Reflections
NOTE
Measuring errors due to reflections on the measured object
Strong extraneous light leads to unwanted reflections on the measured object.
This affects the accuracy of the measurements.
•
Select a workplace away from a window or not affected by high levels of artificial lighting.
•
Cover the opening during the scanning process, e.g. with light-tight foil/dust-cover.
Vibration
NOTE
Measuring errors due to vibrations
The surface on which the scanner is placed must not vibrate. Vibration will cause inaccurate measurement results.
•
Place the scanner on a sturdy, stable base able to support at least twice the weight of the scanner, i.e. 2 x 23 kg.
•
Stabilize the base by means of a strutted under frame or by attaching it to a stable wall.
Calibration
NOTE
Inaccurate measurements due to failure to calibrate or use of a damaged calibration model
The measuring accuracy of the scanner is only guaranteed if the scanner is calibrated. This operation requires the use
of a calibration model and the associated default values.
The calibration model can be mechanically damaged. This can only be tolerated in the border area.
•
Perform the calibration of the scanner after commissioning, after transporting it and whenever the software asks
you to do so during operation.
•
Only start the procedure when the values registered in the software match the values of the calibration model.
•
Check whether the calibration model is damaged at a central location.
•
Only use the calibration model if it is in perfect condition.
Model fastening
NOTE
Damage to the scanner and the models due to missing or incorrect fastening
Due to the motion of the axes inside the scanner, unsecured or incorrectly secured models will fall down during the
scanning process.
•
Do not place any objects on top of or inside the scanner.
•
Never place unfastened models inside the scanner.
•
Only use the included object holder or approved accessories to fasten models.
•
When fastening occlusal models with rubber bands, only use stable, unused rubber bands.
Thin or porous rubber bands can tear.
•
Always fasten models on the flexible object holder and the Multi die adapter using adhesive pads made of modeling
clay.
•
Only place stump models prepared with metal pins inside the Multi die adapter.
•
However, should a model still fall down, turn off the scanner immediately.
Then remove the model or all broken pieces from the interior of the scanner.
Adhesive materials
NOTE
Damages to models due to unsuitable adhesive materials
Models, object holders and the scanner get soiled or are even damaged through the use of adhesive tape, instant
glue or similar products.
•
Only fasten models using adhesive pads made of modeling clay.
