To delete the currently displayed measured-value list entry, 
briefly press button 

16

. To delete the complete measured-

value list, press and hold the button for the measured-value 
list 

15

 and at the same time briefly press button 

16

.

Deleting Measured Values

Briefly pressing button 

16

 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 wall surface measurement mode, briefly pressing button 

16

 the first time deletes the last individually measured value; 

pressing the button a second time deletes all lengths 

B

X

, and 

pressing the button a third time deletes all room heights 

A

.

Adding Measured Values

To add measured values, firstly carry out any measurement or 
select an entry from the measured-value list. Then press the 
plus button 

6

. For confirmation, 

“+”

 appears on the display. 

Then carry out a second measurement or select another entry 
from the measured-value list.

To call up the sum of both measure-
ments, press the result button 

5

. The 

calculation is indicated in the mea-
sured-value lines 

a

, and the sum in 

the result line 

c

.

After calculation of the sum, further 
measured values or measured-value 

list entries can be added to this result when pressing the plus 
button 

6

 prior to each measurement. Pressing the result but-

ton 

5

 ends the addition.

Notes on the addition:

– Mixed length, area and volume values cannot be added to-

gether. For example, when a length and area value are add-
ed, 

“ERROR”

 briefly appears on the display after pressing 

the result button 

5

. Afterwards, the measuring tool switch-

es back to the last active measuring mode.

– For each calculation, the result of one measurement is 

added (e. g. the volume value); for continuous measure-
ments, this would be the displayed measured value in re-
sult 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, begun additions are interrupted.

Subtracting Measured Values

To subtract measuring values, press 
minus button 

12

; for confirmation, 

“– ”

 is indicated on the display. The 

further procedure is analog to “Add-
ing Measured Values”.

Working Advice

General Information

The reception lens 

26

 and the laser beam outlet 

27

 must not 

be covered when taking a measurement.

The measuring tool must not be moved while taking a mea-
surement (except for continuous measurements, 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 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 

32

 (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.

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 posi-
tioning pin aside; for measurements from the rear edge of the 
positioning pin on, fold it out to the rear.

For measurements with the positioning pin, adjust the refer-
ence plane accordingly by pressing button 

8

 (for measure-

ments with the positioning 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 sighting of target surfaces, espe-
cially over longer distances.

In combination with the laser beam, the spirit level 

14

 is not 

suitable for levelling.
