BTI MLL 360 Mode D'emploi page 10

Checking horizontal line:
1. Position the laser on a tripod or on a horizontal surface at approx. 15 cm distance from
wall A and approx. 10 m from wall B.
2. Turn on the device and allow te MLL 360° to level.
3. Mark laser position on wall A.
4. Turn the divice by 180° and mark laser position on wall B.
5. Reposition the laser at approx. 15 cm distance from wall B.
6. Adjust the laser position (height) to align laser beam with marking on wall B.
7. Turn the divice by 180° and mark laser position on wall A.
8. If both markings on wall A are aligned, the laser is calibrated perfectly.
9. In case the markings are not aligned, measure the distance in between. Divide the value
by 2. The result displays the laser accuracy related to the distance between the two
walls. It should not exceed 2 mm on 10 m, otherwise the laser has to be calibrated.
