[. . . ] do not operate the measuring tool in explosive atmospheres , such as in the presence of flammable liquids , gases or dusts. Sparks can be created in the measuring tool which may ignite the dust or fumes. 1 On/Off and memory delete button 2 Button for selection of the reference level 3 Memory subtraction button "M­" 4 Memory add button "M+" 5 Area measurement button 6 Length measurement button 7 Display 8 Alignment aid 9 Measuring button 10 Volume measurement button 11 Memory retrieve button "M=" 12 Tracking (continuous measurement) button 13 Laser warning label 14 Latch of battery lid 15 Battery lid 16 Laser beam outlet 17 Reception lens 18 Serial number 19 Laser viewing glasses* 20 Laser target plate* 21 Protective pouch Display Elements a Measuring functions Length measurement Tracking (continuous measurement) Area measurement Volume measurement b Battery low indicator c Temperature warning d Measured value/result e Unit of measure f Measurement reference level g Laser switched on h Individual measured value (for length measurement: result) i Measured values stored Digital Laser Rangefinder Article number Measuring range Measuring accuracy (typically) Lowest indication unit Operating temperature Storage temperature Relative air humidity, max. Laser class Laser type Laser beam diameter (at 25 °C) and at 10 m distance, approx. [. . . ] With the reference level selected, place the measuring tool against the desired measuring line (e. 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 the tracking function, the measurement already starts upon first actuation of the measuring button 9. The duration of the measurement depends on the distance, the light conditions and the reflection properties of the target surface. The laser beam is switched off automatically upon completion of the measurement. 20 seconds after sighting, the laser beam is switched off automatically to save the batteries. 24 | English Selecting the Reference Level (see figures A­B) Two different reference levels are available for measuring: ­ The rear edge of the measuring tool (e. To change the reference level, press button 2 until the requested reference level is indicated on the display. Each time after switching on the measuring tool, the rear end of the measuring tool is preset as the reference level. Push the measuring button 9 once for sighting and once more to take the measurement. After taking the second measurement, the area/surface 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. 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. English | 25 Continuous Measurement (Tracking) (see figure C) The continuous measurement function (tracking) is used for the transferring of measurements, e. In continuous measurement mode, the measuring tool can be moved relative to the target, whereby the measured value is updated approx. As an example, the user can move from a wall to the required distance, while the actual distance can be read continuously. Move the measuring tool until the required distance value is indicated at the bottom of the display. The continuous measuring can also be ended by pushing the buttons 6, 5 or 10 which changes the measuring function. When switching off the measuring tool, the value in the memory is retained. Storing/Adding Measured Values Push the memory add button 4 in 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 the "+" behind it briefly flashes. [. . . ] Com Our customer consultants answer your questions concerning best buy, application and adjustment of products and accessories. Only for EC countries: Do not dispose of measuring tools into household waste!According the European Guideline 2002/96/EC for Waste Electrical and Electronic Equipment and its implementation into national right, measuring tools that are no longer usable must be collected separately and disposed of in an environmentally correct manner. Battery packs/batteries: Do not dispose of battery packs/batteries into household waste, fire or water. [. . . ]
