[. . . ] Switching On and Off B Before switching the measuring tool on, make sure that the sensor area 9 is not moist. B If the measuring tool was subject to an extreme temperature change, allow it to adjust to the ambient temperature before switching on. When switching the measuring tool on with the wood-detection button 5 or with the metal-detection button 6, it will automatically be in the respective detection function. When switching the measuring tool on with the "on/off" button 7 or with the "ZOOM" button 4, it will be in the detection function last used. [. . . ] Move the measuring tool over the surface repeatedly to localise the wooden object more precisely. After moving over the same area several times, the wooden object can be indicated quite accurately: The illuminated ring 1 lights up red and a steady tone sounds as long as the measuring tool is over the wooden object. Caution: When having placed the measuring tool onto the surface to be scanned under which a wooden object is coincidentally located, and having moved it over the surface, the measuring indicator f, the arrow below the "Zoom" function indicator d and the illuminated ring 1 flash red. In this case, start the scan again by repositioning the measuring tool somewhat offset onto the structure and pressing the "ZOOM" button 4 again. When scanning for wooden objects, metal objects are sometimes also indicated as objects found at depths between 2050 mm. to distinguish between wooden and metal objects , switch to the detecting-metal function (see "Detecting Metal Objects"). When an object is indicated at the same location in this function, then it is clearly a metal object and not a wooden object. to continue searching for wooden objects , switch back to the detecting-wood function. Scanning for "Live" Wires The measuring tool indicates lines that carry a voltage between 110 V and 400 V with frequencies corresponding to the widespread standard (AC with 50 or 60 Hz). Other lines (DC, higher/lower frequency or voltage) are indicated only as metal objects. "Live" wires/conductors are indicated both during a metal scan as well as during a wood scan. when a "live" wire/conductor is detected , the indicator a appears in the display. Move the measuring tool over the surface repeatedly in order to localise the "live" wire/conductor more precisely. After moving the measuring tool over the surface several times, the "live" wire/conductor can be indicated quite precisely. If the measuring tool is very close to the wire/conductor (four or five bars in indicator a), the illuminated ring 1 flashes red and the signal tone sounds with a rapid tone sequence. "Live" wires/conductors can be detected easier when power consumers (e. , lamps, appliances) are connected to the wire/conductor being sought and switched on. Wires/conductors with 110 V, 230 V and 400 V (three-phase current) are detected with about the same scan capacity. Under certain conditions (such as when behind metal surfaces or behind surfaces with high water content), "live" wires/conductors cannot be detected with certainty. When a measuring value is indicated all over a larger range of the measuring indicator f, then the material is screening off electrically and the scan for "live" wires/conductors is not reliable. Wires that are not "live" can be found as metal objects with the detectingmetal function. However, stranded cables are not indicated (contrary to solid copper conductors). [. . . ] In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the measuring tool. Exploded views and information on spare parts can be found under: www. 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.
