications:
- Verify that the host has access to the required data.
- Verify that the host is writing to the correct register in memory, using the correct data
type.
• If necessary, apply an offset.

Pressure data is required for several different measurements. The meter does not measure
pressure. There are several different methods to obtain pressure data.
Prerequisites
You must be using gauge pressure.
Procedure
1. Choose Configure > Manual Setup > Measurements > External Inputs > Pressure.
2. Set Pressure Input to Enable.
3. Set Pressure Unit to the unit used by the external pressure device.
Restriction
If the API referral application is enabled, the API table selection automatically sets the
pressure measurement unit. Configure the API referral application first, then change the
pressure measurement unit if necessary.
4. Set up the pressure input.
a. Choose Configure > Manual Setup > Inputs/Outputs > External Device Polling.
b. Choose an unused polling slot.
