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.
Do this by turning the unit on, thus releasing the transport restraint (cross
laser on). Please use 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.

of point A1.

between points A2 and A3 is the tolerance.
