Intended U e
A embly
Inserting/changing the
batteries
It is recommended that you use alkaline
manganese batteries to operate the
measuring tool.
– Insert the batteries (see figure 1). When
inserting the batteries, ensure that the
polarity is correct according to the
illustration on the inside of the battery
compartment.
The battery warning (h) is shown on the
display when the battery voltage is
weakening.
When the battery symbol first appears on
the display, measurements can be made for
approx. another 15 minutes.
When the battery symbol flashes, you have
to replace the batteries because
measurements are no longer possible.
Always replace all batteries at the same
time. Only use batteries from one brand
and with identical capacity.
Remove the batteries from the laser
measure when not using it for extended
periods. When storing for extended periods,
the batteries can corrode and discharge
themselves.
uDo not use lithium-ion batteries. This
may result in damage to the measuring
tool.
Digital laser measure
The measuring tool is intended for
measuring distances, lengths, heights and
clearances, and for calculating areas. The
measuring tool is suitable for measuring
indoors.
Tape adapter
The tape adapter is intended for use in
combination with the 3Z Laser Measurer for
measuring circumferences (e.g. of vases,
pipes, etc.) and lengths of freestanding
objects (e.g. televisions, shelves, etc.) in
interior areas.
Wheel adapter
The wheel adapter is intended for use in
combination with the 3Z Laser Measurer for
measuring distances between two points
(e.g. lengths of material) in interior areas.
B) In unfavourable conditions, e.g. with extremely bright interior lighting, a poorly reflecting
surface or a room temperature that deviates significantly from 77 °F (25 °C), the deviation can
be a maximum of ±5/16 inch at a distance of 65 ft. In favourable conditions, an additional
deviation of ±0.038 inch / 65 ft needs to be taken into account.
C) Non-conductive pollution only, whereby occasional temporary conductivity caused by
condensation is expected.

Do not leave the
switched-on laser
measure unattended and switch the laser
measure off after use. Other persons could
be blinded by the laser beam.
Protect the laser measure against moisture
and direct sun light.
Do not subject the laser measure to
extreme temperatures or variations in
temperature. As an example, do not leave it
in vehicles for a long time. In case of large
variations in temperature, allow the laser
measure to adjust to the ambient
temperature before putting it into
operation. In case of extreme temperatures
or variations in temperature, the accuracy of
the laser measure can be impaired.
Avoid heavy impact to or falling down of
the laser measure. After severe exterior
effects to the laser measure, it is
recommended to carry out an accuracy
check (see “Accuracy Check of the Distance
Measurement”, page 10) each time before
continuing to work.
Switching the Laser Measure
on/off
– To switch on the measuring tool, briefly
press the measuring button (1). When the
measuring tool is switched on, the laser
beam is switched on. The indicator (d)
flashes on the display.
– To switch off the measuring tool, hold
down the measuring button (1).
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.
Measuring Process
A continuous measurement is performed
after the measuring tool has been switched
on. The current measured value (a) is
shown on the bottom line of the display
(see figure 2). During continuous
measurement, the measuring tool can be
moved relative to the target and the current
measured value (a) will be updated approx.
every 0.5 seconds on the bottom line of the
display (see figure 3). The indicator (d)
flashes on the display.
The rear edge of the measuring tool is the
reference level for the measurement ( ).
(See figure 4)
Measuring Length
– Press the measuring button (1) to stop
the measuring process. The laser beam is
switched off and the current measured
value (a) is displayed.
– Press the measuring button (1) again to
switch the laser back on and continue
measuring. The current measured value
(a) is shown on the bottom line of the
display, while the previous measured
value (b) is displayed above it.

Area Measurement
– Press the measuring button (1) twice in
quick succession to multiply the last two
measurements together (see figure 5).
The indicator (f) appears on the
display and the area measurement is
shown.
Press the measuring button (1) twice in
quick succession again to display the last
two measurements.
If no button on the measuring tool is
pressed for approx. 5 mins, the measuring
tool will automatically switch itself off to
preserve battery life.
uDo not direct the laser beam at persons
or animals and do not stare into the
laser beam yourself (even from a
distance).
General Advice
The reception lens (7) and the laser beam
output (8) must not be covered during the
measuring process.
The measurements are taken at the centre
of the laser beam, even when the laser is
pointed at surfaces diagonally.
In order to get an accurate measurement,
the laser measure must not be moved while
taking a measurement. Therefore, place the
laser measure, as much as possible, against
or on a firm stop or supporting surface. To
record the current measurement value on
the display, press the measuring button (1)
(see also "Measuring Length" on page 9).
Influence on the Measuring Range
The measuring range depends on the light
conditions and the reflection properties of
the target surface.
Influence on the Measuring Result
Due to physical effects, faulty
measurements cannot be excluded when
measuring on different surfaces which
include:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal,
glass),
– Porous surfaces (e.g. insulation
materials),
– Structured surfaces (e.g., roughcast,
natural stone).
Also, air layers with varying temperatures or
indirectly received reflections can affect the
measured value.
Accuracy Check of the
Distance Measurement
The accuracy of the distance measurement
can be checked as follows:
– Select a permanent measuring section
with a length of approx. 3 ft to 33 ft (1 m
to 10 m); its length must be precisely
known (e.g. the width of a room or a door
opening). The measuring distance must
be indoors; the target surface for the
measurement must be smooth and reflect
well.
– Measure the distance 10 times after
another.
The deviation of the individual
measurements from the mean value must
not exceed ±1/8” (±3.0mm). Log the
measurements, so that you can compare
their accuracy at a later point of time.
