Digital
communications
A host writes pressure data to
the meter at appropriate
intervals.
a. Choose Configure > Manual Setup > Measurements >
Optional Setup > External Variables > External Pressure.
b. Set Pressure Compensation to Enable.
c. Perform the necessary host programming and
communications setup to write pressure data to the
transmitter at appropriate intervals.
Postrequisites
Choose Service Tools > Variables > Processand verify the values for External Temperature and External
Pressure.

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 the mA Input:
— Verify the wiring between the meter and the external device.
— Verify the power configuration for Channel D. If external power is required, ensure that the loop is
powered.
— Verify the Lower Range Value and Upper Range Value settings for the mA Input.
— Perform an mA Input trim.
— Adjust the mA Input damping value.
• For digital communications:
— Verify that the host has access to the required data.
