Preparing the calibration check
It is possible for you to check the calibration of the laser. To do this, position
the device midway between 2 walls, which must be at least 5 metres apart.
Switch the device on (Laser line on). The best calibration results are
achieved if the device is mounted on a tripod.
1. Mark point A1 on the wall.
2. Turn the device through 180° and mark point A2. You now
have a horizontal reference between points A1 and A2.

3. Position the device as near as possible to the wall
at the height of point A1.
4. Turn the device through 180° and mark point A3. The
difference between points A2 and A3 is the tolerance.
