Notes on the addition:
– Mixed length, area and volume values cannot
be added together. For example, when a
length and area value are added, "ERROR"
briefly appears on the display after pressing
the result button 5. Afterwards, the measur-
ing tool switches back to the last active
measuring mode.
– For each calculation, the result of one meas-
urement is added (e.g. the volume value); for
continuous measurements, this would be the
displayed measured value in result line c. The
addition of individual measured values from
the measured-value lines a is not possible.
– For time-delayed length measurements and
when in mark-out mode, additions are not
possible; when changing to these modes, be-
gun additions are interrupted.
Subtracting Measured Values
To subtract measuring val-
ues, press minus button 12;
For confirmation, "–" is indi-
cated on the display. The fur-
ther procedure is analog to
"Adding Measured Values".
Working Advice
General Information
The reception lens 26 and the laser beam outlet
27 must not be covered when taking a measure-
ment.
The measuring tool must not be moved while tak-
ing a measurement (except for continuous meas-
urements, minimum/maximum measurements
and when in mark-out mode). Therefore, place
the measuring tool, as far as this is possible,
against or on a firm stop or supporting surface.
Influence Effects on the Measuring Range
The measuring range depends upon the light
conditions and the reflection properties of the
target surface. For improved visibility of the
laser beam when working outdoors and when
the sunlight is intense, use the laser viewing
glasses 31 (accessory) and the laser target plate
32 (accessory), or shade off the target surface.

Influence Effects on the Measuring Result
Due to physical effects, faulty measurements
cannot be excluded when measuring on differ-
ent surfaces. Included here are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal,
glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural
stone).
If required, use the laser target plate 32 (acces-
sory) on these surfaces.
Furthermore, faulty measurements are also pos-
sible when sighting inclined target surfaces.
Also, air layers with varying temperatures or
indirectly received reflections can affect the
measured value.
Measuring with the Positioning Pin
(see figures B, C, F and G)
The positioning pin 18 is suitable for measuring
out of corners (diagonal within a space) or from
hard to reach areas, such as from roller-shutter
rails.
Press on the positioning pin latch 1 to fold it in
or out, or change its position.
For measurements starting from outer corners,
fold the positioning pin aside; for measure-
ments from the rear edge of the positioning pin
on, fold it out to the rear.
For measurements with the positioning pin, ad-
just the reference plane accordingly by pressing
button 8 (for measurements with the position-
ing pin aside, set to measuring from the rear
edge of the measuring tool).
Aligning with the Spirit Level
The spirit level 14 allows for simple levelling of
the measuring tool. This allows for easier sight-
ing of target surfaces, especially over longer dis-
tances.
In combination with the laser beam, the spirit
level 14 is not suitable for levelling.
