6. Pivot the tool through 90°.
The lower intersection must remain on the center of the cross.
7. Mark the top point of intersection of the laser lines on the ceiling.
8. Repeat the procedure after pivoting the tool through 180° and 270°.
Form a circle on the ceiling from the 4 marked points. Measure the diameter of the circle D in
millimeters or inches and the height of the room in meters or feet.
9. Calculate the value R.
▶
The value R should be less than 3 mm (corre-
sponds to 3 mm at 10 m).
▶
The value R should be less than 1/8".
5.10.2 Checking the leveling of the laser beam
1. The distance between the walls must be at least 10 m.
2. Place the tool on an even, level surface approx. 20 cm from the wall (A) with the point of intersection of
the laser lines directed toward the wall (A).
3. Mark the point of intersection of the laser lines with a cross (1) on wall (A) and with a cross (2) on wall (B).
4. Place the tool on an even, level surface approx. 20 cm from wall (B) and carefully aim the point of
intersection of the laser lines at cross (1) on wall (A).
5. Use the adjustable feet to adjust the height of the point of intersection of the laser lines so that the point
of intersection coincides exactly with the mark (2) on the wall (B). In doing so, make sure that the bubble
level remains centered.
6. Mark the point of intersection of the laser lines again with a cross (3) on the wall (A).
7. Measure the offset D between the crosses (1) and (3) on the wall (A) (RL = room length).
