8.1.1 Height accuracy (fig. )
1. Place the tool on a level surface (floor).
2. Switch on the horizontal and vertical beams.
3. Set up the first target plate 20 cm in front of the
tool. The vertical laser line must just touch the left
edge of the first target plate. The height of the first
target plate must be adjusted so that the horizontal
beam strikes the plate exactly on the line printed on
it.
4. Set up the second target plate 5 meters beyond the
first plate. The vertical laser line must just touch the
right edge of the second target plate. The second
target plate must also be set up so that the
horizontal beam strikes the plate exactly on the line
printed on it.
5. Mark the position of the vertical beam on the floor
about 20 cm beyond the second target plate.
6. Move the tool to position 2 (see fig. )
and place it on the mark. Adjust the height of the
tool so that the horizontal laser line strikes the
horizontal line printed on the plate. The vertical laser
line must be projected approximately between the
target plates, as before.
