measuring tool. After severe exterior effects to the
measuring tool, it is recommended to carr y out an
accuracy check each time before continuing to work.
SWITCHING ON AND OFF
To switch on the measuring tool, press the measuring/on
button (1) for a few seconds.
When switching on the measuring tool, the laser beam is
also switched on.
To switch off the measuring tool, press the off/memory
clear button (2) for a few seconds.
If none of the buttons are pressed for approx. 3 minutes,
the measuring tool is switched off automatically in order to
extend the service life of the battery.
WARNING! Do not point the laser beam at persons or
animals and do not look into the laser beam yourself,
not even from a large distance.
SINGLE LENGTH MEASUREMENT (Fig. 1, 2)
1. Press measuring/on button to activate the laser, and aim
at the object which is to be measured.
2. Press measuring/on button again to take measurement.
The measured value is indicated at the bottom in the
display (3).
3. Press the measuring/on button again to take a second
measurement. The second length is shown in the lowest
row of the display.
The measured value typically appears after 0.4 seconds
and at the latest after 3 seconds. The duration of the
measurement depends on the distance, the light conditions
and the reflection properties of the target surface. The end
of the measurement is indicated by a signal tone. The laser
beam is switched off automatically upon completion of the
measurement.
When no measurement has taken place approx. 3 0
seconds after sighting, the laser beam is switched off
automatically to save the batteries.
CONTINUOUS/TRACKING MEASUREMENT (Fig. 3)
For continuous/tracking measurements, the measuring tool
can be moved relative to the target, whereby the measuring
value is updated approx. every 0.4 seconds. In this manner,
as an example, you can move a certain distance away from
a wall, while the actual distance can always be read. To
start continuous measurements, push measuring/on button
for a few second.
To stop continuous measurement, press off/clear button .
Pres measuring/on buttonit to exit and return to the single
length measurement mode.
HOLD FUNCTION
While continuous measurement is in process, press the
measuring/on button to hold the measurement process,
and the current measuring value is displayed on the
display, but is no longer continuously updated.
DISPLAY BACKLIT
When switching on the measuring tool, the display backlit
is also switched on. The indications on the display is clearly
visible even in dark situation.
If none of the measuring tool button are pressed for approx.
30 seconds, the backlit will be turned off automatically.
Press any button to turn it on again.
WORKING ADVICE GENERAL INFORMATION
The reception lens (7) and the laser beam outlet (6)
must not be c overed w hen t ak ing a measurement.
The measuring tool must not be moved while taking a
measure¬ment (with the exception of the continuous
measurement function). Therefore, place the measuring
tool, as far as this is possible, against or on the measuring
points. Measurement takes place at the centre of the laser
beam, even when target surfaces are sighted at an incline.
INFLUENCE EFFECTS ON THE MEASURING RANGE
The measuring range depends upon the light conditions
and the reflection properties of the target surface. For
improved visibility of the laser beam when working outdoors
and when the sunlight is intense, use the laser viewing
glasses (accessory) and the laser target plate (accessory),
or shade off the target surface.
INFLUENCE EFFECTS ON THE MEASURING RESULT
Due to physical effects, faulty measurements cannot be
excluded when measuring on different surfaces. Included
here are:
. transparent surfaces (e.g., glass, water),
. reflecting surfaces (e.g., polished metal, glass),
. porous surfaces (e.g. insulation materials),
. structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate (accessory) on these
surfaces.
Also, air layers with varying temperatures or indirectly
received reflections can affect the measured value.
