Information about the device
Device description
The laser distance measuring device is used to determine
distances, areas and volumes in interior spaces. Indirect
measurements are carried out employing the Pythagoras
function.
The multi-line, illuminated displayindicates the determined
values.
Owing to the dust- and splash-proof housing (IP54), the device
is also suited for use on construction sites.
Measuring distance
The range of the device can be gathered from the Technical
data chapter. Under certain conditions – e.g. at night, in twilight
or when the target is hidden in the shade – greater distances
are possible even without target plate. During the day use a
target plate to increase the distance for poorly reflecting targets.
Target surfaces
There might be measurement errors when the laser encounters
colourless liquids (e.g. water), dust-free glass, styrofoam or
other semi-permeable materials. The measurement result may
also be falsified if the laser encounters a high-gloss surface and
is deflected by it. Non-glossy, non-reflective or dark surfaces
can extend the measurement duration.
Caution
Keep a sufficient distance from heat sources.
Notice
To prevent damages to the device, do not expose it to
extreme temperatures, extreme humidity or moisture.
Notice
Do not use abrasive cleaners or solvents to clean the
device.
The three upper measurement value displays show the past three
measured values, the minimum and maximum value or the measured
values to be added or subtracted.

1. Briefly press the Switch-on/measurement button(7).
ð The display is switched on and the device is ready for
operation.
Switch-off
1. Press the Switch-off button(10) for a long time.
ð The display is switched off.
Basic settings
Aborting the measurement and deleting the display
1. Briefly press the Delete button(10) to abort the current
measurement or to delete the displayed measured values
one at a time. The laser switches off for this purpose.
Setting the reference value
The device always measures the total distance starting at the
reference point. This means that if the rear end of the device is
set as reference point, the length of the device will be part of
the measurement. By default the reference point is set to the
rear of the device. You can, however, also relocate the
reference point to the front part of the device.
To do so, please proceed as follows:
1. Press the Reference button(9) for a long time to relocate
the reference point to the front end of the device.
ð The Reference value front indication(23) appears on
the display.
2. Proceed the same way to relocate the reference value to the
end of the end piece.
When switching the device off and then on again, the reference
value will automatically be relocated to the rear end of the
device.
Changing the units
1. Press the Unit button(8) for a long time to switch between
the units for the measured values. Available units are ft, in
and m.
Calling up a measured value in the device history
The device automatically saves the last 10 measured values.
The saved measured values can be called up as follows:
1. Briefly press the Function button (8) five times to call up the
history.
ð The History indication(18) appears on the display.
2. Briefly press the Plus/Minus button(9) to navigate through
the history and call up the saved measured values.
3. You can return to the normal measuring menu by briefly
pressing the Delete button(10) or the Measurement
button(7).
Carrying out measurements
Warning of laser radiation
Laser class2, P max.: > 1mW, λ: 650nm,

Do not look directly into the laser beam or the opening
from which it emerges.

Info
Note that moving from a cold area to a warm area can
lead to condensation forming on the device's circuit
board. This physical and unavoidable effect can falsify
the measurement. In this case, the display shows
either no measured values or they are incorrect. Wait a
few minutes until the device has become adjusted to
the changed conditions before carrying out a
measurement.
Carrying out single distance measurement
1. Briefly press the Switch-on/measurement button(7) to
activate the laser if it is switched off.
2. Point the laser at the target area.
3. Briefly press the Switch-on/measurement button(7) again
to perform a distance measurement.
ð The measured value is immediately indicated on the
2. To add a measured value, briefly press the Plus/Minus
button(9) one time.
To subtract a measured value, briefly press the Plus/Minus
button(9) twice.
3. Press the Switch-on/measurement button(7) to determine
the next measured value.
ð The overall result will be indicated in the lower
measurement value display. The individual measured
values will be indicated in the upper measurement
value displays.
Info
If you want to add or subtract further measured values,
please note that you first have to confirm the current
measured values with the Switch-on/measurement
button(7).
Performing an area measurement
1. Briefly press the Function button(8) one time.
ð The symbol
for area measurement appears on the
display.
2. Briefly press the Switch-on/measurement button(7) to carry
out the first measurement (e.g.length).
3. Briefly press the Switch-on/measurement button(7) again
to carry out the second measurement (e.g.width).
ð Upon pressing the Switch-on/measurement button(7)
for the second time the device calculates the area and
displays this value in the lower measurement value
display. The most recently measured value will be
indicated in one of the upper measurement value
displays.
Performing a volume measurement
1. Briefly press the Function button(8) twice.
ð The symbol
for volume measurement appears on
the display.
ð The side to be measured in each case is indicated on
the display by flashing.
2. Briefly press the Switch-on/measurement button(7) to carry
out the first measurement (e.g.length).
3. Briefly press the Switch-on/measurement button(7) again
to carry out the second measurement (e.g.width).
4. Briefly press the Switch-on/measurement button(7) again
to carry out the third measurement (e.g.height).
ð Upon pressing the Switch-on/measurement button(7) for
the third time the device independently calculates the
volume and displays this value in the lower measurement
value display.
Performing a non-stop / min and max measurement
Use the non-stop measuring function to correlate
measurements e.g. with construction drawings. With this
measurement method the device can be moved closer toward
the target with the measured value being recalculated roughly
every 0.5 seconds. The corresponding maximum and minimum
measured values are displayed in the first and second line
respectively.
For instance, you can direct the laser beam at a wall and then
retreat from it step by step. Keep reading the measured values
until the desired distance is achieved.
1. Press the Switch-on/measurement button(7) for a long time
until the max(21), min(19) and Δ indications(17) appear on
the display.
2. With reference to the target point, move the device slowly
back and forth as well as up and down (e.g.in a corner).
3. Briefly press the Switch-on/measurement button(7) to
terminate the non-stop measurement.
ð The maximum and minimum measured values and the
difference (Δ) between these two are indicated on the
display. Additionally, the last measured value will be
displayed in the bottommost line.
Using this method the length of an unknown straight-line
segment can be determined via the Pythagorean Theorem. This
method is suitable for e.g. height measurements.
Twofold indirect height measurement
This method is suitable for e.g. height measurements.
1. Briefly press the Function button(8) four times.
Measurement requirements:
•The device is aligned horizontally to the lowest point (B) of
the line segment to be determined.
•The reference point is located at the rear of the device.
