Warning of laser radiation
Laser class2, Pmax.: <1mW, λ: 400-700nm,
EN60825-1:2014
Do not look directly into the laser beam or the opening
from which it emerges.
Never point the laser beam at people, animals or
reflective surfaces. Even brief eye contact can lead to
eye damage.
Examining the laser output aperture by use of optical
instruments (e.g. magnifying glass, magnifiers and the
like) entails the risk of eye damage.
When working with a laser of class2, observe the
national regulations on wearing eye protection.
Warning
Risk of suffocation!
Do not leave the packaging lying around. Children may
use it as a dangerous toy.
Warning
The device is not a toy and does not belong in the
hands of children.
Warning
Dangers can occur at the device when it is used by
untrained people in an unprofessional or improper way!
Observe the personnel qualifications!

device.
Information about the device
Device description
The laser distance measuring device BD22 is used to determine
distances, areas and volumes in interior spaces. Indirect
measurements (e.g. height measurements of walls or furniture)
are carried out using the Pythagoras function.
The integrated measuring wheel enables the measurement of
curved lines, curves and circumferences. The timer allows to
perform delayed measurements after10seconds.
The device is equipped with separate operating elements for the
different measuring functions. The multi-line, backlit display
indicates the determined values and measuring functions.
Measured values can be added or subtracted and up
to50measurements can be retrieved from the data memory.
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.

Adjusting the reference point
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. Please proceed as
follows:
1. Press the button(8) to relocate the reference point to
the front end of the device.
ðAn acoustic signal is emitted each time the reference
point is relocated. In addition, the reference point
display(24) indicates the selected reference point.
When switching the device off and then on again, the reference
point will automatically be relocated to the rear end of the
device.
Changing the units
Press the Unit/ button(11) for a long time to switch between
the units for the measured values. You can set the following
indications one after the other:
• 0.000m (indication in metres, accuracy1mm)
• 0.00 m (indication in metres, accuracy1cm)
• 0.01 ft (indication in feet, accuracy 1/10ft)
• 0' 0"1/8 (indication in feet and 1/8inch, accuracy 1/8inch)
• 0.1in (indication in inches, accuracy 1/10inch)
• 0 1/8in (indication in inch and 1/8inch, accuracy 1/8inch)
Calling up a measured value in the device history
The device automatically saves the last 50measured values.
The saved measured values can be called up as follows:
1. Press the button(8) for a long time to call up the history.
