Acquisition control

7.5
With the CEREC camera you can switch between two acquisition
modes:
● manual
● automatic
After being switched on, the CEREC camera is set to automatic
acquisition control.
NOTE
Image brightness
The image brightness during the scan is controlled automatically, so
that there is always optimum image brightness, largely independent of
the distance between the CEREC camera and the tooth.
The surroundings of the tooth to be scanned should be as weakly
illuminated as possible. Avoid any type of external light. Switch off the
dental light.
Changing from automatic to manual acquisition control

Automatic acquisition control
To help avoid blurred acquisitions caused by withdrawing the CEREC
camera too early, an acoustic signal sounds as soon as the acquisition
is completed. Make sure that neither the Windows volume control is at
the lowest position nor "Sound off" is activated.
1. Position the CEREC camera above the powdered preparation as
described.
2. Once a sharp acquisition is possible, images are generated and
transmitted to the 3D preview automatically.
Observe undercuts on all lateral edge lines of the preparation.
3. Move the camera until all required images have been acquired.
Ä The model is restored automatically in the 3D preview during
the acquisition.
