Automatic switch-off after approx.. –Laser –Rangefinder (Without measurement) Weight according to EPTA-Procedure 01/2003 Protection class (excluding battery compartment) 20 s 5 min 6.35 oz (0.18 kg) IP 54 (dust and Splash water protected) -11- A) The working range increases depending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and with increased brightness of the laser point to the ambient light intensity (interior spaces, twilight). In unfavorable conditions (e.g. when measuring outdoors at intense sunlight), it may be necessary to use the target plate. B) In unfavorable conditions (e.g. at intense sunlight or an insufficiently reflecting surface), the maximum deviation is ±10 mm per 70m (±7/16 in per 230 ft). In favorable conditions, a deviation influence of ±0.05 mm/m (±1/64 in per 26 ft) must be taken into account. C) In the Min. /Max. measurement function, the maximum operating temperature is +40 °C (104 *F). D) Fewer measurements are possible when using 1.2 V rechargeable batteries as compared with 1.5 V batteries. Please observe the article number on the type plate of your measuring tool. The trade names of the individual measuring tools may vary. The measuring tool can be clearly identified with the serial number 20 on the type plate.
INITIAL OPERATION Protect the rangefinder against moisture and direct sun irradiation. Do not expose the rangefinder to extreme temperatures or variations in temperature. Switching On and Off To switch on the rangefinder, briefly press the On/Off button 14 or measuring button 10. When switching on the rangefinder, the laser beam is not switched on yet. To switch off the rangefinder, press and hold the On/Off/clear button 14for a few seconds. To save the batteries, the rangefinder switches off automatically after approx.. 5 minutes when no measurement is carried out. When a measured value has been stored, it is retained in automatic switch-off mode. -12- Inserting/Replacing the Battery Use only alkali-manganese or rechargeable batteries. Fewer measurements are possible when using 1.2 V rechargeable batteries as compared with 1.5 V batteries. To open the battery lid 19, press the latch 18 in the direction of the arrow and remove the battery lid. Insert the batteries provided. Pay attention to the correct polarity of the batteries according to the representation in the battery compartment. When the battery symbol appears in the display for the first time, then at least 100 measurements are still possible. The batteries must be replaced when the battery symbol flashes; taking measurements is no longer possible. Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity. Remove the batteries from the rangefinder when not using it for extended periods. When storing for extended periods, the batteries can corrode and discharge themselves. INSTALLING HAND STRAP Feed string loop on end of hand strap 24under hand strap mounting post 27and pull out on other side. Feed hand strap 24 through string loop end and pull tight.

-13- When switching on the rangefinder again, “M”is indicated in the display. Measuring Procedure The rangefinder offers a variety of different measuring modes that can be selected by pushing the corresponding mode button (see “Measuring Mode”). After switching on, the rangefinder is in the “length measurement mode”. Also, it is possible to select any of the four different reference points for the measurement by pushing the reference point button 1(see “Selecting the Reference Point”). After switching on, the rear edge of the rangefinder is preset as the reference point. Upon selection of the measuring mode and the reference point, all further steps are carried out by pushing the measuring button 10. With the reference level selected, place the rangefinder against the desired measuring line (e.g. a wall). Push the measuring button 10to 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. Push the measuring button 10again to initiate the measurement. In the continuous laser beam mode, the measurement already starts upon first actuation of the measuring button 10. The measured value appears after 0.5 to 4 seconds. The duration of the measurement depends on the distance, the light conditions and the reflection properties of the target surface. The end of the measurement is indicated by a signal tone. The laser beam is switched off automatically upon completion of the measurement. When no measurement has taken place approx.. 20 seconds after sighting, the laser beam is switched off automatically to save the batteries. Selecting the Reference Point (see figures B–E) For measuring, it is possible to select from four different reference points: the rear edge of the rangefinder (e.g., when placing the measuring rangefinder flush against a wall), the rear edge of the extension pin 15(e.g., for measurements out of corners). the front edge of the rangefinder (e.g., as when measuring from the edge of a table onward), the center of the 1/4” threaded hole 17(e.g., for measuring with the tripod). !WARNING
-14- To select the reference point, push button 1repeatedly until the required reference point is indicated in the display. Each time after switching on, the rear edge of the rangefinder is preset as the reference point. Changing the Unit of Measure The unit of measure can be changed any time for display of the measured values, even for already measured or calculated values. For display of the current length measurement values, the units of measure shown above are available. Area and volume values as well as stored measured values can only be displayed in “ft” or “m”. To change the unit of measure, push button 13until a new unit of measure is displayed. The unit-of-measure setting is retained when switching the rangefinder on or off. Continuous Laser Beam If required, the rangefinder can be set so that the laser beam stays on in between measurements. For this, Briefly push button 13. The indication “ LASER ” lights up continuously in the display. 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; to take measurement, it is only required to push the measuring button 10 once. To switch off the continuous laser beam, briefly push button 13 again or switch the rangefinder off. When switching on again, the rangefinder is in the normal operation; the laser beam only appears when pushing the measuring button 10. MEASURING MODES Length Measurement For length measurements, push button 5until the indicator for length measurement appears in the display. Press the measuring button 10 once for sighting and once more to take the measurement. The measured value is indicated at the bottom in the display. !WARNING
-15- Area Measurement For area measurements, push button 5until the indicator for area measurement appears in the display. Afterwards, measure the length and the width, one after another, in the same manner as a length measurement. The laser beam remains switched on between both measurements. After taking the second measurement, the area is automatically calculated and displayed. The last individual measured value is indicated at the bottom in the display, while the final result is shown at the top. Volume Measurement For volume measurements, push button 5until the indicator for volume measurement appears in 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. After taking the third measurement, the volume is automatically calculated and displayed. The last individual measured value is indicated at the bottom in the display, while the final result is shown at the top. Values above 999990 ft 3 cannot be displayed; “Error”and “- - - -” appear on the display. In this case, switch the unit of measure to meters (see “Changing the Unit of Measure”, page 14). Area or Volume Rounding of Large Calculations For values larger than 9999 feet or meters the rangefinder rounds the calculated value to the nearest 10 feet or 10 meters. Accuracy in such situations is always 99.95% or better. Minimum Measurement (see figure F) 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. For minimum measurements, press button 4 until “MIN” appears in the display.
-16- To start the measurement, briefly push the measuring button 10. Move the laser back and forth over the requested target (e.g., the room ceiling for determining the plumb line) in such a manner that the reference point of the measurement (e.g., the tip of the extension pin 15) always remains at the same location. During the measurement, the current length measurement value is indicated at the bottom of the display. The minimum value is indicated at the top right in the display. It is always overwritten, when the current length measurement value is lower than the present minimal value. To end the minimum measurement, briefly push the measuring button 10. Pushing the measuring button again starts a new measurement. Maximum Measurement (see figure G) The maximum measurement is used to determine the greatest distance from a fixed reference point. It is used, as an example, for determining diagonals. For maximum measurements, push button 4until “MAX” appears in the display. To start the measurement, briefly push the measuring button 10. Move the laser back and forth over the requested target (e.g., the room corner for determining the diagonal) in such a manner that the reference point of the measurement (e.g., the tip of the extension pin 15) always remains at the same location. During the measurement, the current length measurement value is indicated at the bottom of the display.The minimum value is indicated at the top right in the display. It is always overwritten, when the current length measurement value is larger than the present maximal value. To end the maximum measurement, briefly push the measuring button 10. Pushing the measuring button again starts a new measurement. Indirect Length Measurement (see figure H) The indirect length measurement is used to measure distances that cannot be measured directly because an obstacle would obstruct the laser beam or no
-17- target surface is available as a reflector. Correct results are achieved only when the laser beam and the sought distance form an exact right angle (90°) (Pythagorean Theorem). In the illustrated example, the length Bis to be determined. For this purpose, Aand Cmust be measured. Aand Bmust form a right angle. For indirect length measurements, push button 11 until the indicator for indirect length measurement appears in the display. Measure the distance Aas for a length measurement. Pay attention that the line segment A and the sought distance Bform a right angle. Afterwards, measure the distance C. The laser beam remains switched on between both measurements. Pay attention that the reference point of the measurement (e.g., the rear edge of the rangefinder) is at the exact same location for both measurements. After completing the second measurement, the distance Bis calculated automatically.The last individual measured value is indicated at the bottom in the display, while the final result Bis indicated at the top in decimal feet or meters. Multi-Surface Area Measurement (see figure I) The multi-surface area measurement is used to determine the sum of several individual surfaces with a common length. 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 multi-surface area measurements, push button 11 until appears in the display. Measure the room height Aas for a length measurement. The measured value is indicated both at the top and bottom in the display. The laser remains switched on. Afterwards, measure length B 1 of the first wall. The surface is automatically calculated and indicated. The last length measurement value is indicated
-18- at the bottom in the display, while the surface is indicated at the top. The laser remains switched on. Now, measure length B 2 of the second wall. The individual measuring value indicated at the bottom of the display is added to length B 1 and the sum of both lengths is multiplied with the stored length A. The total surface value is indicated at the top in the display. In this manner, you can measure any number of further lengthsB X, which are added and multiplied with length 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. To restart the multi-surface area measurement, push button 11twice. Continuous Measurement (Tracking)(see figure J) Use Min. / Max. measurement mode for continuous measurement function (tracking). The continuous measurement function (tracking) is used for the transferring of measurements, e.g., from construction plans. In continuous measurement mode, the rangefinder can be moved relative to the target, whereby the measured value is updated approx.. every 0.5 seconds. As an example, the user can move from a wall to the required distance, while the actual distance can be read continuously. For continuous measurements, select the Min. or Max. measuring function. Move the rangefinder until the required distance value is indicated at the bottom of the display. Pushing the measurement button 10 interrupts the continuous measurement.The current measured value is indicated in the bottom of display. Repeated pushing of the measuring button 10starts the measuring again. The measuring automatically switches off after 5 minutes. The last measured value remains indicated in the display. The measuring can also be ended by pushing button 5 or 11, which changes the measuring mode. Deleting Measured Values Pushing on clear button 14 deletes the last individual measuring value determined in
-19- all measuring functions. Pushing the button repeatedly deletes the individual measured values in reverse order. In the multi-surface area measurement mode, pushing button 14the first time deletes the last individually measured value; pushing the button a second time deletes all lengths B X. Memory Modes When switching off the Rangefinder, the value in the memory is retained. In the multi-surface area measur- ement mode, the total surface value can be stored; in the minimum and maximum measuring mode, the minimum and maximum value can be stored correspondingly. Storing individual measuring values within these functions is not possible. Storing/Adding Measured Values Push the memory add button 3in order to store the current measured value – a length, area or volume value, depending on the current measuring function. As soon as a value has been stored, “M” is indicated in the display and “add”is briefly indicated next to it. If a value is already stored in the memory, the new value is added to the memory contents, however, only if it’s the same type of measurement. As an example, when an area value is in the memory and the current measured value is a volume value, the addition cannot take place. “Error”briefly flashes in the display. However, values of the same type (e.g. length values) can be added no matter if they have been measured in feet and inches, decimal feet or meters. Subtracting Measured Values Push the memory subtraction button 12in order to subtract the current measured value from the memory value. As soon as a value has been subtracted, “M” is indicated in the display and is briefly followed by “SUB”. If a value is already stored in the memory, the new measured value can be subtracted only when the measures of unit correspond (see “Storing/Adding Measured Values”).
-20- Displaying the Stored Value Push the memory retrieve button 2in order to display the value stored in the memory. “M=”is indicated in the display. When the memory contents “M=”is indicated in the display, it can be doubled by pushing the memory add button 3or set to zero by pushing the memory subtract button 12. The memorized values can only be displayed in decimal feet or meters. Deleting the Memory To delete the memory contents, first push the memory retrieve button 2, so that “M=”is indicated in the display. Then push the clear button 14; “M” is no longer indicated in the display. The reception lens 22and the laser beam outlet 21must not be covered when taking a measurement. The rangefinder must not be moved while taking a measurement (with the exception of the continuous measurement mode). Therefore, whenever possible, place the rangefinder against or on the measuring points. Measurement takes place at the center of the laser beam, even when target surfaces are sighted at an incline. 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 25and the laser target plate 26, or shade off the target surface. When measuring against transparent surfaces (e.g. glass, water) or reflecting surfaces, faulty measurements are possible. Also, porous or structured surfaces, air layers Operating Instructions
