– To switch on the laser beam, lightly press the measurement button 7
in the middle or press at the side.
– Aim at the target.
■Do not point the laser beam at persons or animals.
– To measure, press the measure button 7completely down.
The measured value appears after 0.5 to 4 s. The end of the measure-
ment is indicated by an acoustical signal. The duration of the measure-
ment is dependent on the distance, light conditions and reflection charac-
teristics of the measured surface. After completion of the measuring
procedure, the laser switches off automatically.
Continuous Pointer Mode
As required, the unit can be switched to continuous laser beam (continu-
ous pointer mode). For this purpose, press the continuous pointer mode
button 10. In this mode, the laser beam also remains switched on be-
tween measurements. For measuring, only a single pressing down com-
pletely of the measurement button 7is necessary.
■Do not look into the laser beam.
■Do not point the laser beam at persons or animals.
To switch off the continuous laser beam, press the continuous pointer
mode button 10 or switch off the unit. After renewed switching on, the
unit is again in the normal mode (the laser beam is switched on only when
the measurement button 7is pressed).
The instrument measures from the back end of the instrument.
– The receiving lens and the outlet of the laser beam should not be cov-
ered during a measurement.
– Do not move the instrument during a measurement (Exception: Con-
tinuous measurement function including minimum/maximum meas-
urement). If possible, rest the instrument on or against the measuring
point.
– The measurement takes place at the middle point of the light spot,
also for obliquely illuminated target surfaces.
– The measuring range depends on the light conditions and the reflec-
tion characteristics of the measured surface. For working outdoor and
with strong sunlight, use the laser viewing glasses 28 (accessory) for
better visibility of the laser point or shade the target surface.
– When measuring to transparent surfaces (e.g. glass, water) or reflect-
ing surfaces, erroneous measurement can result. Porous or struc-
tured surfaces, air strata with different temperatures or indirectly re-
ceived reflections can also influence the measured value. These
effects are caused by physical properties and can therefore not be ex-
cluded by the measuring instrument.
– In the dark, press the display lighting button 9. The display is then
lit. To switch off the lighting, press the button 9again.
– By means of the upper and side aligning aids 4, aiming over longer
distances is facilitated. For this purpose, sight along the upper or side
aligning aids. The laser beam runs parallel to these lines of sight
(see Fig. ).
– When the unit is switched off, all values stored in memory are re-
tained. However, when the end piece is removed (changing of the
end piece or the batteries), the memory contents are lost.
