target surface is available as a
reflector. Correct results are
achieved only when the laser
beam and the sought distance
form an exact right angle (90°)
(Pythagorean Theorem).
In the illustrated example, the
length
B is to be determined. For
this purpose, A and C must be
measured. A and B must form a
right angle.
For indirect length
measurements, push button
11
until the indicator for indirect
length measurement appears
in the display.
Measure the distance A as for a
length measurement. Pay
attention that the line segment
A
and the sought distance B form a
right angle. Afterwards,
measure the distance
C . The
laser beam remains switched on
between both measurements.
Pay attention that the reference
point of the measurement (e.g.,
the rear edge of the rangefinder)
is at the exact same location for
both measurements.
After completing the second
measurement, the distance
B is
calculated automatically.The last
individual measured value is
indicated at the bottom in the
display, while the final result
B is
indicated at the top in decimal
feet or meters.
Multi-Surface Area
Measurement (see figure I)
The multi-surface area
measurement is used to
determine the sum of several
individual surfaces with a
common length.
In the example shown, the total
surface of several walls that have
the same room height
A , but
different lengths B , are to
be determined.
For multi-surface area
measurements, push button
11
until appears in the display.
Measure the room height A as for a
length measurement. The
measured value is indicated both at
the top and bottom in the display.
The laser remains switched on.
Afterwards, measure length B1 of
the first wall. The surface is
automatically calculated and
indicated. The last length
measurement value is indicated
