CALIBRATION CHECK
It’s possible for you to check the calibration of the laser. Calibration by yourself is only
approximate and the accuracy of the calibration will depend on the care with which
you proceed.
TO CHECK THE LEVEL
Checking the horizontal pitch calibration of the laser requires 2 walls, which must be at least
5 metres apart. The best calibration results can be achieved if the laser is mounted on a tripod.
1. Mark point A1 on the wall.
2. Turn the device 180 ° and mark A2 on the opposite side of A1. You now have a horizontal
reference between point A1 and A2.
3. Position the device as near as possible to the wall at the same height of point A1.
4. Turn the device 180° and mark point A3. The difference between point A2 and A3 is the
tolerance.

If the distance between A2 and A3 is more than 2mm/10m, the device is in need of calibration.
