Factory Calibration Symbol
Factory Calibration Symbol
This symbol indicates the instrument is measuring with factory
calibration settings. It appears whenever a
Reset
(pg 12) is
performed or whenever a new calibration setting (pg 11) is created.
It disappears whenever a calibration adjustment is made (pg 10) or
when a user calibration is loaded from cal memory
(pg 11). A probe
Zero
(pg 8) does not change the status of the
symbol.
Place the measuring end of the
PC
probe into the
Powder Probe Fixture.
Select
Zero
from the Gage menu.
The Zero process can take up to 30 seconds.

Verification of Accuracy
Verification of Accuracy
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.

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 9.
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 12).
