Calibrating the scanner
The measurement procedure used by the system requires the use of a
calibrated scanner. The CEREC Primescan / Primescan / CEREC
Omnicam / Omnicam scanner is calibrated ex works. Calibrate the
scanner after every reinstallation and after each time that it is
transported. The calibration set supplied is available for the calibration
process.
CEREC Omnicam / Omnicam: In order to achieve optimum results, the
scanner must be allowed to warm up for 15-20 minutes before
calibration.
CEREC Primescan / Primescan: In order to achieve optimum results,
the scanner must be allowed to warm up for 2 minutes before
calibration.
Recalibrate the scanner in the following cases:
● following transport (shaking stress) or during first commissioning,
● after storage in unheated or un-air-conditioned rooms (temperature
differences exceeding 30°C / 85°F),
● with temperature differences of over 15°C / 60°F between the last
calibration and operation.
● In general, carrying out a calibration is the correct process in the
event of errors in the acquisition process (such as poor image
quality or the lack of a 3D preview). In many cases, the errors can
be corrected in doing so.
● As the system may be exposed to vibration loads without knowledge
of this, it should be calibrated once a month.
