4.2 Aligning the laser
Take precautions to prevent anyone from looking
directly into the laser beam.
Wear appropriate eye protection.
In normal use, the initial factory setup can be relied on, but if the
unit is dropped or exposed to extreme temperatures, the laser may
be realigned.
Correct alignment of the laser means the beam is emitted precisely
on a central axis in relation to the case of the sender unit in both,
the horizontal and vertical orientations.
Note: It is recommended that you label the sender unit with
the date and name of the person conducting the work so a
record of the laser alignment is maintained.
Small errors in alignment will multiply the further the laser is
projected. It is therefore important to check the laser alignment
from time to time and adjust it where necessary.
This procedure should be carried out at base in a workshop,
not on site.
It is essential for the sender unit to be accurately in position during
the alignment procedure, both vertically and horizontally. To
achieve this, place the Flying frame on a solid, stable and flat
surface with a known level surface as described in the previous
Chapter 4.1 "Resetting the angle (zeroing)"
on page 13).
1. Connect the sender unit to the meter unit so the laser can be
operated.
2. You also require a vertical surface to project the laser onto,
positioned at a distance of 10 m (33 ft) from the sender unit.
Alignment Procedure
Tools required: Torx wrench #T10
1. Switch on the laser and check where the laser dot falls on the
vertical target surface.
2. Adjust the alignment of the laser using the three M3 machine
screws around the circumference of the laser bezel.
↳The adjustment is quite sensitive, so make small adjustments
to each in turn and make sure that any of the screws are
not tightened completely.
The required accuracy is
±
5 mm (
±
0.2" hor./vert.) which
leads to a maximum deviation of 10 cm/100 m
(3.94"/328 ft).
3. Adjust the screws until the laser dot aligns precisely.
4. Switch the laser off and disconnect the sender unit.
