Calibration and Optimization

Æ Optimize Æ Measure
The 6000 is factory aligned and performs
an automatic self-check each time it takes
a measurement. For many applications
no adjustment is necessary - just ZERO
on the uncoated substrate, then measure.
However, gage readings can be
influenced by changes in substrate
shape, diameter, composition, surface
roughness or by measuring in a different
location on the part.
The 6000 can be Calibrated to verify that
it is operating correctly and measuring
accurately. The 6000 can also be
Optimized for use on your specific
application.
Calibration is the act of measuring
known Calibration Standards, and
verifying that the results are within the
tolerance of the Gage.
Optimization is the act of changing the
Gage’s thickness reading 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.
The need to Calibrate or Optimize
depends upon a number of factors
including the level of accuracy required
and the need to satisfy ISO or other in-
house quality control requirements.
