WARNING WARNING
Laser beam
Eye damage or risk of accident due to glare are possible in case of eye contact with the laser beam.
•Never look directly into a laser beam or its reflections!
•If the laser beam hits your eye, close your eyes and immediately turn your face away from the laser beam.
Normally, eyes close automatically due to the blink reflex and aversion responses take place.
•Do not point the laser beam at persons or animals.
•Do not leave the unit switched on unnecessarily.
Opening the device
Eye damage or risk of accident due to glare are possible in
case of eye contact with the laser beam when opening the
device.
•Do not open the device (except for the battery
compartment).
•Please contact your specialty retailer or the returns
management for any repairs.

The measurement is started and the measured value (L) will
be shown on the digital display.
3. Point the laser beam at the second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the measured value (W) will
be shown on the digital display.
The device calculates the area from the two measurements and the determined value will
be shown on the digital display.
Volume calculation
The volume calculation function is intended for determining the
volume of a rectangular space by measuring three measured
lengths that are perpendicular to each other.
1. Point the laser beam at the first measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value (L) will
be shown on the digital display.
3. Point the laser beam at the second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the measured value (W) will
be shown on the digital display.
5. Point the laser beam at the third measuring point (C).
6. Press the “Measurement” key.
The measurement is started and the measured value (H) will be shown on the digital
display. The device calculates the volume from the three measurements and the
determined value will be shown on the digital display.

Indirect length calculation
The indirect length calculation is intended for determining certain distances using length
measurements to various points and angle measurements of the respective axes.
Indirect length calculation 1
1. Point the laser beam at the first measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value will be
shown on the digital display.
3. Point the laser beam perpendicularly to the surface at the
second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the second measured value
will be shown on the digital display.
The device calculates the distance between the two
measuring points from the measurements and the determined
value will be shown on the digital display.
/ Indirect length calculation 2 / 3
1. Point the laser beam at the
first measuring point (A).
2. Press the “Measurement”
key.
The measurement is started
and the measured value will
be shown on the digital
display.
3. Point the laser beam at the
second measuring point (B).
4. Press the “Measurement”
key.
The measurement is started and the second measured value will be shown on the digital
display.
5. Point the laser beam perpendicularly to the surface at the third measuring point (C).
6. Press the “Measurement” key.
The measurement is started and the third measured value will be shown on the digital
display. The device calculates the distance between the measuring points A and B from the
measurements and the determined value will be shown on the digital display.

Digital spirit level (axis)
The digital spirit level (axis) is intended for measuring an angle of
an axis in relation to the horizontal and for displaying the
corresponding inclination.

2. Align the device. The axis of the device must correspond to
the axis to be checked.
The measured value will be shown on the digital display and a
digital spirit level indicates the inclination.
In horizontal position, the alignment point (“bubble”) is exactly
between the two markings and will be displayed in green.
Digital spirit level (surface)
The digital spirit level (surface) is intended for displaying an inclination of a surface in relation
to the horizontal.
1. Place the device onto the surface to be checked.
The digital spirit level indicates the inclination. In horizontal position, the alignment point
(“bubble”) is exactly within the inner marking and will be displayed in green.
