.
2.
(Optional) Enter identification data.
3.
Set
Altitude
to the value that is closest to the altitude of your meter, measured from
sea level.
Valid values are 0000 to 6000 feet, and 0000 to 2000 meters.
4.
Click
Start
, then wait while the meter collects and analyzes process data.
This step should be complete in approximately 20 seconds.
5.
Check the results in the Results data display.
•
If all process variables passed the tests, no action is required. Click
Close
to exit
the wizard.
•
If one or more process variables failed the test:
-
For problems with Line Temperature, Case Temperature, or Tube-Case
Temperature Difference, verify that the ambient temperature of the meter is
stable, and that the meter temperature has stabilized in the test location.
Then retry the Known Density Verification procedure.
-
For problems with Verification Time Period Signal or Drive Gain, ensure that
the meter is clean and dry. Then retry the Known Density Verification
procedure.
-
If the Known Density Verification procedure continues to fail, contact
Micro Motion customer service.
9.1.3
Perform the Known Density Verification procedure using
the Field Communicator
The Known Density Verification procedure is used to verify that the meter's current
operation matches the factory baseline. If the meter passes the test, the meter does not
have any physical problems such as denting, bending, twisting, erosion, or corrosion.
Prerequisites
Power down the meter, remove the meter from the process, and place it in a protected
stable environment.
Ensure that the sensor tubes are clean and dry.
Minimize variation in ambient temperature.
Eliminate or minimize vibration.
Power up the meter.
