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 cross 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.
