Performing the Zero CAL-CHECK™ Calibration Validation Test
The Zero CAL-CHECK™ test is a companion test to CAL-V™. Unlike
CAL-V™, which may be performed in the pipe and at process conditions,
Zero CAL-CHECK™ must be performed at zero flow to ensure a valid
test result. This test is used to confirm that the flow meter still retains
its original NIST-traceable calibration at zero flow and that the sensor is
free of film or residue tat may affect readings. The test takes less than 5
minutes to complete. At the conclusion of the test, a Pass or Fail message
will be displayed. Press
F4
at the conclusion of the test to return to normal
measuring mode or to terminate the test.
