A long battery runtime is achieved by means of energy-saving measures, such as deactivating the Bluetooth® function when not required, reducing the display brightness, etc.
The serial number (15) on the type plate is used to clearly identify your measuring tool.

A) For measurements from the front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a white-painted wall), weak backlighting and 25 °C operating temperature. In addition, a deviation of ±0.05 mm/m must be taken into account.

B) For measurements from the front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a white-painted wall), and strong backlighting. In addition, a deviation of ±0.15 mm/m must be taken into account.

C) After calibration at 0° and 90°. Additional pitch error of max. ±0.01°/degrees up to 45°. The measurement accuracy refers to the three orientations of the inclination measurement calibration, see figure H

D) At an operating temperature of 25 °C. Charging time with 1 A USB charger. Faster charging with the measuring tool switched off.

E) The left-hand side of the measuring tool serves as the reference level for grade measurement.

F) In continuous measurement mode, the max. operating temperature is +40 °C.

G) non-conductive soiling only, whereby occasional temporary conductivity caused by condensation is expected

H) The automatic switch-off time can be adjusted (to two, five, ten minutes or never).

1) When using Bluetooth® Low Energy devices, it may not be possible to establish a connection depending on the model and operating system. Bluetooth® tools must support the GATT profile.

Initial start-up

Charging the battery

▶ Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your measuring tool.
The use of chargers from other manufacturers can lead to defects on the measuring tool; a higher voltage (e.g. 12 V) from a vehicle charger is not suitable for charging this measuring tool. The warranty is rendered void if these instructions are not followed.

▶ Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the charger.

Note: The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery before the first use.

Note: The micro USB port (16) for connecting the micro USB cable (22) is located under the cover of the measuring pin (8). Press the release button (7) to open the cover.

The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery.

If the lower segment of the battery charge indicator (g) flashes, only a few more measurements can be made. Charge the battery.

If the frame around the segments of the battery charge indicator (g) flashes, no more measurements are possible. The measuring tool can only be used for a short time (e.g. to check entries in the measured value list). Charge the battery.

Connect the measuring tool to the charger (23) using the micro USB cable (22) provided. Plug the charger (23) into the socket. The charging process will begin.

The battery charge indicator (g) indicates the charging progress. The segments flash successively during charging. When all segments of the battery charge indicator (g) are displayed, the battery is fully charged.

If you are not planning to use the power tool again soon, disconnect the charger from the mains.

The battery can also be charged at a USB port. To do so, connect the measuring tool to a USB port using the micro USB cable. In USB mode (charging mode, data transfer), the charging time can be noticeably longer.

The measuring tool cannot be used on its own during the charging process.

Bluetooth® switches itself off during the charging process. Existing connections to other devices are interrupted. Data can be lost in the process.

Recommendations for optimal handling of the battery in the measuring tool

Only charge the measuring tool in the permissible temperature range, (see "Technical data", page 24). As an example, do not leave the measuring tool in a vehicle during the summer.

A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced by the Bosch after-sales service.

Follow the instructions on correct disposal.

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.

26 | English

▶ 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. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences Accuracy Check of the Measuring Tool.
The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed.

Changing the reference level (see "Selecting the reference level (see figure A)", page 26). 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) [▲] Then 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) [▲]

▶ 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", page 27).

Selecting the reference level (see figure A)

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 measuring from a table edge)
• The centre of the thread (17) (e.g. for tripod measurements)

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 button (13) [Func].

In continuous measurement mode, the measuring tool can be moved relative to the target, 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 mode: To switch on the laser beam, briefly press the measuring button (2)

Move the measuring tool until the required distance value is shown in the display below.

Briefly pressing the measuring button (2) [▲] will interrupt the continuous measurement. The current measured value will be shown at the bottom of the display. The maximum and minimum measured value appear above it. Pressing the measuring button (2) [▲] once

more will start the continuous measurement again. Continuous measurement automatically switches off after five minutes.

Area measurement

Select the area measurement mode □ Then measure the width and length and height 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 (see indicator element (j)).

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 cues are shown above it.

Volume measurement

Select the volume measurement mode □ Then measure the width, length and depth 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 (see display element (j)). The first measured value is shown at the top of the display. 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 figure B)

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 lines (h).

b) Double indirect height measurement (see figure C)

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 line (a). The measured values for distances 1 and 2 and angle α can be found in the measured value lines (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.

a) Indirect length measurement (see figure D)

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 line (a). The measured values for distance 1 and angle α can be found in the measured value lines (h).

d) Trapezium measurement (see figure E)

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 figure F)

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 L_1 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 L_2 of the second wall. The individual measured value displayed in the measured value line (h) is added to the length L_1 . 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 L_x , 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 figure G)

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 required length.

Begin the stake out function by pressing the measuring button (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 a level for the digital spirit level.

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.

Memory functions

The value or end result of each completed measurement is automatically saved.

Tip: When the camera is switched on, the photo is saved automatically, together with the measuring result. The following information is printed on the photo:

• Measuring result
  – Individual measurements (required to determine the measuring result)
• Measuring function used

- Reference

- Date and time

- Tilt angle (only with spirit level switched on).

If the photo is intended to be used for documentation purposes and transferred via micro USB cable, we recommend disabling the zoom function.

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

▶ 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.

USB port

Data transfer via USB port

Data can be transferred from the measuring tool to certain devices with a USB port (e.g. computer, notebook) via its micro USB connection.

Connect the measuring tool to your computer or notebook using the micro USB cable. The operating system on your computer or notebook will automatically recognise the measuring tool as a drive.

Note: When the measuring tool is connected to a computer or notebook via the micro USB cable, the Li-ion battery will charge. The charging time varies according to the charging current.

Practical advice

▶ Further information can be found on the Bosch product page.

The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed.

General advice

The reception lens (20), the laser beam output (18) and the camera (19) 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 vis-

ibility of the laser beam in strong extraneous light, use the integrated camera (19), 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 received reflections can also influence the measured value.

Checking accuracy and calibrating the grade measurement (see figure H)

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°.

In case of greater deviation, the measuring tool must be recalibrated. To do so, select an 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 10m 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 ±2 mm over the entire measuring section in favourable conditions. Record the measurements in order to be able to compare the accuracy later on.

32 | English

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 indicator in the display.

If the laser point is not inside the target indicator, you must recalibrate the target indicator.

To do so, select can the settings. Follow the directions on the display.

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 conventional 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).

Errors – Causes and Corrective Measures

Cause Corrective measures
Temperature warning flashes, measurement not possible

The measuring tool is outside the operating temperature of -10°C to +45°C (in the continuous measurement function, up to +40°C).

Wait until the measuring tool has reached operating temperature.

	Check the application on your mobile device.

Cause Corrective measures

Check whether Bluetooth® is activated on your measuring tool and mobile device.

Check whether your mobile device has been overloaded.

Reduce the distance between the measuring tool and your mobile device.

Where possible, ensure that there are no obstructions (e.g. reinforced concrete, metal doors) between the measuring tool and your mobile device. Keep the equipment away from any sources of electromagnetic interference (e.g. WiFi transmitters).

Data transfer via USB port not possible

Micro USB cable Check that the micro USB

cable has been inserted correctly and securely.

Check that the micro USB cable has not been damaged in any way.

The measuring tool monitors for correct operation in every measurement. If a defect is detected, the display will indicate only the symbol shown opposite. In this case, or if you are unable to rectify an error using the corrective

measures above, send the measuring tool to Bosch customer service via your dealer.

NZDYIKI DSTKASHEAI YRSHKI, YIMP BNZIN,

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated placeholder underscores where none should exist in the GT. Hence, the OCR result is inconsistent with the Ground Truth.
