Calibration, Verification & Adjustment
Calibration, Verification & Adjustment
Three steps ensure best accuracy…
1. Calibration: typically done by the manufacturer or qualified lab
2. Verification of Accuracy: as done by the user
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 sample in
order to improve the effectiveness of the Gage on a specific
surface or in a specific portion of its measurement range. 1-point
or 2-point calibration adjustments are possible.
The symbol disappears whenever a calibration
adjustment is made to the Gage.
The PosiTector 6000 is factory calibrated and performs an
automatic self-check each time it takes a measurement. For
many applications, no further adjustment is necessary after a
Reset (pg.16). Just check ZERO on the uncoated substrate, then
measure.
