button 8, the reference level can be changed (see
"Selecting the Reference point", page 10).
Upon selection of the measuring mode and the
reference point, all further steps are carried out by
pushing the measuring button 7.
With the reference point selected, place the
rangefinder against the desired measuring line
(e.g. a wall).
Push the measuring button 7 to switch on the
laser beam.
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.
Aim the laser beam at the target surface. Push
the measuring button 7 again to initiate the
measurement.
When the laser beam is switched on permane-
ntly, the measurement already starts after the
first actuation of the measuring button 7. In
continuous measurement mode, the measure-
ment starts immediately upon switching on.
The measured value appears after 0.5 to 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 automatic-
ally upon completion of the measurement.
When no measurement has taken place approx.
20 seconds after sighting, the laser beam is
switched off automatically to save the batteries.
Selecting the Reference Point (see figures A–E)
For measuring, it is possible to select from four
different reference points:
• The rear edge of the rangefinder or the front
edge of the laterally folded-out extension pin 18
(e.g. when measuring onward from outer
corners),
• The tip of the folded-out extension pin 18 (e.g.
when measuring from a corner),
• The front rangefinder edge (e.g. when
measuring onward from a table edge),
• The center of the 1/4" threaded hole 21 (e.g. for
measuring with the tripod).
To select the reference point, press button 8
repeatedly until the required reference point is
indicated on the display. Each time after switching
on the rangefinder, the rear edge of the
rangefinder is preset as the reference point.
Subsequent changing of the reference point for
measurements that have already been carried out
(e.g. when indicating measuring values in the
measured-value list) is not possible.
Continuous Laser Beam
If required, the rangefinder can also be switched
to the continuous laser beam mode. For this,
push the button for continuous laser beam 2.
"LASER" lights up continuously in the display.
Do not point the laser beam at
WARNING
persons or animals and do not
look into the laser beam yourself, not even
from a large distance.
In this setting, the laser beam also remains
switched on between measurements; to take
measurement, it is only required to push the
measuring button 7 once.
To switch off the continuous laser beam, briefly
push button 2 again or switch the rangefinder off.
Switching off the continuous laser beam during a
measurement automatically ends the
measurement.
Display Illumination
The display illumination is switched on and off by
pressing button 11. When no button is pressed 10
sec. after switching on the display illumination, it
is switched off to save the batteries.
The selected audio-signal adjustment is retained
when switching the rangefinder off and on.
Changing the Unit of Measure
The unit of measure can be changed at any time,
for display of the measured values, even for
already measured or calculated values.
The following units of measure are possible:
– Length measurement: m, cm, mm, ft, ft-in, in
1/32, yd,
– Area/surface measurement: m
– Volume measurement: m
button 12.
The unit of measure setting is retained when
switching the rangefinder on or off.
