Upon completion of the third mea-
surement, the volume is automatical-
ly calculated and displayed in the re-
sult line 

c

. The individual measured 

values 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 individual 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 distanc-
es 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 measurement are exactly 
adhered to (Pythagorean Theorem).

Pay attention that the reference point of the measurement 
(e. g. the rear edge of the measuring 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 measuring modes are 
available. Each measuring mode can be used for determining 
different distances. To select the measuring mode, press the 
function-mode button 

3

 until the symbol of the desired mea-

suring mode is indicated on the display.

a) Simple Pythagoras Measurement (see figure H)

Press the function-mode button 

3

 until the indication for sim-

ple Pythagoras measurement 

 appears on the display.

Measure distances 

“1”

 and 

“2”

 in this sequence with a length 

measurement. Pay attention that a right angle exists between 
distance 

“1”

 and the sought distance 

“E”

.

Upon completion of the last measure-
ment, the result for the sought dis-
tance 

“E”

 is displayed in the result 

line 

c

. The individual measured values 

are displayed in the measured-value 
lines 

a

.

b) Double Pythagoras Measurement (see figure I)

Press the function-mode button 

3

 until the indication for dou-

ble Pythagoras measurement 

 appears on the display.

Measure distances 

“1”

, 

“2”

 and 

“3”

 in this sequence with a 

length measurement. Pay attention that a right angle exists 
between distance 

“1”

 and the sought distance 

“E”

.

Upon completion of the last measure-
ment, the result for the sought dis-
tance 

“E”

 is displayed in the result 

line 

c

. The individual measured values 

are displayed in the measured-value 
lines 

a

.

c) Combined Pythagoras Measurement (see figure J)

Press the function-mode button 

3

 until the indication for com-

bined Pythagoras measurement 

 appears on the display.

Measure distances 

“1”

, 

“2”

 and 

“3”

 in this sequence with a 

length measurement. Pay attention that a right angle exists 
between distance 

“1”

 and the sought distance 

“E”

.

Upon completion of the last measure-
ment, the result for the sought dis-
tance 

“E”

 is displayed in the result 

line 

c

. The individual measured values 

are displayed in the measured-value 
lines 

a

.

d) Trapezium Measurement (see figure K)

Press the function-mode button 

3

 until the indication for tra-

pezium measurement 

 appears on the display.

Measure distances 

“1”

, 

“2”

 and 

“3”

 in this sequence with a 

length measurement. Pay attention that the measurement of 
distance 

“3”

 starts exactly at the end point of distance 

“1”

and that a right angle exists between distances 

“1”

 and 

“2”

 as 

well as between 

“1”

 and 

“3”

.

Upon completion of the last measure-
ment, the result for the sought dis-
tance 

“E”

 is displayed in the result 

line 

c

. The individual measured values 

are displayed in the measured-value 
lines 

a

.

Time-delayed Length Measurement

Time-delayed length measurement is helpful e. g. when mea-
suring at hard to reach locations or when movements of the 
measuring tool during measuring are to be prevented.

For a time-delayed length measurement, press function-
mode button 

3

 until the indicator for time-delayed length 

measurement   appears on the display.

The time period from the actuation until the measurement 
takes place is displayed in the measured-value line 

a

. The time 

period can be adjusted between 1 s and 60 s by pressing the 
plus button 

6

 or the minus button 

12

.

Then press the measuring button 

7

 to 

switch the laser beam on and aim at 
the target point. Press the measuring 
button 

7

 again to actuate the mea-

surement. The measurement takes 
place after the set time period. The 
measured value is displayed in the re-
sult line 

c

.

The addition and subtraction of measuring results as well as 
minimum/maximum measurements are not possible for time-
delayed length measurements.

Wall Surface Measurement (see figure L)

The wall surface measurement is used to determine the sum 
of several individual surfaces with a common height.
