a) Choose Service Tools > Maintenance > Routine Maintenance > SMV > Manual Verification.
b) Choose Upload Results Data from Device.
The Field Communicator stores only the most recent test result. To view earlier results, you must
upload them from the device. They will be available only for the current session.
c) Choose Show Results Table.
The Field Communicator displays detailed results for the first test.
d) Press OK to move through all test records in the local database.

Understanding SMV results

When the SMV test is completed, the result is reported as Pass, Fail, or Abort. (Some tools report the Fail
result as Advisory instead.)
Pass Smart Meter Verification does a statistical check between the factory baseline value, field reference
point, and the current Smart Meter Verification result. Pass indicates that the two values are
statistically the same.
Fail The current SMV value is statistically different than the factory baseline value.
• If the meter passes the second test, the first result can be ignored.
• If the meter fails the second test, the flow tubes may be damaged or coated. Use your process
knowledge to determine the possibilities for damage and the appropriate actions for each. These
actions might include removing the meter from service and physically inspecting the tubes. At
minimum, you should perform a flow validation and a density calibration.
Abort A problem occurred with the meter verification test (such as process instability) or you stopped the
test manually. See
actions you can take in response.
