B.2.1
Scan Start
This function adjusts the position of the CCD camera and the lamps relative to each other.
The electronic gear mentioned previously is fine-tuned with this routine. The first test
performed is the maximum turn of the lamps. The lamps will hit against their mechanical
end position, which will produce an audible sound. This is necessary to check whether the
lamps can be turned in and out far enough.
Then the scanner scans the test target, finds the white to black change in the middle of
the test target and takes this position as the optical middle. It is very important to move the
test target against the neck and center it as precisely as possible. Any deviation of the test
target in the horizontal direction from the ideal position will be present in all scans
afterwards.
After the optical middle is established, the scanner moves its CCD camera to the newly
found middle position. Both lamps are moved backward and forward to find the maximum
brightness of the beam. When the position is found it is stored. This will override the
previous manual setting. The manual setting was necessary to have at least some
synchronized lights during the first step when the scanner tries to locate the optical
middle.
To perform the function follow the steps 1) and 2) as described on the screen.
