DeFelsko PosiTector PC Guía Rápida página 7

Before first use on a new powder and periodically thereafter, the
user should perform an accuracy check. This ensures the gage
measures properly by comparing predicted thickness values with
actual cured thickness values.

2
Zero the probe (pg 6).
3
Spray powder onto a flat, smooth metal sample.
4
Measure the uncured powder with the PosiTector PC.
5
Cure the powder.
Measure cured thickness with a magnetic or eddy current
6
coating thickness gage such as the PosiTector 6000.
Compare results.
A successful verification requires that the average of a series
of measurements by both instruments be within their combined
tolerances. If not, adjust the PosiTector PC using one of the
methods described on page 7.
For best accuracy, perform a Zero at the beginning of every shift
to compensate for temperature and humidity changes. It is also
required after a Reset (pg 9).
Place the measuring end of the PC probe into the
Powder Probe Fixture.
Select Zero from the Gage menu.
NOTE:
The Zero process can take up to 30 seconds.
Factory Calibration Symbol
Factory Calibration Symbol
This symbol indicates the instrument is measuring with factory
calibration settings. It appears whenever a Reset (pg 9) is
performed or whenever a new calibration setting (pg 9) is created.
It disappears whenever a calibration adjustment is made (pg 8)
or when a user calibration is loaded from cal memory (pg 9).
A probe Zero (pg 6) does not change the status of the symbol.
