7. Operation
7.2.2 Display illumination
= Illumination key
The illumination key, switches the display
illumination On or Off. In the dark or in
very bright light, e.g. sunlight or a strong
spotlight the display illumination helps the
user to read the display more easily.
- NOTE-
Display illumination consumes additional
power. If it is used frequently, a shorter
battery life must be expected.
7.3 Optical sight
The built-in optical sight is a great benefit
when measuring outside and whenever the
laser spot is poorly visible. Thanks to the
optical sight, even at long distances can be
easily and precisely aimed at. Whenever
the rangemeter’s laser is On, the laser spot
can be seen in the optical sight. If the laser
spot is not visible in the optical sight,
either the measurement is completed or
the laser beam has switched off, the timer
of 60 seconds may have expired.
The optical sight runs parallel to the laser
beam.
Typical measuring procedure with the
optical sight
– Press the "Measure" key to activate
the laser beam.
– Aim for the target with the laser spot in
the optical sight.
– Press the "Measure" key or "Side
measure" key keep aiming until the laser
spot in the optical sight disappears.
– Read the distance in the display.

- NOTE -
It is practical for the optical sight to be
used for distance above 10 m (30ft).
7.4 Measuring distances
Distance measurements can be taken to all
“non-cooperating” stationary targets, i.e.
concrete, rock, wood, plastic, paper, etc.,
The use of prisms or other strongly
reflecting targets is not permitted and, if
used, might falsify the results.
7.4.1 Measuring references
= switch key
The range meter can measure distances
from three different measuring reference
points.
By pressing the "switch" key on the left at
the front of the range meter the measuring
reference point toggles between front edge
and rear edge. If the spike is folded out
90°, the reference position is set to the
end of the spike.
The reference for the measuring extension
PDA 70 is activated when the range meter
is switched off. While the reference key
(upper left) is pressed and the range meter
switched On with the On / Off key (upper
right) the spike symbol starts blinking in
the display. The reference for the measur-
ing extension is deactivated when the
range meter is switched Off.
