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

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 2610050173 04-18 GLM400CL.indd 30 4/19/18 11:12 AM31 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 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).

86´01˝¼ Upon 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.

Upon completion of the measurement, the result for the sought distance “X” is displayed in the result line a. The measuring values for the distances “1”, “2” and the angle “ ” are displayed in the measured-value lines h. 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 measure distance “1” as for a length measurement. 2610050173 04-18 GLM400CL.indd 31 4/19/18 11:12 AM32

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.

0.0º 8´02˝⅜41´02˝⅜12´09˝½ 103´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. 2610050173 04-18 GLM400CL.indd 32 4/19/18 11:12 AM33 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 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 [–]. Beginthestakeoutfunctionbypressingthemeasuringbutton 2 [ ] and slowly move away from the starting point. 0´08˝ 1´04˝

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. 2610050173 04-18 GLM400CL.indd 33 4/19/18 11:12 AM34 Gradient Measurement/Digital Spirit Level Select 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 Functions The 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).

Interface Do not turn on laser remotely using the Bosch app without line of sight to the laser tool. The sudden bright laser beam may increase the risk of personal injury or property damage. Ensure there are no bystanders in the direct path of the laser beam before turning on the laser remotely. 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 websiteat www.bosch-pt.com Further 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/Device The Bluetooth

interface is activated in the basic settings. To activate 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 measuringtoolisestablishedaftertheBoschapplicationhas 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. 2610050173 04-18 GLM400CL.indd 36 4/19/18 11:12 AM37 Deactivating the Bluetooth

connection is deactivated in the basic settings. To deactivate the Bluetooth

signal, press button 11 [–] or switch off the measuring tool. USB port DataviaUSBInterfacecanbetransferredfromthemeasuring tool to certain devices with a USB port (e.g. computer, notebook)viaitsmicroUSBconnection. Connect the measuring tool to your computer or notebook using the micro USB cable. The operating system on your computer or notebook will automatically recognize the measuring tool as a drive. Note: As soon as the measuring tool is connected to a computerornotebookviathemicroUSBcable,thelithiumion battery is charged. The charge duration varies depending on the charging current. Working Advice Further 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 Information The reception lens 20, the laser beam output 19 and the camera 18 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 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 18, the laser viewing glasses 26 (accessory) and the laser target plate 25 (accessory) or shade the target area. 2610050173 04-18 GLM400CL.indd 37 4/19/18 11:12 AM38 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 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. Accuracy 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. 2610050173 04-18 GLM400CL.indd 38 4/19/18 11:12 AM39 Accuracy Check of the Distance Measurement The 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. Checking 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. To do so, select in the settings. Follow the instructions on the display. 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 (thread reference level). 2610050173 04-18 GLM400CL.indd 39 4/19/18 11:12 AM40 Troubleshooting Cause Corrective Measure Temperature warning flashes, measurement not possible Measuring 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 display Addition/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 19, reception lens 20, and/ or camera 18 are misted up (e.g. due to a rapid temperature change). Wipe the laser beam outlet 19, the reception lens 20, and/or camera 18 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 display The 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. 2610050173 04-18 GLM400CL.indd 40 4/19/18 11:12 AM41 Cause Corrective Measure The 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
