12 FastSCAN
Scanning position (trigger pulled in completely):
displays laser profiles and surface data on the screen in real-time and stores them
in memory
illuminates both the Laser and Scan LEDs.
Note: If the scanning equipment is set up incorrectly the Laser and Scan lights may
flash alternately when the trigger is depressed into either position.
3.2.2 Wand Sensitivity
The Sensitivity Control allows you to compensate for different subject
surface types, colors and lighting conditions. Position 1 is the least sen-
sitive and position 6 the most sensitive. For most subjects 2-3 is a good
sensitivity setting.
Setting and/or adjusting the sensitivity when scanning any new object
can be done using the Up/Down buttons on the wand, and the com-
puter. This is best done in Camera View mode:
1. Click on the Camera icon, or select View/Camera View.
2. Set the sensitivity control to position 1.
3. Pull the trigger to the Preview position.
4. Push the sensitivity control Up arrow to increase the sensitivity.
For the Cobra
TM
the red curve of the laser profile should become visible.
For the Scorpion
TM
red and green curves should become visible; the red
curve is the laser profile as viewed by the bottom camera, and the green
curve is the laser profile as viewed by the top camera.
5. If no laser profile ever becomes visible, try moving the Wand towards or away
from the object.
6. Set the sensitivity control to the lowest value that gives a clean unbroken curve(s).
7. Return to the standard view by deselecting Camera View mode.
On powering down the system, the Wand will remember the sensitivity control’s last
setting.
Note:
A too low sensitivity setting will cause only a small amount of (or no) data to be
collected.
A too high sensitivity setting may result in unwanted data or noise being collected
due to reflections or extraneous light.
