Safety instructions
All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions. Never make warning signs on the measuring tool unrecognizable. SAVE THESE IN-
STRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASUR-ING TOOL WHEN TRANSFERRING IT TO A THIRD PARTY.
- Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.
The measuring tool is delivered with a warning label (marked in the illustration of the measuring tool on the graphics page with number (14) ).
- If the text on the warning label is not in your native language, cover it with the la-bel supplied, which is in your language, before initial commissioning.
Do not direct the laser beam at persons or animals and do not look directly into the laser beam or at its reflection. Doing so could lead to blindless, or could cause accidents or damage to the eyes.
-
If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.
-
Do not make any modifications to the laser equipment.
-
Do not use the laser goggles as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
-

Technical Data
- For measurements from the rear edge of the measuring tool. The working range increases de-pending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and the brighter the laser point is to the ambient light intensity (interior spaces, twilight). For distances of less than 20 m, a retro-reflective target plate should not be used, as it can lead to measurement errors.
- For measurements from the rear edge of the measuring tool, 100% reflectivity of the target (e.g. a white wall), weak backlighting and 25 °C operating temperature. In addition, a deviation influence of ±0.05 mm/m needs to be taken into account.
- Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
- At an operating temperature of 25 °C
The serial number (11) on the type plate is used to clearly identify your measuring tool.
Fitting
Inserting/changing the batteries
It is recommended that you use alkaline manganese batteries to operate the
measuring tool.
Note that if you use 1.2 V batteries, you will not be able to perform as many
measurements as you would with 1.5 V batteries.
Push the locking mechanism (10) in the direction of the arrow to open the
battery compartment cover (9) and remove the battery compartment cover. Insert
the batteries.
When inserting, pay attention to the correct polarity according to the
representation on the inside of the battery compartment.
When the battery symbol appears on the display for the first time, at least
another 100 measurements can be taken. Once the battery symbol is empty, you
have to replace the batteries/rechargeable batteries, because measurements are
no longer possible.
Always replace all the batteries at the same time. Only use batteries from the
same manufacturer and which have the same capacity.
- Take the batteries out of the measuring tool when you are not using it for a pro-longed period of time. The batteries can corrode and self-discharge during pro-longed storage.
Operation
Start-Up
- 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 subjecting the measuring tool to violent jolts and falls. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see “Accuracy check of the measuring tool”, page 29).
Switching On and Off
To switch on the measuring tool, press the on/off button (8) or the measuring
button (4). When switching on the measuring tool, the laser beam is not
switched on.
To switch off the measuring tool, press and hold the on/off button (8)
If no button on the measuring tool is pressed for approx. five minutes, then
the measuring tool will automatically switch itself off to preserve battery
life.
Measuring process
Once switched on, the measuring tool is in the length measurement function.
Other measuring functions can be set by repeatedly pressing the button (3) or
the navigation buttons (7) [+] or (2) [–] (see “Measuring functions”, page
24).
Once the measurement function is selected by pressing the measuring button
(4), the laser beam is switched on. Once the measuring tool has been switched
on, the rear edge of the measuring tool is selected as the reference level for
measurement. To change the reference level, select (see “Selecting the
reference level (see figures A–B)”, page 24).
Place the measuring tool at the line you want to measure from (e.g. wall) with
the reference level selected.
To initiate the measurement, briefly press the measuring button (4). Then the
laser beam is switched off. To switch the laser beam on again, briefly press
the measuring but-ton (4). To initiate a further measurement, briefly press
the measuring button (4) again.
- Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
In the continuous measurement function, measurement will begin after the first
press of the measuring button (4).
The measured value typically appears within half a second and no later than
four seconds. The duration of the measurement depends on the distance, the
lighting conditions and the reflective properties of the target surface.
If no measurement has been performed within approx. 20 seconds of aim being
taken, the laser beam is switched off automatically to preserve battery life.
Selecting the reference level (see figures A–B)
You can choose between two different reference levels for the measurement:
- The rear edge of the measuring tool (e.g. when placing against walls)
- The front edge of the measuring tool (e.g. when measuring from a table edge).
To change the reference level, press the button (1) until the required reference level is shown on the display. The rear edge of the measuring tool is pre-set as the reference level every time the measuring tool is switched on.
Measuring functions
Measuring length
Select the length measurement function (see “Measuring process”, page 24).
Press the measuring button (4) once to aim at the target surface and again to
measure.
The measured value will be shown at the bottom of the display. Repeat the
above-mentioned steps for each subsequent measurement. The last four measured
values are shown on the display. The last measured value is at the bottom of
the display, the penultimate measured value is above it, and so on.
Note: Press and hold the measuring button (4) to switch to the length
measurement function from any measuring function.
Area measurement
Select the area measurement function .
Then measure the width and length one after the other as with a length
measurement. The laser beam remains switched on between the two measurements.
The distance to be measured flashes in the indicator for area measurement .
The first measured value is shown at the top of the display.
After the second measurement has been completed, the area will be
automatically calculated and displayed. The end result is shown at the bottom
of the display, while the individual measured values are shown above it.
Volume measurement
Select the volume measurement function .
Then measure the width, length and height one after the other as with a length
measurement. The laser beam remains switched on between the three
measurements. The distance to be measured flashes in the indicator for volume
measurement . After the third measurement has been completed, the volume will
be automatically calculated and displayed. The end result is shown at the
bottom of the display, while the individual measured values are shown above
it.
Continuous measurement (see figure C)
In continuous measurement mode, the measuring tool can be moved relative to
the tar-get, during which the measured value will be updated every half a
second. You can, for example, move a desired distance away from a wall while
reading off the current distance at all times.
Select the continuous measurement function .
Press the measuring button (4) to initiate the measuring process. Move the
measuring tool until the desired distance value is shown in the display below.
You can pause the continuous measurement by pressing the measuring button (4).
The current measured value will be shown at the bottom of the display. The
largest and smallest measured value appear above it. Pressing the measuring
button (4) once more will start the continuous measurement again.
Continuous measurement automatically switches off after four minutes.
Deleting measured values
In any measuring function, you can delete the most recently recorded
individual measured value by briefly pressing the on/off button (8).
Repeatedly pressing the button briefly will delete the individual measured
values in reverse order.
Adding/subtracting values
Measured values or end results can be added or subtracted.
Adding values
The following example describes the addition of areas:
Measure an area as described in the section on area measurement (see “Area
measurement”, page 25).
Press the button (7) [+]. The calculated area is shown in the centre of the display.
Press the measuring button (4) to start another area measurement. Measure the area as de-scribed in the section on area measurement (see “Area measurement”, page 25). To complete the addition, press the measuring button (4). To add more measured values, press the button (7) [+] again and repeat.
Subtracting values
To subtract values, press the button (2) [–]. The subsequent steps are the
same as for the section on adding values.
List of the last measured values/calculations
The measuring tool stores the last 10 measured values and their calculations
and dis-plays them in reverse order (most recent measured value/most recent
calculation first). Press the button (6) to display the list of measured
values.
Deleting measured values in the measured value list
Briefly press the on/off button (8) to delete the currently displayed measured
value. Press the button (6) and the on/off button (8) simultaneously to delete
all measured val-ues from the list.
Practical Advice
General advice
The reception lens (12) and the laser beam output (13) must not be covered
during the measuring process.
The measuring tool must not be moved while a measurement is being taken
(unless in continuous measurement mode). It is therefore advisable to place
the measuring tool at or on the measuring point.
The measurements are taken at the centre of the laser beam, even when the
laser is pointed at surfaces diagonally.
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 when
working outdoors and in bright sunlight, use the laser viewing glasses (15)
(accessory) and the laser target plate (16) (accessory) or shade the target
area.
Influences on the measurement result
Due to physical effects, the possibility of inaccurate measurements when
measuring various surfaces cannot be excluded.
These include:
- Transparent surfaces (e.g. glass, water)
- Reflective surfaces (e.g. polished metal, glass)
- Porous surfaces (e.g. insulating materials)
- Structured surfaces (e.g. roughcast, natural stone).
If necessary, use the laser target plate (16) (accessory) on these surfaces.
Layers of air at different temperatures and indirectly received reflections can also influ-ence the measured value.
Errors – causes and corrective measures
The measuring tool
monitors for correct operation in every measurement. If a defect is detected,
the display will show only the adjacent symbol. In this case, or when the
above-mentioned corrective measures cannot correct an error, have the
measuring tool checked by an after-sales service agent for Bosch power tools.
Accuracy check of the measuring tool
You can check the accuracy of the measuring tool as follows:
- Choose a measuring section of approx. 3–10 m in length that is permanently un-changed, the exact length of which is known to you (e.g. room width, door opening). The measuring section must be indoors, and the target surface of the measurement must be smooth and reflect well.
- Measure the section ten times in succession.
The deviation between the individual measurements and the mean value must not exceed ±2 mm. Record the measurements in order to be able to compare the accuracy later on.
Maintenance and Service
Maintenance and Cleaning
Only store and transport the measuring tool in the protective bag provided.
Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any detergents or
solvents.
Take particular care of the reception lens (12), which must be handled with
the same level of care you would give to a pair of glasses or a camera lens.
If the measuring tool needs to be repaired, send it off in the protective bag
(17).
