To end the minimum/maximum measurement, 
briefly press the measuring button 

7

. Pressing 

the measuring button again starts a new meas-
urement.
The minimum/maximum measurement can also 
be used for length measurements within other 
measuring modes (e. g. area/surface measure-
ment). For this, press button 

13

 once for mini-

mal measurement and twice for maximal meas-
urement each time when determining individual 
measured values. Then press the measuring 
button 

7

 to switch the laser beam on. Move the 

measuring tool in such a manner that the de-
sired minimum or maximum value is measured, 
and press the measuring button 

7

 to take over 

the minimum or maximum value into the current 
calculation.
For time-delayed length measurements and 
when in mark-out mode, minimum/maximum 
measurements are not possible.
The minimum/maximum measurement auto-
matically switches off after 5 min.

Area Measurement

For area/surface measurements, press button 

4

until the indicator for area measurement   
appears on the display.
Afterwards, measure the length and the width, 
one after another, in the same manner as a 
length measurement. The laser beam remains 
switched on between both measurements.

Upon completion of the sec-
ond measurement, the sur-
face is automatically calculat-
ed and displayed in the result 
line 

c

. The individual meas-

ured values are displayed in 
the measured-value lines 

a

.

Volume Measurement

For volume measurements, press button 

4

 until 

the indicator for volume measurement 

appears on the display.
Afterwards, measure the length, width and the 
height, one after another, in the same manner as 
for a length measurement. The laser beam re-
mains switched on between all three measure-
ments.

Upon completion of the third 
measurement, the volume is 
automatically calculated and 
displayed in the result line 

c

. 

The individual measured val-
ues are displayed in the 
measured-value lines 

a

.

Values above 999 999 m

3

 cannot be indicated; 

“ERROR”

 and 

“– – – – ”

 appear on the display. 

Divide the volume to be measured into indivi-
dual measurements; their values can then be 
calculated separately and then summarized.

Indirect Length Measurement 
(see figures H – K)

The indirect length measurement is used to 
measure distances that cannot be measured 
directly because an obstacle would obstruct the 
laser beam or no target surface is available as a 
reflector. Correct results are achieved only when 
the right angles required for the respective meas-
urement are exactly adhered to (Pythagorean 
Theorem).
Pay attention that the reference point of the 
measurement (e. g. the rear edge of the measur-
ing tool) remains exactly at the same location for 
all individual measurements within a measuring 
sequence (exception: trapezium measurements).
The laser beam remains switched on between 
the individual measurements.
For indirect length measurements, four measur-
ing modes are available. Each measuring mode 
can be used for determining different distances. 
To select the measuring mode, press the func-
tion-mode button 

3

 until the symbol of the de-

sired measuring mode is indicated on the display.
