1. Place the line laser near the center of a room with approx. 5 m walls.
2.
Adjust the line laser so that the bubble in the level comes to the center of the red
circle.

B’
5.
Move the line laser to the position 1m away from the wall and adjust the bubble in
the level.
6. Mark B’ at the position of the horizontal laser line .
7. Turn the line laser by 180°and mark A’ at the position of the horizontal laser line.
The result is normal if the difference between A-A’ and B-B’ is within 1 mm.

8. Rotate the line laser horizontally and measure the maximum difference in the
horizontal laser line with A’.
The result is normal if the deviation at point A’ is within 1 mm.
