4. OPERATING
INSTRUCTIONS
This laser was designed to measure
distances indoors.
To ensure a safe operation, it is
necessary to consider the following
aspects:
� Before using, check if every fixing
screw is properly tightened. It is
important to check regularly the laser
to ensure every safety issues and
performance;
� Prevent the device from bumping
or falling. Laser damage can impair
accuracy;
� The reception lens and the laser
ray outlet must not be covered or
obstructed while measuring;
� Keep the laser ray outlet and the
reception lens always clean;
� In case of a strong presence of light,
and to obtain a better visibility of the
laser ray, use laser glasses, a target
plate for the laser beam or shade the
target surface ;
4.1 - TURN THE DEVICE ON/
OFF
1. To turn the device on, press “Power
ON/Measurement” button (2) until the
display (1) shows some data;
2. To turn the device off, press the

4.2 - MEASURING PROCEDURE
(FIG. C)
The back edge of the device is always
the measurement reference level.
1. Lean the device back edge (10)
against the desired measurement
starting point (for ex., a wall);
2. Press the “Power ON/Measurement”
(2) button to turn the laser on;
3. To start measuring, press again
“Power ON/Measurement” button;
4. Point the laser ray (8) towards the
surface to be measured;
5. To start a new measurement, press
again “Power ON/Measurement”
button.
The duration and quality of the
measurements depend on the distance,
the light conditions and the reflective
properties of the target surfaces.
There are surfaces that may cause
measuring errors:
� Clear surfaces (glass, water);
� Reflective surfaces (polished metal,
glass);
� Porous surfaces (insulating material);
� Surfaces with structures (rough
plaster, natural stone);
� Inclined surfaces;
On these cases, a target plate shall be
used over the surfaces.
4.3 -CONTINUOUS
MEASUREMENT
To obtain distances over a fixed
surface, use the following procedure:
1. Press and hold the “Power ON/
Measurement” button (2);
2. Point the laser ray (8) towards the
surface and move the device towards
the distance to be measured. The
measurement is updated every 0.5
seconds;
3. Press the “Power ON/
Measurement” button” or “Power OFF/
Reset” (3) button to stop continuous
measurement.
4.4 -MEASURING UNIT
SELECTION
