Calibration Validation Test
This menu allows the user to confirm the calibration accuracy of the
MTI10/MTL10 Flowmeter by verifying the functionality of the sensor
and sensor signal processing circuitry. During the CAL-V™ calibration
validation test, the microprocessor adjusts the current to the sensor
elements and determines the resulting electrical characteristics. These
site-determined characteristics are compared with the data that was
collected at the factory during the original meter calibration. Matching
data within established tolerances confirms the meter is accurate within
published accuracy specifications.
This test can be performed under no flow or normal flow conditions. The
test takes about 4 minutes to complete. At the conclusion of the test, a
Pass or Fail message will be displayed.
Note: If the CAL-V™ test is performed using the MTI10/MTL10 View™
Software, at the completion of the test, a CAL-V™ Certificate may be
printed for a record of the test. This certificate will display the CAL-V™
values and a pass/fail result.
