ACCURACY CONTROL
Monitor horizontal levelling
1. Choose a room ±10 m long
2. Place the instrument next to wall no. 1.
3. Switch on the instrument and let it self-level.
4. Mark the horizontal line on wall no 1.
5. Mark the horizontal line on wall no 2.
6. Move the instrument as close as possible to wall no. 2.
7. Adjust the height of the laser so that the middle of the laser cross is on the wall
no. 2 marker.
8. Then turn the instrument through 180° and note the difference between the
middle of the laser cross and the marker on wall no. 1.
9. This difference should not exceed the tolerances (See technical specs)
10. NB: The tolerance depends on the distance of the walls between which the
inspection has been carried out. This distance should be multiplied by 2.
Hence, if the instrument has an accuracy of 1 mm / 10 m, then in our example the
calculation is: 10 m distance x 1 = 10 m. Tolerance is 2 mm / 20 m.
