Calibration, Verification and Adjustment
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 calibration step blocks.
3.Adjustment - to a known thickness or sound velocity for the
material to be measured
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
Gage accuracy can and should be verified using known reference
standards of the material to be tested.
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. See Calibration Adjustment pg. 6.
