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
NOTE:
The PosiTector 200 measures most polymer coatings
accurately out-of-box with no adjustment required.
Zero
The probe must be periodically zeroed using the Zero menu option
to compensate for both temperature and probe wear effects. Before
using, allow the probe to reach ambient temperature. Wipe the
probe clean of couplant.
If measurements will be made in extreme hot or cold temperatures,
it is recommended to Zero the probe in the working environment.
If measurements will be made on rough surfaces, it is recommended
to periodically Zero the probe to compensate for wear.
Set Range
The measuring range of each probe can be changed depending
on the specific application or the expected thickness range of the
coating system.
For most applications, the default range values do not need to
be adjusted. But some conditions, like surface roughness, may
cause the Gage to display very low or non-repeatable readings.
In this case, the low range may be increased to cause the Gage
to only display readings above the Lo value set by the user.
