LASER CLASSIFICATION

General
The following directions (in accordance with the state of the art -
international standard IEC 60825-1(2007-03) and IEC TR 60825-14
(2004-02)) provide instruction and training information to the
person responsible for the device and the person who actually
uses the equipment, to anticipate
and avoid operational hazards. The person responsible for the
device must ensure that all users understand these directions and
adhere to them.
Devices classified as laser class 1, class 2 and class 3R do not
require
laser safety officer involvement,
protective clothes and eyewear,
special warning signs in the laser working area if used and operat-
ed as defined in this user manual due to the low eye hazard level.
Devices classified as laser class 2 or class 3R may cause dazzle,
flash blindness and afterimages, particularly under low ambient
light conditions.

ACCURACY CONTROL

Monitor horizontal levelling
1. Choose a room ±10 m long
2. Place the instrument next to wall no. 1.
3. Switch on the instrument and let it start levelling.
4. Mark the horizontal line in the middle of the cross on wall
no 1.
5. Turn the instrument through 180° and mark the laser beam in
the middle of the cross on wall no. 2.
6. Move the instrument as close as possible to wall no. 2.
7. Adjust the height of the laser so that the middle of the laser
cross is on the wall no. 2 marker.
8. Then turn the instrument through 180° and note the differ-
ence between the middle of the laser cross and the marker
on wall no. 1.
9. This difference should not exceed 2 mm.
10. NB: The tolerance depends on the distance of the walls
between which the inspection has been carried out. This dis-
tance should be multiplied by 2. Hence, if the instrument has
