Measuring Procedure
The rangefinder offers a variety
of different measuring modes that
can be selected by pushing the
corresponding mode button (see
"Measuring Mode"). After
switching on, the rangefinder is in
the "length measurement mode".
Also, it is possible to select any of
the four different reference points
for the measurement by pushing
the reference point button 1 (see
"Selecting the Reference Point").
After switching on, the rear edge
of the rangefinder is preset as the
reference point.
Upon selection of the measuring
mode and the reference point, all
further steps are carried out by
pushing the measuring
button 10.
With the reference level selected,
place the rangefinder against 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.. 20 seconds
after sighting, the laser beam is
switched off automatically to save
the batteries.
Selecting the Reference Point
(see figures B–E)
For measuring, it is possible to
select from four different
reference points:
• the rear edge of the
rangefinder (e.g., when placing
the measuring rangefinder
flush against a wall),
• the rear edge of the extension
pin 15 (e.g., for measurements
out of corners).
• the front edge of the
rangefinder (e.g., as when
measuring from the edge of a
table onward),
• the center of the 1/4" threaded
hole 17 (e.g., for measuring
with the tripod).
