[. . . ] Working safely with the measuring tool is possible only when the operating and safety information are read completely and the instructions contained therein are strictly followed. Never make warning labels on the measuring tool unrecognisable. Caution ­ The use of other operating or adjusting equipment or the application of other processing methods than those mentioned here, can lead to dangerous radiation exposure. The measuring tool is delivered with a warning label in German language (marked with the number 13 in the representation of the measuring tool on the graphic page). [. . . ] Upon selection of the measuring function and the reference level, all further steps are carried out by pushing the measuring button 9. 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. aim the laser beam at the target surface. Push the measuring button 9 again to initiate the measurement. 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 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. 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. When placing against a wall), ­ The front measuring-tool edge (e. When measuring onward from a table edge). 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. the measured value is indicated at the bottom in the display. Area Measurement For area measurements, push button 5. 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. The laser beam remains switched on between all three measurements. [. . . ] For improved visibility of the laser beam when working outdoors and when the sunlight is intense, use the laser viewing glasses 19 (accessory) and the laser target plate 20 (accessory), or shade off the target surface. English | 27 Influence Effects on the Measuring Result Due to physical effects, faulty measurements cannot be excluded when measuring on different surfaces. If required, use the laser target plate 20 (accessory) on these surfaces. Also, air layers with varying temperatures or indirectly received reflections can affect the measured value. [. . . ]
