CHECKING ACCURACY – HORIZONTAL BEAM, PITCH DIRECTION (FIG. 6)
Checking the horizontal pitch calibration of the laser requires a
single wall at least 9 m (30') long. It is important to conduct a
calibration check using a distance no shorter than the distance of the
applications for which the tool will be used.
TABLE 2
1. Attach the laser to one end of a wall using its pivot bracket.
2. Turn on the laser's horizontal beam and pivot the laser toward
3. Mark the centre of the beam at two locations (C, D) at least 9 m
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser back
6. Adjust the height of the laser so that the centre of the beam is
7. Mark the centre of the beam (E) directly above or below the
8. Measure the distance between these two marks (C, E). If the
CHECKING ACCURACY – VERTICAL BEAMS (FIG. 7A, 7B)
Checking the vertical (plumb) calibration of the laser can be most
accurately done when there is a substantial amount of vertical height
available, ideally 9 m (30'), with one person on the floor positioning
the laser and another person near a ceiling to mark the position
