Batteries 2 x 1.5 V LR03 (AAA)Digital laser measure GLM 500 Rechargeable batteries 2 x 1.2 V HR03 (AAA) 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 ad- dition, a deviation of ±0.05mm/m must be taken into account. B) For measurements from the rear edge of the measuring tool, applies to low reflectivity of the tar- get (e.g. a dark-painted wall), strong backlighting and –10 °C to +45 °C operating temperature. In addition, a deviation of ±0.15 mm/m must be taken into account. C) After user calibration at 0° and 90°; an additional pitch error of ±0.01° up to 45° (max.) must be taken into account. The left-hand side of the measuring tool serves as the reference level for in- clination measurement. D) At an operating temperature of 25 °C 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) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected. H) Except battery compartment The serial number (11) on the type plate is used to clearly identify your measuring tool. Assembly Inserting/changing the batteries It is recommended that you use alkaline manganese batteries to operate the measuring tool. With 1.2 V batteries fewer measurements may be possible than with 1.5 V batteries. Press the locking mechanism (10) to open the battery compartment cover (9) and re- move the battery compartment cover. Insert the batteries. When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment. When the empty battery symbol first appears on the display, approx. 100 measurements are still possible. When the battery symbol is empty and flashes red, no further measure- ments are possible. Replace the batteries. Always replace all the batteries at the same time. Only use batteries from the same man- ufacturer and which have the same capacity. u Take the batteries out of the measuring tool when you are not using it for a pro- longed period of time. The batteries can corrode and self-discharge during pro- longed storage.

Others may be dazzled by the laser beam. u Protect the measuring tool from moisture and direct sunlight. u 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 ambi- ent temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperat- ure. u 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 (see "Checking accuracy and calibrating the inclination measurement (see figuresE1–E2)", page39). Switching on/off – To switch on the measuring tool and the laser, briefly press the measuring button (2)

– To switch on the measuring tool without the laser, briefly press the on/off button (5)

u Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a 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 measuring tool off. Measuring process Once switched on, the measuring tool is in the length measurement function. For a differ- ent measuring function, press the [Func] button (7). Use the [+] button (3) or the [–] button (8) to select the required measuring function (see "Measuring functions", page33). Activate the measuring function with the [Func] button (7) or with the meas- uring button (2) [ ]. Once the measuring tool has been switched on, the rear edge of the measuring tool is se- lected as the reference level for measurement. To change the reference level (see "Se- lecting the reference level (see figureA)", page33).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 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 laser beam is switched off. For a further measurement, repeat this process. u 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 ap- proximately four seconds. The duration of the measurement depends on the distance, the lighting conditions and the reflective properties of the target surface. Upon comple- tion of the measurement, the laser beam is automatically switched off. Selecting the reference level (see figureA) You can choose between three different reference levels for the measurement: – The rear edge of the measuring tool (e.g. when placing against walls) – The front edge of the measuring tool (e.g. when measuring from a table edge) – The centre of the thread (13) (e.g. for tripod measurements) To select the reference level, press the button (4). Use the [+] button (3) or the [–] but- ton (8) or the button (4) to select the required reference level. The rear edge of the measuring tool is preset as the reference level every time the measuring tool is switched on. Basic settings menu To enter the basic settings menu (h), press and hold the [Func] button (7). Select the respective basic setting and choose your setting. To exit the basic settings menu, press the on/off button (5) [ ]. Display illumination The display illumination is continuously switched on. When no button is pressed, the dis- play illumination is dimmed after approx. 20 seconds to preserve the batteries. Measuring functions Measuring length Select the length measurement mode . To switch on the laser beam, briefly press the measuring button (2) [ ].

The measured value will be shown at the bottom of the display.

m7.620 Repeat the above steps for each subsequent measurement. The last measured value is at the bottom of the display, the penultimate meas- ured value is above it, and so on. Continuous measurement In continuous measurement mode, the measuring tool can be moved relative to the tar- get, during which the measured value will be updated approx. 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 desired distance is shown at the bottom of the display.

-64° Briefly pressing the measuring button (2) [ ] will interrupt the continu- ous measurement. The current measured value will be shown at the bot- tom of the display. Pressing the measuring button (2) [ ] once more will start the continuous measurement again. Continuous measurement automatically switches off after fiveminutes. Area measurement Select the area measurement mode . 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 automatically calculated and displayed. The end result is shown at the bottom of the display, while the individual measured values 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 measure- ment. The laser beam remains switched on between the three measurements. The dis- tance to be measured flashes in the indicator for volume measurement . 1474.8 m

m10.160 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 measur- ing function can be used for determining different distances. The indirect distance measurement is used to determine distances that cannot be meas- ured 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 em- ployed vertically. Any horizontal deviation will lead to measurement errors. Note: Indirect distance measurement is always less accurate than direct distance meas- urement. For application-related reasons, measuring errors can be greater than with dir- ect 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 figureB) 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).

45° m20.000 45.0° Once the measurement is complete, the result for the required distance X is displayed in the result line (e). The measured values for distance 1 and angle α can be found in the measured value rows (d). b) Double indirect height measurement (see figureC) 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.

-10° m10.154 45.0° m12.208 Once the measurement is complete, the result for the required distance X is displayed in the result row (e). The measured values for distances 1 and 2 and angle α can be found in the measured value rows (d). 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 indi- vidual measurements in a single measuring process. c) Indirect length measurement (see figureD) 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.

60° m20.000 60.0° Once the measurement is complete, the result for the required distance X is displayed in the result row (e). The measured values for distance 1 and angle α can be found in the measured value row (d). Grade 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 align- ment of an object (e.g. washing machine, refrigerator, etc.). When the inclination exceeds 3°, the ball in the display lights up red. 36.0° 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 inclination 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 20 values (measured values or end results) can be retrieved. Press the memory button (6) [ ].430.16 m

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 corres- ponding measuring function is shown on the left. Press the [+] button (3) to browse forwards through the saved values. Press the [–] button (8) to browse backwards through the saved val- ues. If there is no value available in the memory, 0.000 is shown at the bottom of the display and 0 at the top. The oldest value is located in position 1 in the memory, while the newest value is in posi- tion 20 (when 20 memory values are available). When a further value is saved, it is al- ways the oldest value in the memory that is deleted. Deleting the memory Press the memory button (6) [ ] to delete the contents of the memory. Then briefly press the on/off button (5) [ ] to delete the displayed measured value. To delete all values in the memory, press the button (4) and the on/off button (5) [ ] at the same time, then release the on/off button (5) [ ].
