Configuration and Use Manual
MMI-20025166
Method Description
mA Input An external device sends
pressure data to the meter via
the mA Input.
Digital A host writes pressure data to
communications the meter at appropriate
intervals.
Postrequisites
Choose Menu > Service Tools > Service Data > View Process Variables and verify the external pressure value.

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.
— Verify that the host is writing to the correct register in memory, using the correct data type.
