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.

height of point A1.
