1. In a high room (for example in a stairwell with a height of 10 m), make a mark (a cross) on the floor.
2. Set the laser on a flat, horizontal surface.
3. Switch the laser on and unlock the pendulum.
4. Position the laser so that the lower plumb beam coincides with the center of the cross marked on the
floor.
5. Mark the upper plumb point on the ceiling.
6. Turn the laser through 90°.
The lower plumb beam must remain on the center of the cross.
7. Mark the upper plumb point on the ceiling.
8. Repeat the procedure after pivoting the tool through 180° and 270°.
9. Form a circle on the ceiling from the 4 marked points. Measure the diameter of the circle D in millimeters
or inches and the room height RH in meters or feet.
10. Calculate the value R.
▶ The value R should be less than 3 mm (1⁄8).
▶ If the result is out of tolerance, consult Hilti
Service.
