In this manner, you can measure any number of further
lengths B
height A.
The condition for a correct area/surface calculation is that the
first measured length (in the example the room height A) is
identical for all partial surfaces.
To restart the wall surface measurement, press button 11
twice.
Deleting Measured Values
Briefly pressing button 14 deletes the last individual measur-
ing value determined in all measuring functions. Briefly press-
ing the button repeatedly deletes the individual measured val-
ues in reverse order.
In the wall surface measurement mode, briefly pressing but-
ton 14 the first time deletes the last individually measured
value; pressing the button a second time deletes all lengths
B .

Memory Functions

When switching off the measuring tool, the value in the mem-
ory is retained.
In the wall surface measurement mode, the total surface value
can be stored; in the minimum and maximum measuring
mode, the minimum and maximum value can be stored corre-
spondingly. Storing individual measuring values within these
functions is not possible.
Storing/Adding Measured Values
If a value is already stored in the memory, the new value is
added to the memory contents, however, only when the
measures of unit correspond.
As an example, when an area value is in the memory and the
current measured value is a volume value, the addition cannot
take place. "Error" briefly flashes in the display.
Subtracting Measured Values
Push the memory subtraction button 12 in order to subtract
the current measured value from the memory value. As soon
as a value has been subtracted, "M" is indicated in the display
and the "–" behind it briefly flashes.

Now, measure length B
ond wall. The individual measuring
value indicated at the bottom of
the display is added to length B
and the sum of both lengths is mul-
tiplied with the stored length A.
The total surface value is indicated
at the top in the display.

Push the memory add button 3 in
order to store the current meas-
ured value – a length, area or vol-
ume value, depending on the cur-
rent measuring function. As soon
as a value has been stored, "M" is
indicated in the display and the "+"

Deleting the Memory
To delete the memory contents, first push the memory re-
trieve button 2, so that "M=" is indicated in the display. Then
briefly press button 14; "M" is no longer indicated in the dis-
play.

Working Advice

General Information
The reception lens 22 and the laser beam outlet 21 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a meas-
urement (except for the functions minimum/maximum meas-
urement incl. continuous measurement). Therefore, place
the measuring tool, as far as this is possible, against or on the
measuring points.
Measurement takes place at the centre of the laser beam,
even when target surfaces are sighted at an incline.
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 24 (ac-
cessory) and the laser target plate 25 (accessory), or shade
off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be ex-
cluded when measuring on different 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 25 (accessory) on these
surfaces.
Furthermore, faulty measurements are also possible when
sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly re-
ceived reflections can affect the measured value.

Push the memory retrieve button 2
in order to display the value stored
in the memory. "M=" is indicated
in the display. When the memory
contents "M=" is indicated in the
display, it can be doubled by push-
ing the memory add button 3 or set
to zero by pushing the memory
subtract button 12.
