1. Set up the laser on a tripod or on a solid surface between two walls A and B, approximately
5 meters apart.
2. Position the laser level approximately 2.5 meters from the center of the room.
3. Switch ON the self-leveling mode and press the button to project the horizontal line towards
wall A and B.

5. Move the laser level approximately 5 meters away and turn the laser 180° towards wall A
and B.
6. Mark the center of the laser line point a2 on wall A and point b2 on wall B.
7. Measure the distances:
Δa= |a2- a1|
Δb= |b1- b2|
8. The difference | Δa – Δb| should be no more than 2 mm.
