Calibration, Verification and Adjustment
Three steps ensure best accuracy...
1.Calibration - typically done by the manufacturer or a
qualified lab. All probes include a Certificate of Calibration.
2.Verification of Accuracy - as done by the user on known
reference standards such as the included plastic shims, test
block or optional coating thickness standards.
3.Adjustment - to a known thickness.
Calibration
Calibration is the controlled and documented process of
measuring traceable calibration standards and verifying that the
results are within the stated accuracy of the Gage. Calibrations
are typically performed by the Gage manufacturer or by a
certified calibration laboratory in a controlled environment using
a documented process.
Verification
Verification is an accuracy check performed by the user using
known reference standards. A successful verification requires the
Gage to read within the combined accuracy of the Gage and the
reference standards.
Adjustment
Adjustment, or Calibration Adjustment is the act of aligning the
Gage's thickness readings to match that of a known reference
sample in order to improve accuracy of a gage on a specific
coating. See hickness pg. 6
