using the rotary lock. Insert the batteries. When inserting
the batteries, ensure that the polarity is correct according
to the illustration on the inside of the battery compartment.
u 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.
u Note: TrackMyTools can only be used when batteries are
inserted.
Operation
Start-Up
u 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.
u Protect the measuring tool from moisture and direct
sunlight.
u Do not expose the measuring tool to any extreme tem-
peratures 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.
u Avoid substantial knocks to the measuring tool and
avoid dropping it. 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 distance measurement", page18).
u The measuring tool is equipped with a wireless inter-
face. Local operating restrictions, e.g. in aeroplanes
or hospitals, must be observed.
Switching On/Off

Measuring process
Once switched on, the measuring tool is in the length measurement function. For a different measuring function, press
the [Func] button (13). Use the [+] button (4) or the [–]
button (11) to select the required measuring function (see
"Measuring functions", page14). Activate the measuring
function with the [Func] button (13) or with the measuring
button (2) [ ].
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 (see "Selecting the reference level (see figureA)", page13). Apply
the measuring tool to the point at which you want to start the
measurement (e.g. wall).
Note: If the measuring tool has been switched on using the
on/off/delete button (9) [ ], briefly press the measuring
button (2) [ ] to switch the laser on.
To initiate the measurement, briefly press the measuring
button (2) [ ]. Afterwards, the laser beam is switched off.
For a further measurement, repeat this process.
With the laser beam continuously switched on and when in
the continuous measurement function, the measurement begins the first time you press the measuring button (2) [ ].
u Do not direct the laser beam at persons or animals and
do not stare into the laser beam yourself (even from a
distance).
Note: The measured value typically appears within half a
second, and no later than approximately four seconds. 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 is automatically switched off. The continuously
switched-on laser beam is not switched off after the measurement (see "Continuous laser beam", page13).
Selecting the reference level (see figureA)
You can choose between four different reference levels for
the measurement:
– The rear edge of the measuring tool (e.g. when placing
against walls)
– The tip of the measuring pin (8) folded by 180° (e.g.
when measuring from a corner)
– The front edge of the measuring tool (e.g. when measur-
ing from a table edge)
– The centre of the thread (17) (e.g. for tripod measure-
ments)
The folding out and in of the measuring pin (8) by 180° is detected automatically and the appropriate reference level is
suggested. Confirm the setting by pressing the measuring
button (2) [ ].
Select the settings for the measuring tool using the [ ] soft
key (3). Use the [+] button (4) or the [–] button (11) to select the reference level and confirm this by pressing the
[Func] button (13).
The rear edge of the measuring tool is automatically preset
as the reference level every time the measuring tool is
switched on.
Continuous laser beam
If necessary, you can switch the measuring tool to continuous laser beam operation. To do this, select the settings for
the measuring tool using the soft key (3) [ ]. Use the button (4) [+] or the button (11) [–] to select the continuous
laser beam and confirm this by pressing the button (13)
[Func].
u Do not direct the laser beam at persons or animals and
do not stare into the laser beam yourself (even from a
distance).
In this setting, the laser beam remains switched on even
between measurements; measurement simply requires one
brief press of the measuring button (2) [ ].
The continuous laser beam can be switched off again in the
settings or automatically when the measuring tool is
switched off.

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.
Indirect distance measurement
Select the indirect distance measurement mode . There
are four measuring functions available for the indirect distance measurement, each of which is capable of determining
different distances.
The indirect distance measurement is used to determine distances that cannot be measured directly, due to an obstacle
that would impede the path beam or the absence of a target
surface that could serve as a reflector. This measuring procedure can only be employed vertically. Any horizontal deviation will lead to measurement errors.
Note: Indirect distance measurement is always less accurate
than direct distance measurement. For application-related
reasons, measuring errors can be greater than with direct
distance measurement. To improve the accuracy of measurement, we recommend the use of a tripod (accessory).
The laser beam remains switched on between the individual
measurements
a) Indirect height measurement (see figureB)
Select the indirect height measurement mode .
Ensure that the measuring tool is at the same height as the
lower measuring point. Then tilt the measuring tool around
the reference level and measure distance 1 as for a length
measurement (displayed as a red line).
Once the measurement is complete, the result
for the required distance X is displayed in the
result line (a). The measured values for distance 1 and angle α can be found in the measured value rows (h).
b) Double indirect height measurement (see figureC)
The measuring tool can indirectly measure all distances that
lie in the vertical level of the measuring tool. Select the
double indirect height measurement mode . Measure distances 1 and 2 in succession as for a length measurement.
Once the measurement is complete, the result
for the required distance X is displayed in the
result row (a). The measured values for distances 1 and 2 and angle α can be found in the
measured value rows (h).
Ensure that the reference level for the measurement (e.g. the rear edge of the measuring tool) remains
in exactly the same place for all the individual measurements
in a single measuring process.
c) Indirect length measurement (see figureD)
Select the indirect length measurement mode .
Ensure that the measuring tool is at the same height as the
required measuring point. Then tilt the measuring tool
around the reference level and measure distance 1 as for a
length measurement.
Once the measurement is complete, the result
for the required distance X is displayed in the
result row (a). The measured values for dis-
tance 1 and angle α can be found in the meas-
ured value row (h).
d) Trapezium measurement (see figureE)
The trapezium measurement can be used to determine the
length of a roof slope, for example.
Select the trapezium measurement .
Measure distances 1, 2 and 3 in succession as for a length
measurement. Ensure that the measurement of distance 3
begins exactly at the point where distance 1 ends and that
distances 2 and 3 are at right angles to distance 1.

Once the final measurement is complete, the
result for the required distance X is displayed
in the result line (a). The individual measured
values can be found in the measured value
lines (h).
Wall area measurement (see figureF)
The wall area measurement is used to determine the sum of
multiple individual areas with a common height. In the illustrated example, the total area of several walls that have the
same ceiling height H but different lengths L is to be determined.
Select the wall area measurement mode .
Measure the ceiling height H as for a length measurement.
The measured value is displayed in the top measured-value
line. The laser remains switched on.
Then measure the length L1 of the first wall.
The area is automatically calculated and displayed in the result line (a). The last measured
value for length can be found in the bottom
measured value line.(h). The laser remains
switched on.
Now measure the length L2 of the second wall. The individual
measured value displayed in the measured value line (h) is
added to the length L1. The sum of the two lengths (displayed in the middle measured value line (h)) is multiplied
by the saved height H. The total area value is displayed in the
result line (a).
You can measure any number of lengths Lx, which will be
automatically added and multiplied by the height H. The requirement for a correct area calculation is that the first
measured length (for example the ceiling height H) is
identical for all sub-areas.
Stake out function (see figureG)
The stake out function repeatedly measures a defined length
(distance). These lengths can be transferred to a surface, for
example to enable material to be cut into pieces of equal
lengths or to install stud walls in a drywall construction. The
minimum adjustable length is 0.1 m and the maximum
length is 50 m.
Note: The distance from the marking is shown in the display
in the stake out function. The reference is not the edge of
the measuring tool.
Select the stake out function .
Use the button (4) [+] or the button (11) [–] to set the re-
quired length.
Begin the stake out function by pressing the measuring but-
ton (2) [ ] and slowly move away from the starting point.
The measuring tool continuously measures the
distance to the starting point. The defined
length and the current measured value are
thereby displayed. The lower or upper arrow
displays the shortest distance to the next or
last marking.
Note: When measuring continuously, you can set a measured value as a defined length by pressing the measuring
button (2) [ ].
The left factor specifies how many times the
defined length has already been reached. The
green arrows on either side of the display indicate the reaching of a length for marking purposes.
Red arrows or red text indicate the actual value when the reference is outside of the display.
Grade measurement/digital spirit level
Select the inclination measurement/digital spirit level .
The measuring tool automatically switches between two
states.
The digital spirit level is used to check the horizontal or vertical alignment of an object (e.g.
washing machine, refrigerator, etc.).
When the inclination exceeds 3°, the ball in the
display lights up red.
The bottom of the measuring tool is used as
the reference level for the digital spirit level.
Grade measurement is used to measure a
slope or incline (e.g. of stairs, railings, when
fitting furniture, laying pipes, etc.).
The left-hand side of the measuring tool serves
as the reference level for grade measurement.
If the display flashes during measurement, the
measuring tool has been tipped too heavily to the side.

Bluetooth® interface
Transmitting data to other devices
The measuring tool is fitted with a Bluetooth® module which
enables wireless data transfer to certain mobile devices with
a Bluetooth® interface (e.g. smartphone, tablet).
Information about the system requirements for a Bluetooth®
connection can be found on the Bosch website at
www.bosch‑pt.com
u Further information can be found on the Bosch
product page.
When transmitting data by means of Bluetooth®, time lags
may occur between the mobile device and the measuring
tool. This can be due to the distance between the two
devices or the measurement object itself.
Activating the Bluetooth® interface for transmitting data
to a mobile device
The Bluetooth® interface is activated in the settings. To activate the Bluetooth® signal, press the button (4) [+]. Ensure
that the Bluetooth® interface is activated on your mobile
device.
The Bosch Measuring Master app is specially designed to extend the range of functions of the mobile device and make
data easier to process. This can be downloaded from the respective store of the device.
The connection between the mobile device and the measuring tool is established after the Bosch application has started. If multiple active measuring tools are found, select the
appropriate measuring tool using the serial number. You can
find the serial number (15) on your measuring tool's type
plate.
The connection status, as well as the active connection (f),
are shown in the display (1) of the measuring tool.
Deactivating the Bluetooth® interface
The Bluetooth® connection is deactivated in the settings. To
deactivate the Bluetooth® signal, press the button (11) [–]
or switch off the measuring tool.
Practical advice
u Further information can be found on the Bosch
product page.
u The measuring tool is equipped with a wireless inter-
face. Local operating restrictions, e.g. in aeroplanes
or hospitals, must be observed.
General advice
The reception lens (18), the laser beam output (19) and the
camera (20) must not be covered during measurement.
The measuring tool must not be moved while a measurement
is being taken. For this reason, place the measuring tool
against or on a firm surface whenever possible.
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 strong extraneous light, use the integrated camera (20), the laser viewing glasses (26) (accessory) and the laser target plate (25) (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 (25) (accessory) on
these surfaces.
Inaccurate measurements are also possible where the laser
is pointed at target surfaces diagonally.
Layers of air at different temperatures and indirectly re-
ceived reflections can also influence the measured value.
Checking accuracy and calibrating the grade
measurement (see figureH)
Regularly check the accuracy of the grade measurement.
This is accomplished by means of a reverse measurement.
To do this, lay the measuring tool on a table and measure the
inclination. Turn the measuring tool by 180° and measure
the inclination again. The difference between the displayed
values must not exceed 0.3°.
Bosch Power Tools1 609 92A 62J | (22.09.2020)
18 | English
In case of greater deviation, the measuring tool must be recalibrated. To do so, select in the settings. Follow the
directions on the display.
We recommend that you perform an accuracy check and if
necessary a calibration of the measuring tool after extreme
temperature variations and after impact to the tool. After a
temperature variation, the measuring tool must acclimatise
for a while before calibration is performed.
Accuracy check of the distance measurement
You can check the accuracy of the measuring tool as follows:
– Choose a measuring section of approx. 3 to 10 m in
length that is permanently unchanged, the exact length of
which is known to you (e.g. room width, door opening).
The measurement should be performed under favourable
conditions, i.e. the measuring section should be indoors
with weak backlighting and the target area of the measurement should be smooth and reflect well (e.g. a white-
painted wall).
– Measure the section ten times in succession.
The deviation of the individual measurements from the mean
value must not exceed ±2mm over the entire measuring section in favourable conditions. Record the measurements in
order to be able to compare the accuracy later on.
Checking accuracy and calibrating the target
indicator (crosshairs)
Check the accuracy of the alignment of the laser and target
indicator on a regular basis.
– Select a bright area at least five metres away with as little
illumination as possible (e.g. a white wall) as the target.
– Check whether the laser point is inside the target indic-
ator in the display.
If the laser point is not inside the target indicator, you must
recalibrate the target indicator.
To do so, select in the settings. Follow the directions on
the display.
For longer distances (of approx. more than five metres), a
target marker is also superimposed to mark the measuring
point.
Working with the tripod (accessory)
The use of a tripod is particularly necessary for larger distances. Place the measuring tool with the 1/4" thread (17)
on the quick-release plate of the tripod (27) or a commercially available camera tripod. Tighten it using the locking
screw of the quick-release plate.
Set the reference level for measurements with a tripod in the
settings (tripod reference level).
