Instructions for use KEY Laser III 1243
4 Operation

4.17 Detector calibration

KaVo recommends checking the detection function each time before the Key Laser

1243 is used in detection or feedback mode. The hand-piece is held against the

reference. If the values on the reference do not correspond with the values on the

touchscreen, take the following steps.

When the detector calibration key in the start menu is pressed, the detector calib‐

ration menu opens.

With the aid of this menu, the detection of the laser is calibrated. The results of the

calibration are administered separately for each handpiece (and each fibre tip).

4.17.1 Check or change reference value

Note

The value indicated on the reference must correspond to the reference value on

the touchscreen.
