LASER CLASSIFICATION

General
The following directions (in accord-
ance with the state of the art - interna-
tional standard IEC 60825-1(2007-03)
and IEC TR 60825-14 (2004-02)) pro-
vide instruction and training informa-
tion to the person responsible for the
product and the person who actual-
ly uses the equipment, to anticipate
and avoid operational hazards. The per-
son responsible for the product must
ensure that all users understand these
directions and adhere to them.
Products classified as laser class 1, class
2 and class 3R do not require:
∙ laser safety officer involvement,
∙ protective clothes and eyewear,
8
∙ special warning signs in the laser
working area
if used and operated as defined in this user
manual due to the low eye hazard level.
Products classified as laser class 2 or
class 3R may cause dazzle, flash blind-
ness and afterimages, particularly under
low ambient light conditions.

ACCURACY CONTROL

Monitor horizontal levelling
∙ Choose a room ±10 m long
∙ Place the instrument next to wall no. 1.
∙ Switch on the instrument and let it
self-level.
∙ Mark the horizontal line on wall no 1.
∙ Mark the horizontal line on wall no 2.
∙ Move the instrument as close as possi-
ble to wall no. 2.
∙ Adjust the height of the laser so that the
middle of the laser cross is on the wall
no. 2 marker.
∙ Then turn the instrument through 180°
and note the difference between the
middle of the laser cross and the mark-
er on wall no. 1.
∙ This difference should not exceed the
tolerances (See technical specs)
IMPORTANT:
∙ The tolerance depends on the dis-
tance of the walls between which the
inspection has been carried out. This
distance should be multiplied by 2.
Hence, if the instrument has an accura-
cy of 1 mm / 10 m, then in our example
the calculation is: 10 m distance x 1 =
10 m. Tolerance is 2 mm / 20 m.
∙ After checking the X-axis repeat the
same steps for the Y-axis.
