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 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 Thickness pg. 6
