The end result is shown at the bottom of the display, while the individual measured values are shown above it.Indirect Distance MeasurementSelect the indirect distance measurement .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 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.Note: Indirect distance measurement is always less accurate 2610049010 10-17 GLM400C.indd 28 11/3/17 1:09 PM
29than 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 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).09.06.201713:20:2345º 121´09˝¼45.086´01˝¼Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line a. The measuring values for the distance “1” and the angle “ ” are displayed in the measured-value lines h.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.09.06.201713:20:23º30º107´09˝⅜160´04˝184´09˝35.5Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line a.

Pay attention that the measurement of distance “3” starts exactly at the end point of distance “1” and that a right angle exists between distances “1” and “2” as well as between “1” and “3”.09.06.201713:20:2360º11´10˝⅝8´00˝¾15´11˝¾14´04˝½Upon completion of the last measurement, the result for the sought distance “E” is displayed in the result line a. The individual measured values are displayed in the measured-value lines h.Wall Area Measurement (see figure F)The wall area measurement is used to determine the sum of several individual surfaces with a common height.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 area 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.09.06.201713:20:230.0º8´02˝⅜41´02˝⅜12´09˝½103´00˝Then measure the length L1 of the first wall. The surface is automatically calculated and displayed in the result line a. The last length measured value is in the bottom measured-value line h. The laser remains switched on.2610049010 10-17 GLM400C.indd 30 11/3/17 1:09 PM
31Now 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 bottom measured-value line h) is multiplied by the saved height H. The total surface 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 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 3.2 ft (0,1m), the maximum adjustable length is 164 ft (50m).Select the stake out function .Set the desired length. Using button 13 [Func] select the corresponding digit/position and change the value with button 4 [+] or button 11 [–].Begin the stake out function by pressing the measuring button 2 [ ] and slowly move away from the starting point.0´08˝1´04˝10.5xThe 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 3.1´04˝1´04˝1xThe 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 a red label indicate the actual value if the reference value is outside the display.2610049010 10-17 GLM400C.indd 31 11/3/17 1:09 PM
32Gradient Measurement/Digital Spirit LevelSelect the inclination measurement/digital spirit level .The measuring tool automatically switches between two states.1° 2° 3°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 3° exceeds, the ball in the display lights red.88.0°Gradient 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 FunctionsThe value or end result of each completed measurement is automatically saved.Tip: You can save your measurement as a photo for reference.The following information is printed on the photo:– Measuring result– Measuring function used– Reference– Date and time– Tilt angle (only with spirit level switched on).Memory value displayA maximum of 50 values can be retrieved (measured values or photos with measured values.Select the memory function using soft key 12 [ ].09.06.201713:20:2330º76´01˝⁄4430´05˝45´08˝60´10˝⅝The number of the memory value is shown at the top of the display, the corresponding memory value is shown at the bottom and the corresponding measuring function is shown on the left.Press button 4 [+] to browse forwards through the saved values.2610049010 10-17 GLM400C.indd 32 11/3/17 1:09 PM

34Bluetooth® InterfaceData Transmission to other DevicesThe 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.comFurther information can be found on the Bosch product page.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.Activating the Bluetooth® Interface for Data Transmission to a Mobile Terminal/DeviceThe Bluetooth® interface is activated in the basic settings. To activate the Bluetooth® signal, press button 4 [+]. Ensure that the Bluetooth® interface is activated on your mobile end device.The special Bosch “Measuring Master” app is available to extend the range of functions of the mobile end device and to make data easier to process. You can download this from the store for your end device type.The connection between mobile terminal/device and 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.The connection status, as well as the active connection (f), are shown in the display 1 of the measuring tool.Deactivating the Bluetooth® InterfaceThe Bluetooth® connection is deactivated in the basic settings. To deactivate the Bluetooth® signal, press button 11 [–] or switch off the measuring tool.2610049010 10-17 GLM400C.indd 34 11/3/17 1:09 PM
35Working AdviceFurther information can be found on the Bosch product page.The measuring tool is equipped with a radio interface. Local operating restrictions, e.g. in airplanes or hospitals, are to be observed.General InformationThe reception lens 20, the laser beam output 18 and the digital viewfinder 19 must not be covered during measurement.The measuring tool must not be moved while taking a measurement. 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 RangeThe 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 digital viewfinder 19, the laser viewing glasses 26 (accessory) and the laser target plate 25 (accessory) or shade the target area.Influence Effects on the Measuring ResultDue 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 25 (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.2610049010 10-17 GLM400C.indd 35 11/3/17 1:09 PM
36Accuracy Check and Calibration of the Grade Measurement (see figure H)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 the event of larger deviations, you have to recalibrate the measuring tool. For this, select CAL. Follow the instructions 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 MeasurementThe accuracy of the measuring tool can be checked as follows:– Select a permanently unchangeable measuring section which is approx. 9.8 to 32 ft (3 to 10 m) long and which you know the exact length of (e.g. room width, door opening). The measurement should be performed under favorable 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 distance 10 times in succession.The deviation of the individual measurements from the average value must not exceed ±.07 in (±2 mm) over the entire measuring section in favorable conditions. Record the measurements in order to be able to compare the accuracy at a later date.2610049010 10-17 GLM400C.indd 36 11/3/17 1:09 PM
37Checking accuracy and calibrating the target indicator (crosshair)Check the accuracy of the alignment of the laser and target indicator on a regular basis.– Select a bright area at least 10 m away with as little illumination as possible 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.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 17 onto the quick-change plate of the tripod 27 or a commercially available camera tripod. Tighten the measuring tool with the locking screw of the quick-change plate.Set the reference level for measurements with a tripod in the basic settings or by pressing button 3 (thread reference level).2610049010 10-17 GLM400C.indd 37 11/3/17 1:09 PM
38TroubleshootingCause Corrective MeasureTemperature warning flashes, measurement not possibleMeasuring tool not within the temperature range between +14°F and 113°F ( –10°C and +45°C).Wait until the measuring tool has reached the operating temperature.“ERROR” indication in the displayAddition/Subtraction of measured values with different units of measure.Only add/subtract measured values with the same units of measure.The angle between the laser beam and the target is too acute.Enlarge the angle between the laser beam and the target.The target surface reflects too intensely (e.g. a mirror) or insufficiently (e.g. black fabric), or the ambient light is too bright.Work with the laser target plate 25 (accessory).The laser beam outlet 18, reception lens 20, and/or digital viewfinder 19 are misted up (e.g. due to a rapid temperature change).Wipe the laser beam outlet 18, the reception lens 20, and/or digital viewfinder 19 dry using a soft cloth.Calculated value is greater than 1 999 999 or smaller than –999 999in/in2/in3.Divide calculation into intermediate steps.“CAL” and “ERROR” indication in the displayThe calibration of the grade measurement was not carried out in the correct sequence or in the correct positions.Repeat the calibration according to the instructions on the display and in the operating instructions.2610049010 10-17 GLM400C.indd 38 11/3/17 1:09 PM
39The surfaces used for the calibration were not accurately aligned (horizontal or vertical).Repeat the calibration on a horizontal or vertical surface; if required, check the surface first with a level.The measuring tool was moved or tilted while pressing the button.Repeat the calibration and hold the measuring tool in place while pressing the button.Bluetooth® cannot be activatedThe battery is too low. Change the measuring tool’s battery.No Bluetooth® connectionFailure of the Bluetooth® connection Switch off and restart Bluetooth® on the measuring tool and the mobile device.Check the application on your mobile terminal/device.Check if Bluetooth® is activated on your measuring tool and mobile terminal/device.Check your mobile terminal/device for overload.Reduce the distance between measuring tool and your mobile terminal/device.Avoid obstructions (e.g., reinforced concrete, metal doors) between measuring tool and your mobile terminal/device. Observe clearance to electromagnetic disturbances (e.g., WLAN transmitters).2610049010 10-17 GLM400C.indd 39 11/3/17 1:09 PM
40Measuring result not plausibleThe target surface does not reflect correctly (e.g. water, glass).Cover off the target surface.Laser beam output 18, reception lens 20 or digital viewfinder 19 is covered.Keep the laser beam output 18, reception lens 20 and digital viewfinder 19 clear.Wrong reference level set. Select reference level that corresponds to measurement.Obstruction in path of laser beam. Laser point must be completely on target surface.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.2610049010 10-17 GLM400C.indd 40 11/3/17 1:09 PM
41Maintenance and ServiceKeep the measuring tool clean at all times. Do not immerse the measuring tool into water or other fluids.Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents.Take extra special care when cleaning the reception lens 20, the laser beam exit opening 18 and the viewfinder 19:Ensure that there is no lint on the reception lens, the laser beam exit opening and the digital viewfinder. Clean the reception lens, the laser beam exit opening and the viewfinder only with cleaning agents which are also suitable for camera lenses. Do not attempt to remove dirt from the reception lens, the laser beam exit opening and the viewfinder using pointed objects, and do not wipe over the reception lens, the laser beam exit opening and the viewfinder (risk of scratching).If the measuring tool should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an authorized after-sales service center for Bosch power tools. Do not open the measuring tool yourself.In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the measuring tool.ENVIRONMENT PROTECTIONRecycle raw materials and batteries instead of disposing of waste.
