Assembly

Battery Charging

• Do not use a different battery charger. The battery charger provided is matched to the lithium ion battery in- stalled in your measuring tool.
• Observe the mains voltage! The voltage of the power source must correspond with the data on the type plate of the battery charger.

Note:-
The battery is supplied partially charged. To ensure full battery capacity, completely charge the battery in the charger before using for the first time.
The lithium ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery.
When the bottom segment of the battery charge-control indicator g flashes, only a few more measurements can be carried out. Charge the battery.
When the frame around the segments of the battery charge- control indicator g flashes, measurements are no longer possible. Continued use of the measuring tool is only possible for a short period (e.g., for checking entries in the measured-value list, performing a calculation, etc.). Recharge the battery.
The charge procedure begins as soon as the mains plug of the battery charger is plugged into the socket outlet and the charge connector 23 is plugged into socket 15.
The battery charge-control indicator g indicates the charging progress. During the charging procedure, the segments flash one after the other. When all segments of battery charge-control indicator g are displayed, the battery is completely charged.
Disconnect the battery charger from the mains supply when not using it for longer periods.
Additionally, the battery can also be recharged via a USB port. For this, connect the measuring tool to a USB port using the micro USB cable. In USB operation (recharging, data trans- mission), the charging duration n can be significantly pro- longed.
The measuring tool cannot be used independently during the charging procedure. Usage is possible only in combination with a USB connection and the available software.
The Bluetooth® function switches off during the charging procedure. Existing connections to other devices are interrupt- ed. This can lead to data loss.

• Protect the battery charger against moisture!

Notes for Optimum Handling of the Battery in the Measuring Tool
Store the measuring tool only within the allowable tempera-ture range, see “Technical Data”. As an example, do not leave the measuring tool in a vehicle in summer.
A significantly reduced working period after charging indi-cates that the battery is used and must be replaced.
Observe the notes for disposal.

Operation

Initial Operation

• Do not leave the switched on measuring tool unattended and switch the measuring tool off after use. Other persons could be blinded by the laser beam.
• Protect the measuring tool against moisture and direct sun light.
• Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for long time. In case of large varia- tions in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in tempera- ture, the accuracy of the measuring tool can be impaired.
• Avoid heavy impact to or falling down of the measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out an accuracy check each time before continuing to work).

Switching On and Off

For switching on the measuring tool, the following possibilities are given

• Press the On/Off button 4 The measuring tool is switched on and is in length measurement The laser is not activated.
• Pressing the measuring button 2 Measuring tool and laser are switched on. The measuring tool is in length measurement mode. When the measuring tool is inserted in the measuring rail 27, the grade measurement function is activated
• 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.

To switch off the measuring tool, press the On/Off button 4 for a few seconds.
When no button on the measuring tool is pressed for approx. 5 minutes, the measuring tool automatically switches off to save the batteries/rechargeable batteries.
When the angle is not changed for approx. 5 minutes when in the Grade measurement operating mode, the measuring tool automatically switches off to save the batteries/re- chargeable batteries.
When switching off automatically, all stored values are retained.

Measuring Procedure

When the measuring tool is inserted in the measuring rail 27, it is always in the length measurement or grade measurement function after switching on by pressing the measuring button
Other measuring modes can be switched to by pressing the respective function/mode button.
After switching on, the rear edge of the measuring tool is pre- set as the reference level for the measurement. By pressing the reference level button 10, the reference level can be changed.
Place the measuring tool with the selected reference plane against the desired starting point of the measurement (e.g. a wall).
Briefly press the measuring button 2 to switch on the laser beam.

• 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.

Aim the laser beam at the target surface. Briefly press the measuring button 2 again to imitate the measurement.
When the laser beam is switched on permanently, the Typically, the measured value appears after 0.5 and latest after 4 seconds. The duration of the measurement depends on the distance, the light conditions and the reflection proper- ties of the target surface. The end of the measurement is indicated by a signal tone. The laser beam is switched off auto- metrically upon completion of the measurement.
When no measurement takes place approx. 20 seconds after collimating, the measuring tool automatically switches off to save the battery.

Selecting the Reference Level

For the measurement, you can select between four reference planes

• The rear edge of the measuring tool or the front edge of the 90° folded-out positioning pin 9 (e. when measuring on- ward from outer corners),
• The tip of the 180° folded-out positioning pin 9 (e.g. when measuring from a corner),
• The front measuring-tool edge (e.g. when measuring on- ward from a table edge),
• The Centre of thread 19 (e. for tripod measurements).

To select the reference level, press button 10 until the re- quested reference level is indicated on the display. Each time after switching on the measuring tool, the rear end of the measuring tool is preset as the reference level.
Subsequent changing of the reference level for measurements that have already been carried out (e.g. when indicating measuring values in the measured-value list) is not possible.

Basic Settings

To access the Basic settings menu, press and hold the basic settings button 8.
Briefly press the basic settings button 8 to select the individual menu items.
Press the minus button 5 or the plus button 11 to select the setting within the menu items.
To exit the Basic settings menu, press the measurement button 2.

With exception of the Permanent laser beam setting, all ba- sic settings are retained when switching off.

Continuous Laser Beam

• 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.

In this setting, the laser beam also remains switched on between measurements for measuring, it is only required to press the measuring button 2 once.

Measuring Functions

Simple Length Measurement

For length measurements, press button 12 until the length measurement indication appears on the display.
To switch the laser on and for measuring, briefly press the measuring button 2 once each time.
The measured value is displayed in the result line c.
For several subsequent length measurements, the last measured results are displayed in the measured-value lines a.

Area Measurement

For area/surface measurements, press button 12 until the indicator for area measurement appears on the display.
Afterwards, measure the length and the width, one after an- other, in the same manner as a length measurement. The laser beam remains switched on between both measurements.
Upon completion of the second measurement, the surface is automatically calculated and displayed in the result line c. The individual measured values are displayed in the measured-value lines a.

Volume Measurement

For volume measurements, press button 12 until the indicator for volume measurement appears on the display. Afterwards, measure the length, width and the height, one after another, in the same manner as for a length measurement. The laser beam remains switched on between all three measurements.
Upon completion of the third measurement, the volume is automatically calculated and displayed in the result line c. The individual measured values are displayed in the measured-value lines a.
Values above 1000000 m3 cannot be indicated; “ERROR” appears on the display. Divide the volume to be measured in-to individual measurements; their values can then be calculated separately and then summarized.
Continuous Measurement (Tracking) / Minimum/Maxi-mum Measurement
For continuous measurements, the measuring tool can be moved relative to the target, whereby the measuring value is updated approx. every 0.5 seconds. In this manner, as an ex-ample, you can move a certain distance away from a wall, while the actual distance can always be read.
For continuous measurements, press function mode button 8 until the indicator for continuous measurement appears on the display. To start the continuous measurement, press the measuring button 2.
The minimum measurement is used to determine the shortest distance from a fixed reference point. It is used, as an example, for determining plumb lines or horizontal partitions. The maximum measurement is used to determine the greatest distance from a fixed reference point. It is used, as an example, for determining diagonals.
The current measuring value is displayed in the result line c. The maximal (“max”) and the minimal (“min”) measuring value are displayed in the measured-value lines a. It is always overwritten, when the cur-rent length measurement value is less than the present minimal or larger than the present maximal value.
The previous minimal and maximal values are deleted by pressing the button for clearing the internal memory 4. Pressing the measuring button 2 ends the continuous
measurement. The last measured value is displayed in the result line c. Pressing the measuring button 2 again restarts a continuous measuring run.
Continuous measurement automatically switches off after 5 min. The last measured value remains indicated in the result line c.

Indirect Distance Measurement

Note: Indirect distance measurement is always less accurate than direct distance measurement. Depending on application, greater measuring errors are possible than with direct distance measurement. To improve the measuring accuracy, we recommend using a tripod (accessory).
The indirect distance measurement is used to measure distances that cannot be measured directly because an obstacle would obstruct the laser beam or no target surface is available as a reflector. This measuring procedure can only be used in vertical direction. Any deviation in horizontal direction leads to measuring errors.
The laser beam remains switched on between the individual measurements.
For indirect length measurements, three measuring modes are available. Each measuring mode can be used for deter-mining different distances.

1.  Indirect height measurement
   Press the function-mode button 8 until the indication for indirect height measurement 1 appears on the display.
   Pay attention that the measuring tool is positioned at the same height as the bottom measuring point. Now, tilt the measuring tool around the reference plane and measure distance “1” as for a length measurement
   Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line c. The measuring values for the distance “1” and the angle “α”are displayed in the measured-value lines a.
2.  Double indirect height measurement
   Press the function-mode button 8 until the indication for dou1ble indirect height measurement appears on the display
   Measure distances “1” and “2” in this sequence as for a length measurement.
   Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line c. The measuring values for the distances “1”, “2” and the angle “α” are displayed in the measured-value lines a.
   Pay attention that the reference plane of the measurement (e.g. the rear edge of the measuring tool) remains exactly at the same location for all individual measurements within a measuring sequence.
3.  Indirect length measurement
   Press the function-mode button 8 until the indication for indirect length measurement 1 appears on the display.
   Pay attention that the measuring tool is positioned at the same height as the sought measuring point. Now, tilt the measuring tool around the reference plane and measure distance “1” as for a length measurement.
   Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line c. The measuring values for the distance “1”and the angle “α” are displayed in the measured-value lines a.

Wall Surface Measurement

The wall surface measurement is used to determine the sum of several individual surfaces with a common height .In the example shown, the total surface of several walls that have the same room height A, but different lengths B, are to be determined.
For wall surface measurements, press the function-mode but-ton 8 until the indicator for wall surface measurement appears on the display.
Measure the room height A as for a length measurement. The measured value (“c s t”) is displayed in the top measured-value line a. The laser remains switched on.
Afterwards, measure length B1 of the first wall. The surface is automatically calculated and displayed in the result line c. The length measurement value is dis-played in the center measured-value line a. The laser remains switched on.
Now, measure length B2 of the second wall. The individually measured value displayed in the center measured-value line a is added to the length B1. The sum of both lengths (“sum”, displayed in the bottom measured-value line a) is multi-plied with the stored height A. The total surface value is displayed in the result line c.
In this manner, you can measure any number of further lengths BX, which are automatically added and multiplied with height A.
The condition for a correct area/surface calculation is that the first measured length (in the example the room height A) is identical for all partial surfaces.

Grade Measurement

After pressing the grade measurement button 3, the indication for grade measurement appears on the display . The backside of the measuring tool is used as the reference plane. By pressing the grade measurement button 3 again, the side surfaces of the measuring tool are used as reference plane and the display view is shown turned by 90°.
Press the measuring button 2 to lock the measuring value and accept it in the measured values memory. Pressing the measuring button 2 again continues the measurement.
When the indication flashes during the measuring procedure, then the measuring tool was tilted too much in lateral direction.
If the “digital vial” function is activated in the basic settings, the grade value is also displayed in the other measuring functions in line d of display 1.

Timer Function

The timer function is helpful, when, for example, movements of the measuring tool during measuring are to be prevented. To activate the timer function, press and hold button 6 until the indicator appears in the display.
The time period from the actuation until the measurement takes place is displayed in the measured-value line a. The time period can be adjusted between 1 s and 60 s by pressing the plus button 11 or the minus button 5.
The measurement takes place automatically after the set time period has elapsed. The timer function can also be used for distance measurements within other measuring modes (e.g. area/surface measurement). Adding and subtracting measuring results as well as continuous measurements are not possible.

List of the last Measuring Values

The measuring tool stores the last 50 measuring values and their calculations, and displays them in reverse order (last measured value first).
To recall the stored measurements, press button 7. The result of the last measurement is indicated on the display, along with the indicator for the measured-value list e and the memory location of the dis- played measurements.
When no further measurements are stored after pressing but- ton 7 again, the measuring tool switches back to the last measuring function. To exit the measured-value list, press one of the measuring-mode buttons.
To continuously save the currently displayed length measurement value as a constant, press and hold the measured-value list button 7 until CST is indicated on the display. A measured-value list entry cannot be subsequently saved as a constant.
To use a length measurement value in a measuring mode (e. g. area/surface measurement), press the measured-value list button 7, select the desired entry and confirm by pressing the result button 6.

Deleting Measured Values

Briefly pressing button 4 deletes the last individual measuring value determined in any measuring function. Briefly pressing the button repeatedly deletes the individual
measuring values in reverse order.
To delete the currently displayed measured-value list entry, briefly press button 4. To delete the complete measured-value list and the constant CST , press and hold the measured- value list button 7 and at the same time briefly press button 4. In wall surface measurement mode, briefly pressing button 4 the first time deletes the last individually measured value pressing the button a second time deletes all lengths B_X, and pressing the button a third time deletes the room height A.

Adding Measured Values

To add measured values, firstly carry out any measurement or select an entry from the measured-value list. Then press the plus button 11. For confirmation, + appears on the display. Then carry out a second measurement or select another entry from the measured-value list.
To call up the sum of both measurements, press the result button 6. The calculation is indicated in the measured-value lines a, and the sum in the result
line c.
After calculation of the sum, further measured values or measured-value list entries can be added to this result when pressing the plus button 11 prior to each measurement. Pressing the result button 6 ends the addition.
Notes on the addition

• Mixed length, area and volume values cannot be added to- For example, when a length and area value are added, ERROR briefly appears on the display after pressing the result button 6. Afterwards, the measuring tool switches back to the last active measuring mode.
• For each calculation, the result of one measurement is added (e.g. the volume value) for continuous measurements, this would be the displayed measured value in result line c. The addition of individual measured values from the measured-value lines a is not possible.

Subtracting Measured Values

To subtract measuring values, press minus button 5 For confirmation, is indicated on the display. The further procedure is analog to Adding Measured Values.

Data Transmission to other Devices

The measuring tool is equipped with a Bluetooth® module, which enables data transmission via radio technology to certain mobile terminals/devices with a Bluetooth® interface (e.g., smartphones, tablets).
For information on the necessary system requirements for a Bluetooth® connection, please refer to the Bosch website at www.bosch-pt.de.
For data transmission via Bluetooth®, time delays between mobile terminal/device and measuring tool may occur. This can be possible due to the distance between both devices or the object being measured.
Data transmission to certain other devices with USB interface is possible via the measuring tool s micro USB port (e.g. to computers, notebooks). In USB operation, the charging duration n can be significantly prolonged during data transmission.

• Activating the Bluetooth® Interface for Data Transmission to a Mobile Terminal/Device

To activate the Bluetooth® interface, press the measuring tool s Bluetooth® button 13. Make sure that the Bluetooth® interface on your mobile terminal/device is activated.
Special Bosch applications (apps) are available to extend the functional range of the mobile terminal/device and for simplification of the data processing. Depending on terminal/device, these can be downloaded at the respective app stores

After starting the Bosch application, the connection between the mobile terminal/device and the measuring tool is established. When several active measuring tools are found, select the appropriate measuring tool. When only one active measuring tool is found, the connection is automatically established.

Note: When establishing the connection between the measuring tool and the mobile terminal/device (e.g., smartphone, tablet) the first time (pairing), the measuring tool s PIN code may be requested. In this case, enter 0000. The connection status and the active connection are indicated on the display 1 (l).
When a connection cannot be established within 5 minutes after pressing the Bluetooth® button 13, the Bluetooth® feature automatically switches off to save the batteries/rechargeable batteries.
When operating the measuring tool in the measuring rail 27, data transmission is not possible.

Deactivating the Bluetooth® Interface

To activate the Bluetooth® interface, press the Bluetooth® button 13 or switch the measuring tool off.
When the Bluetooth® interface is deactivated or when the Bluetooth® connection is interrupted (e.g., because of too large distance or obstructions between the measuring tool and the mobile terminal/device as well as electromagnetic disturbances), Bluetooth® (l) is no longer indicated on the display.

Data Transmission via USB Interface

Connect the measuring tool to your computer or notebook with the micro USB cable. After starting the software on your computer or notebook, a connection is established to the measuring tool.
To download the current software and for further information, please refer to the Bosch website at www.bosch-pt.de.
Note: As soon as the measuring tool is connected to a computer or notebook via the micro USB cable, the lithium ion battery is charged. The charge duration varies depending on the charging current.
To recharge the measuring tool as quickly as possible, use the provided charger, see Battery Charging.

Working Advice

• The measuring tool is equipped with a radio interface. Local operating restrictions, e.g. in airplanes or hospitals, are to be observed.

General Information

The reception lens 17 and the laser beam outlet 18 must not be covered when taking a measurement.
The measuring tool must not be moved while taking a measurement (with the exception of the continuous measurement and grade measurement functions). Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.

Influence Effects on the Measuring Range

The measuring range depends upon the light conditions and the reflection properties of the target surface. For improved visibility of the laser beam when working outdoors and when the sunlight is intense, use the laser viewing glasses 30 (accessory) and the laser target plate 31 (accessory), or shade off the target surface.

Influence Effects on the Measuring Result

Due to physical effects, faulty measurements cannot be excluded when measuring on different surfaces. Included here are

• 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).

If required, use the laser target plate 31 (accessory) on these surfaces.
Furthermore, faulty measurements are also possible when sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly received reflections can affect the measured value.

Accuracy Check and Calibration of the Grade Measurement

Regularly check the accuracy of the grade measurement. This is done by carrying out a reversal measurement. For this, place the measuring tool on a table and measure the grade. Turn the measuring tool by 180 ° and measure the grade again. The difference of the indicated reading may not exceed by more than 0.3 ° (max.).
In case of greater deviation, the measuring tool must be recalibrated. For this, press and hold the grade measurement but- ton 3. Follow the directions on the display.
After severe temperature changes and impact, we recommend an accuracy check and, if required, to recalibrate the measuring tool. After a temperature change, the measuring tool must acclimate for a while before calibrating.

Accuracy Check of the Distance Measurement

The accuracy of the distance measurement can be checked as follows:

• Select a permanently unchangeable measuring section with a length of approx. 1 to 10 meters; 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 ±2 mm (max.). Log the measurements, so that you can compare their accuracy at a later point of time.

Working with the Tripod (Accessory)

The use of a tripod is particularly necessary for larger distances. Position the measuring tool with the 1/4″ thread 19 onto the quick-change plate of the tripod 29 or a commercially available camera tripod. Tighten the measuring tool with the locking screw of the quick-change plate. Set the corresponding reference level for measurement with a tripod by pushing button 10 (the reference level is the thread).

Working with the Measuring Rail

The measuring rail 27 can be used for a more accurate grade measurement result. Distance measurements are not possible with the measuring rail.
Place the measuring tool into the measuring rail 27 as shown and lock the measuring tool with locking lever 28. Press the measuring button 2 to activate the “Measuring rail” operating mode.
Regularly check the accuracy of the grade measurement by carrying out a reversal measurement or with the spirit levels of the measuring rail.
In case of greater deviation, the measuring tool must be recalibrated. For this, press and hold the grade measurement but-ton 3. Follow the directions on the display.
When operating the measuring tool in the measuring rail 27, data transmission is not possible.
To end the “Measuring rail” operating mode, switch the measuring tool off and remove it from the measuring rail.

Troubleshooting – Causes and Corrective Measures

The measuring tool monitors the correct function for each measurement. When a defect is determined, only the symbol shown aside flashes in the display. 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.
