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
the opposite end of the wall and approximately parallel to the
adjacent wall.
3. Mark the centre of the beam at two locations (C, D) at least
9 m (30') apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser back
toward the fi rst end of the wall and approximately parallel to
the adjacent wall.
6. Adjust the height of the laser so that the centre of the beam is
aligned with the nearest mark (D).
7. Mark the centre of the beam (E) directly above or below the
farthest mark (C).
8. Measure the distance between these two marks (C, E). If the
measurement is greater than the values shown in Table 2, the
laser must be serviced at an authorised service centre.
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 fl oor
positioning the laser and another person near a ceiling to mark the
position of the beam. It is important to conduct a calibration check
