When the measuring tool is inserted in the measuring rail 26, it is always
in the angle measurement function after switching on by pressing the
measuring button 2. Other measuring modes can also be switched by
pressing the respective function/mode button (see "Measuring Functions",
page 17).
Briefly press the measuring button 2 to switch on the laser beam.
Aim the laser beam at the target surface. Briefly press the measuring
button 2 again to inhiate the measurement.
When the laser beam is switched on permanently, the measurement
starts after the first actuation of the measuring button 2. In continuous
measurement mode, the measurement starts immediately upon switching
on.
Typically, the measured value appears after 0.5 second and latest after
4 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 takes place for approx. 20 seconds after turning
on the laser, the laser beam turns off and the measuring tool automatically
switches off to save the battery after 5 minutes.
Selecting the Measurement Reference (see figure A)
After switching on, the rear edge of the measuring tool is preset as
the reference measurement for the measurement. By pressing the
measurement reference button 10, the measurement reference can be
changed (see "Measuring Functions", page 3).
Place the measuring tool with the selected measurement reference against
the desired starting point of the measurement (e.g. a wall).
For the measurement, you can select between four measurement
references:
– The rear edge of the measuring tool or the front edge of the 90°
folded-out positioning pin 9 (e.g. when measuring onward from outer
corners),
The tip of the 180° folded-out positioning pin 9 (e.g. when measuring
–
from a corner),
