With 1.2-V-rechargeable batteries fewer measurements could be possible than with 1.5-V-batteries. To open the battery lid 9, press the latch 10 and remove the battery lid. Insert the bat- teries/rechargeable batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment. When the empty battery symbol appears on the display, then approx. 100 measure- ments are still possible. When the battery symbol is empty and flashes red, no further measurements are possible. Change the batteries or rechargeable batteries. Always replace all batteries/rechargeable batteries at the same time. Do not use dif- ferent brands or types of batteries/rechargeable batteries together. Remove the batteries/rechargeable batteries from the measuring tool when not using it for longer periods. When storing for longer periods, the batteries/re- chargeable batteries can corrode and self-discharge. Operation Initial Operation Do not leave the switched-on measuring tool unattended and switch the mea- suring 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 a long time. In case of large variations 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 temperature, the accuracy of the measuring tool can be impaired. Avoid heavy impact to or falling down of the measuring tool. After severe exte- rior effects to the measuring tool, it is recommended to carry out an accuracy check (see “Accuracy Check of the Distance Measurement”, page 43) each time before continuing to work.

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 and hold the On/Off button 5 []. The measured values and device settings in the memory are retained when you switch the tool off. Measuring Procedure Once switched on, the measuring tool is in the length measurement function. For a different measuring function, press the button 7 [Func]. Select the desired measur- ing function with the buttons 3 [+] or the button 8 [–] (see “Measuring Functions”, page 35). Activate the measuring function with button 7 [Func] or with the measur- ing button 2 []. After switching on, the rear edge of the measuring tool is preset as the reference level for the measurement. To change the reference level, see “Selecting the Reference Level”, page 34. Place the measuring tool against the desired starting point of the measurement (e.g. a wall). Note: If the measuring tool has been switched on using the On/Off button 5 [], briefly press the measuring button 2 [ ] to switch the laser on. To initiate the measurement, briefly press the measuring button 2 []. Then the la- ser beam is switched off. For a further measurement, repeat this process. 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. Note: The measured value typically appears within 0.5 s and no later than approx. 4 s. The duration of the measurement depends on the distance, the lighting condi- tions and the reflective properties of the target surface. Upon completion of the measurement the laser beam is automatically switched off. Selecting the Reference Level (see figure A) For the measurement, you can select between three different reference planes: – the rear measuring-tool edge (e.g. when measuring onward from a wall), – the front measuring-tool edge (e.g. when measuring onward from a table edge), – the centre of thread 13 (e.g. for tripod measurements). OBJ_BUCH-2450-004.book Page 34 Thursday, November 26, 2015 10:46 AMEnglish | 35 Bosch Power Tools 1 609 92A 1RR | (26.11.15) To select the reference level, press button 4. Use button 3 [+] or button 8 [–] or but- ton 4 to select the desired reference level. The rear edge of the measuring tool is pre- set as the reference level every time the measuring tool is switched on. “Basic Settings” To enter the “basic configurations” menu (i) press and hold the button 7 [Func]. Select the respective basic configuration and your setting. To exit the “basic configurations” menu, press the On/Off button 5 [ ] again. Display Illumination The display illumination is continuously switched on. When no button is pressed, the display illumination is dimmed after approx. 20 seconds to preserve the batteries/re- chargeable batteries. Measuring Functions Length Measurement Select the length measurement . To switch on the laser beam, briefly press the measuring button 2 []. To measure, briefly press the measuring button 2 [ ]. The measured value will be shown at the bottom of the display. Repeat the above-mentioned steps for each subsequent measurement. The last measured value is at the bottom of the display, the penultimate measured value is above it, and so on. Continuous Measurement (Tracking) For continuous measurements, the measuring tool can be moved relative to the tar- get, whereby the measuring value is updated approx. every 0.5 seconds. In this man- ner, as an example, you can move a certain distance away from a wall, while the actual distance can always be read. Select the continuous measurement . To switch on the laser beam, briefly press the measuring button 2 []. Move the measuring tool until the required distance value is indicated in the bottom of the display.

The current measured value will be shown at the bot- tom of the display. The maximum and minimum measured value appear above it. Pressing the measuring button 2 [ ] once more, restarts the continuous measurement. Continuous measurement automatically switches off after 5 mins. Area Measurement Select the area measurement . 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 au- tomatically calculated and displayed. The end result is shown at the bot- tom of the display, while the individual measured values are shown above it. Volume Measurement Select the volume measurement . Then measure the width, length and depth one after the other as with a length meas- urement. The laser beam remains switched on between the three measurements. The distance to be measured flashes in the indicator for volume measurement . 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 For indirect length measurements, three measuring modes are available. Each meas- uring mode can be used for determining different distances. 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 ver- tical direction. Any deviation in horizontal direction leads to measuring errors. Note: Indirect distance measurement is always less accurate than direct distance measurement. Depending on application, greater measuring errors are possible than

To improve the measuring accuracy, we recom- mend using 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 . 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 the distance “1” as for a length measurement (displayed as a red line). Upon completion of the measurement, the result for the sought dis- tance “X” is displayed in the result line e. The measuring values for the distance “1” and the angle “α” are displayed in the measured-value lines d. b) Double indirect height measurement (see figure C) The measuring tool can indirectly measure all distances, which lie in the vertical level of the measuring tool. Select the double indirect height measurement . Measure distances “1” and “2” in this sequence as for a length measurement. Upon completion of the measurement, the result for the sought dis- tance “X” is displayed in the result line e. The measuring values for the distances “1”, “2” and the angle “α” are displayed in the measured-val- ue lines d. 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. c) Indirect length measurement (see figure D) Select the indirect length measurement . 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 meas- ure distance “1” as for a length measurement. Upon completion of the measurement, the result for the sought dis- tance “X” is displayed in the result line e. The measuring values for the distance “1” and the angle “α” are displayed in the measured-value lines d.

In the illustrated example, the total area of several walls should be determined, which have the same ceiling height H, but different lengths L. Select the wall surface measurement . Measure the ceiling height H as with a length measurement. The measured value is displayed in the top measured-value line. The laser remains switched on. Then measure the length L

of the first wall. The surface is automatically calculated and displayed in the result line e. The last length measured value is in the bottom measured-value line d. The laser remains switched on. Now measure the length L

of the second wall.The individual measured value displayed in the measured-value line d is added to the length L

The sum of the two lengths (displayed in the middle measured-value line d) is multi- plied by the saved height H. The total surface value is displayed in the result line e. You can measure any number of lengths L

, 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 ex- ample the ceiling height H) is identical for all sub-areas. Stake out function (see figure F) 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, the maximum adjustable length is 50 m. Select the stake out function . Set the desired length. Using button 7 [Func] select the corresponding digit/position and change the value with button 3 [+] or button 8 [–]. 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: The continuous measuring enables you to set a measured value as a defined length by pressing the button 4.

The green arrows on either side of the display indicate the reaching of a length for marking purposes. Inclination 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 align- ment of an object (e.g. washing machine, refrigerator, etc.). When the inclination 3° exceeds, the ball in the display lights red. Inclination 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. Memory value display Maximum 30 values (measured values or end results) can be retrieved. Select the memory function . The number of the memory value is shown at the top of the display, the corresponding memory value is shown at the bottom and the corre- sponding measuring function is shown on the left. Press button 3 [+] to browse forwards through the saved values. Press button 8 [–] to browse backwards through the saved values. If there is no value available in the memory, “0.000” is shown at the bottom of the dis- play and “0” at the top. The oldest value is located in position 1 in the memory, while the newest value is in position 30 (when 30 memory values are available). When a further value is saved, the oldest value in the memory is always deleted. m0.5000.500m1x 1°2° 3° 36.0°
