Calibration - Omega Scanner 3D User Manual

CALIBRATION

Changes in the environment such as temperature or pressure variations may modify
the Scanner's mechanical configuration. To ensure the quality and accuracy of the
data acquired by this high precision equipment, calibration is recommended at the
beginning of each scanning session.
Calibration is accomplished using the calibration plate that was included with the
Scanner. The calibration plate should be at a temperature close to factory calbration
conditions (20-22° C, or 68 - 72° F).
The reflective targets on the calibration plate do not have the same coating as the
targets used for scanning. As a result, the calibration targets have a greater sensitivity
to exterior contaminants. If you touch the targets on the calibration plate with your
fingers or with any other oily substance, the calibration plate will have to be
replaced.
1. The first step depends on the software you are using:
• For OMEGA, click
Scan Shape step in the Capture
Stack, then select Calibrate
Scanner.
2. When the Scanner Calibration
screen appears, click Acquire.
3. Lay the calibration plate on a
stable and level surface. Make
sure that there are no reflective
objects nearby.
• For Tracer Version 12.2, select
in the
Capture with Omega Scanner
from the Start screen, then click
Optimize Scanner.
