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 wall surface measurements, press the function-mode but-
ton 

3

 until the indicator for wall surface measurement 

 ap-

pears on the display.

Measure the room height 

A

 as for a length measurement. The 

measured value (

“cst”

) is displayed in the top measured-

value line 

a

. The laser remains switched on.

Afterwards, measure length 

B

1

 of the 

first wall. The surface is automatically 
calculated and displayed in the result 
line 

c

. The length measurement value 

is displayed in the centre measured-
value line 

a

. The laser remains 

switched on.

Now, measure length 

B

2

 of the sec-

ond wall. The individually measured 
value displayed in the centre mea-
sured-value line 

a

 is added to the 

length 

B

1

. The sum of both lengths 

(

“sum”

, displayed in the bottom 

measured-value line 

a

) is multiplied 

with the stored height 

A

. The total surface value is displayed 

in the result line 

c

.

In this manner, you can measure any number of further 
lengths 

B

X

, which are automatically added and multiplied with 

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.

For a new wall surface measurement with new room height 

A

, 

press button 

16

 three times.

Mark-out Mode (see figure M)

Mark-out mode is used for marking off a fixed length (mark-
out value), which can either be measured or entered. It is 
helpful for, e. g., marking partition spaces for drywalls.

To activate the mark-out mode, press the function-mode but-
ton 

3

 until the mark-out mode indication   appears on the 

display.

The mark-out value can be adjusted as follows:

– To enter a known value, press the plus button 

6

 or the mi-

nus button 

12

 until the desired value is displayed in the up-

per measured-value line 

a

. When pressing and holding the 

plus button 

6

 or minus button 

12

, the values will continu-

ously skip through. The laser is not activated yet.

– For measuring the mark-out value, briefly press the mea-

suring button 

7

 once for sighting and once more for meas-

uring. Afterwards, the laser beam remains switched on.

– The measured or entered mark-out value can be corrected 

by pressing the plus button 

6

 or the minus button 

12

.

After determining the mark-out value, press and hold the 
measuring button 

7

 to begin the measurement.

Now, move the measuring tool in the desired direction for 
marking out. The current measuring value of the complete 

measured distance is continuously displayed in the result line 

c

. The selected mark-out value continues to be displayed in 

the upper measured-value line 

a

.

The factor (

“x”

) how often the mark-out value is contained in 

the total measuring distance is displayed in the centre mea-
sured-value line, and the difference (

“dif”

) between an inte-

gral multiple of the mark-out value and the total distance is 
displayed in the bottom measured-value line 

a

.

When the total measuring distance is somewhat less than an 
integral multiple, then a negative difference and the next high-
er multiple of the mark-out value are displayed.
Move the measuring tool until the desired multiple of the mark-
out value is displayed in the centre measured-value line 

a

 and 

the difference in the bottom measured-value line is 

a

 “0.0 m”. 

Then mark off the reference point of the measurement.

Examples:
a) Positive difference:
7.4 m = (12 x 0.6 m) + 0.2 m

The mark-out value 0.6 m is con-
tained 12 x in a total distance of 
7.4 m. Additionally, the total distance 
contains a rest of 0.2 m. Reduce the 
distance between the measuring tool 
and the starting point by 0.2 m differ-
ence, and then mark off the length.

b) Negative difference:
7.0 m = (12 x 0.6 m) – 0.2 m

For a total distance of 7.0 m, 0.2 m 
are missing for the mark-out value 
0.6 m to be contained 12 x. Increase 
the distance between the measuring 
tool and the starting point by 0.2 m 
difference, and then mark off the 
length.

Briefly pressing measuring button 

7

 ends the mark-out mode. 

Pressing and holding the measuring button 

7

 restarts the 

mark-out mode anew (with the same mark-out value).

The mark-out mode automatically switches off after 5 min. 
For prior exiting of the function, press one of the measuring-
mode buttons.

List of the last Measuring Values

The measuring tool stores the last 30 measuring values and 
their calculations, and displays them in reverse order (last 
measured value first).

To recall the stored measurements, 
press button 

15

. The result of the last 

measurement is indicated on the dis-
play, along with the indicator for the 
measured-value list 

d

 as well as a 

counter for the numbering of the dis-
played measurements.

When no further measurements are stored after pressing but-
ton 

15

 again, the measuring tool switches back to the last 

measuring function. To exit the measured-value list, press 
one of the measuring-mode buttons.
