1 Smart Meter Verification
Smart Meter Verification (SMV) is a Micro Motion diagnostic tool that allows you to
compare the sensor’s current performance to benchmark data established at the factory.
Using the Modbus interface, you can:
• Execute an SMV test from the Modbus host
• Set up a scheduled test execution
• Read result data for the twenty test results stored on the transmitter
Note
You can view more than twenty previous test results and see detailed test reports only
if SMV is licensed.
For more information on requirements and features, see your transmitter configuration
and use manual.
