The test takes approximately four minutes to complete. During the test:

•

The indicator at the bottom of the panel turns yellow and the monitor bar shows the progress of 
the meter verification procedure.

•

If a problem occurs during the test, the test will be aborted. The indicator will turn red and a 
popup window will indicate why the test could not be completed. Correct the problem before 
restarting the test.

•

If you need to stop the procedure before the end of the test, click 

. 

The test will stop immediately, and all the data collected for this test will be discarded.

At the end of the test, a dialog box describing the result of the test will appear:

•

Meter passed verification—The test result is within the range defined by the current 
Specification Uncertainty Limit parameter. If transmitter zero and configuration match factory 
values, the sensor will meet factory specifications for flow and density measurement. It is 
expected that the meter will pass meter verification every time the test is run. Click 

 to close 

the popup window, then click 

 to go to the next panel.

•

Meter failed verification—The test result is not within the range defined by the current 
Specification Uncertainty Limit parameter.

-

Micro Motion recommends that you immediately re-run the meter verification test. To do 
so, click 

 to close the dialog box and automatically start a new test. If the meter passes 

the second test, the first Fail result can be ignored. If the meter fails the second test, the 
flow tubes may be damaged. Use the knowledge of your process to consider the type of 
damage and determine the appropriate action. 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. For more information on these procedures, 
refer to the transmitter manual.

-

If you don’t want to re-run the test, click 

 to close the dialog box, then click 

 to go 

to the next panel.

The 

 displays the total number of meter verification tests that have been 

performed on this transmitter.

•

The counter is incremented each time a meter verification test is completed, whether the test 
passed of failed.

•

The counter will not be incremented if the test is aborted, either automatically or by the user.

To ensure the safety of your process:

•

Disable all control loops for the duration of the procedure.

•

Ensure that any data reported during this period is handled appropriately.
