A) When measuring from the back edge of the measuring tool, this applies for
high reflectivity of the target (e.g. a wall painted white), weak background
lighting and a 20 °C operating temperature; a distance-dependent deviation of
±0.05 mm/m must additionally be factored in.
B) When measuring from the back edge of the measuring tool, this applies for
high reflectivity of the target (e.g. a wall painted white), strong background
lighting, 20 °C operating temperature and high elevation. In addition, a
deviation of ±0.15 mm/m must be taken into account, depending on the distance.
C) Only non-conductive deposits occur, whereby occasional temporary
conductivity caused by condensation is expected.
The serial number
(8) on the type plate is used to clearly identify your measuring tool.
Inserting/Changing the Battery
Using alkali-manganese or nickel metal hydride rechargeable batteries
(especially at low operating temperatures) is recommended for operation of the
measuring tool.
With 1.2 V rechargeable batteries, more measurements may be possible than with
1.5 V batteries, depending on the capacity.
Open the battery compartment cover.
Insert the batteries/rechargeable batteries.
Always replace all the batteries/rechargeable batteries at the same time. Only
use batteries/rechargeable batteries from the same manufacturer and which have
the same capacity.
When inserting the batteries, ensure that the polarity is correct according to
the illustration on the inside of the battery compartment.
When the empty battery symbol first appears on the display and flashes, only a
limited number of measurements is still possible. Replace the batteries or
reusable batteries.
Take the batteries out of the measuring tool when you are not using it for a
prolonged period of time. The batteries can corrode and self-discharge during
prolonged storage.
Operation
Starting Operation
- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be dazzled by the laser beam.
- Protect the measuring tool from moisture and direct sunlight.
- Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
- Avoid substantial knocks to the measuring tool and avoid dropping it. After strong external influences on the measuring tool, you should always carry out an accuracy check (see “Accuracy Check”, page 16) before further work.
Switching On and Off
Press the button to switch on the measuring tool.
Press and hold the button to switch off the measuring tool.
If no button on the measuring tool is pressed for approx. 5 min, the measuring
tool will switch off automatically to preserve the non-rechargeable batteries.
Measuring Process
When switching on for the first time, the measuring tool will be in the length
measurement function. When switching on every subsequent time, the measuring
tool will be in the measuring function that was last used.
The rear edge of the measuring tool is always the reference level for the
measurement.
Apply the measuring tool to the point at which you want to start the
measurement (e.g. wall).
Press the button to switch on the laser beam.
Target the target surface with the laser beam.
Briefly press the button again to start the measurement.
The duration of the measurement depends on the distance, the lighting
conditions and the reflective properties of the target surface. Upon
completion of the measurement, the laser beam will automatically switch off.
The measuring tool must not be moved during a measurement. Therefore, place
the measuring tool, as far as this is possible, against or on a firm stop or
supporting surface.=
The reception lens (10) and the laser beam output (11) must not be covered
during the measuring process.
Influences on the Measuring Range
The measuring range depends on the lighting conditions and the reflective
properties of the target surface.
For better visibility of the laser beam in bright extraneous light, use the
laser viewing glasses (13) (accessory) and the laser target plate (12)
(accessory), or shade the target surface.
Influences on the Measurement Result
Due to physical effects, incorrect measurements are possible when measuring on
various surfaces. These include:
– Transparent surfaces (e.g. glass, water)
– Reflective surfaces (e.g. polished metal, glass)
– Porous surfaces (e.g. insulation materials)
– Structured surfaces (e.g. roughcast, natural stone)
If necessary, use the laser target plate (12) (accessory) on these surfaces.
Incorrect measurements are also possible on slanted target surfaces.
Likewise, layers of air with different temperatures or indirectly received
reflections can influence the measured value.
Changing the Unit of Measurement m/ft
The default unit of measurement is “m” (metres).
Switch on the measuring tool .
Press and hold the button until the menu for selecting the unit of measurement
is displayed.
Press the button to change the unit of measurement.
To confirm the selection, press the button.
The selected setting remains saved after you switch off the measuring tool.
Measuring functions
Selecting/Changing Measuring Function
You will find the following
functions in the Functions menu:
– Length measurement
– Continuous measurement
– Area measurement
Press the button to open the Functions menu.
Select the required measuring function with the button.
To confirm the selection, press the button.
Length Measurement
Press the button to open the Functions menu.
Select the length measurement and confirm the selection with the button.
Briefly press the button to switch on the laser.
Press the button to start the measurement.
The measured value is displayed in the result line (f) at the bottom of the
display.
Repeat the above-mentioned steps for each subsequent measurement. If several
length measurements are taken in a row, the results of the last measurements
are displayed in the measured value lines (e). The last measured value is at
the bottom of the display, the penultimate measured value is above it, and so
on.
Continuous Measurement
During continuous measurement, the measured value is continually updated. You
can, for example, move a required distance away from a wall while reading off
the current distance at all times.
Press the button to open the Functions menu.
Select continuous measurement and confirm the selection with the button.
The laser is permanently switched on.
Move the measuring tool until the required distance is shown on the display.
You can interrupt the continuous measurement by briefly pressing the button.
Press the button again to continue the continuous measurement. The current
measured value is displayed in large figures for better readability.
Continuous measurement switches off automatically after 4 min.
Area Measurement
Press the button to open the Functions menu.
Select area measurement and confirm the selection with the button.
Briefly press the button to switch on the laser.
Press the button to start the first measurement, e.g. the length of a room.
Press the button to start the second measurement, e.g. the width of a room.
After the second measurement has been completed, the area will be
automatically calculated and displayed. The result is displayed in the result
line (f). The individual measured values are in the measured value lines (e).
Accuracy Check
Regularly check the accuracy of the measuring tool.
Accuracy Check of the Distance Measurement
For the accuracy check, the measurement should be taken under favourable
conditions, i.e. the measuring section should be indoors and the target
surface for the measurement should be smooth and reflect well (e.g. a white-
paintedwall).
Select a measuring section of approx. 1 to 10 m long, the length of which you
know exactly (e.g. room width, doorway).
Measure the section 10 times in succession.
The deviation of individual measurements from the exact known value may be
maximum ±2 mm throughout the entire measuring section under favourable
conditions. Log the measurements, so that you can compare their accuracy at a
later point of time.
Error Message
If a measurement cannot be performed correctly, the error message Error will
appear in the display.
Try to perform the measuring process again.
If the error message appears again, switch the measuring
tool off and back on, and start the measurement again.
The measuring tool monitors correct operation in every measurement. If a
defect is detected, the display will indicate only the symbol shown opposite
and the measuring tool switches itself off. In this case, have the measuring
tool checked by an after-sales service agent for Bosch power tools.
