Operation

Initial Operation

f

Do not leave the switched on measuring tool unattend-

ed and switch the measuring tool off after use. 

Other 

persons could be blinded by the laser beam.

f

Protect the measuring tool against moisture and direct 

sun light.

f

Do not subject the measuring tool to extreme tempera-

tures or variations in temperature. 

As an example, do 

not leave it in vehicles for longer periods. In case of large 

variations in temperature, allow the measuring tool to ad-

just to the ambient temperature before putting it into oper-

ation.

f

Avoid heavy impact to or falling down of the measuring 

tool. 

After severe exterior effects to the measuring tool, it 

is recommended to carry out an accuracy check (see “Ac-

curacy Check of the Measuring Tool”, page 10) each time 

before continuing to work.

Switching On and Off

To 

switch on

 the measuring tool, briefly press the On/Off but-

ton 

13

 or measuring button 

9

. When switching on the measur-

ing tool, the laser beam is not switched on yet.
To 

switch off

 the measuring tool, press the On/Off button 

13

for a few seconds.
If none of the measuring tool buttons are pressed for approx. 

5 minutes, the measuring tool switches off automatically in 

order to extend the service life of the battery.
When a measured value has been stored, it is retained in auto-

matic switch-off mode. When switching on the measuring tool 

again, 

“M”

 is indicated in the display.

Measuring Procedure

After switching on, the measuring tool is in the length meas-

urement mode. Other measuring modes can be switched to 

by pressing the respective function/mode button (see “Meas-

uring Functions”, page 13).
After switching on, the rear edge of the measuring tool is pre-

set as the reference level for the measurement. To change the 

reference level, see “Selecting the Reference Level”, page 13. 
Upon selection of the measuring function and the reference 

level, all further steps are carried out by pushing the measur-

ing button 

9

.

With the reference level selected, place the measuring tool 

against the desired measuring line (e. g. a wall).
Briefly press the measuring button 

9

 to switch on the laser 

beam.

f

Do not point the laser beam at persons or animals and 

do not look into the laser beam yourself, not even from 

a large distance.

Aim the laser beam at the target surface. Briefly press the 

measuring button 

9

 again to initate the measurement.

In the continuous measurement mode, the measurement be-

gins immediately upon switching on the function.

Typically, the measured value appears after 0.5 and latest af-

ter 4 seconds. The duration of the measurement depends on 

the distance, the light conditions and the reflection proper-

ties of the target surface. The end of the measurement is indi-

cated by a signal tone. The laser beam is switched off auto-

matically upon completion of the measurement.
When no measurement has taken place approx. 20 seconds 

after sighting, the laser beam is switched off automatically to 

save the batteries.

Selecting the Reference Level (see figure B – C)

For the measurement, it is possible to select between two dif-

ferent reference levels:
– For measurements starting from the rear edge of the meas-

uring tool (e. g., when placing against a wall), press button 

12

.

– For measurements starting from the front edge of the 

measuring tool (e. g., when measuring from onward from a 

table edge), press button 

1

.

The selected reference level is indicated on the display. Each 

time after switching on the measuring tool, the rear end of the 

measuring tool is preset as the reference level.

Measuring Functions

Length Measurement

For length measurement, push button 

5

. The indicator for 

length measurement appears in the display  .

Press the measuring button 

9

 once 

for sighting and once more to take 

the measurement.
The measured value is indicated at 

the bottom in the display.

Area Measurement

For area measurements, push button 

4

. The indicator for area 

measurement appears in the display  .
Afterwards, measure the length and the width, one after an-

other, in the same manner as a length measurement. The laser 

beam remains switched on between both measurements.

After taking the second measure-

ment, the area/surface is automat-

ically calculated and displayed. 

The last individual measured value 

is indicated at the bottom in the 

display, while the final result is 

shown at the top.

Volume Measurement

For volume measurements, push button 

10

. The indicator for 

volume measurement appears in the display 

.

Afterwards, measure the length, width and the height, one af-

ter another, in the same manner as for a length measurement. 

The laser beam remains switched on between all three meas-

urements.
