Place the measuring tool on the surface to be scanned
and move it sidewards. When the illuminated ring 1
continues to light up green and no signal tone sounds,
then no metal object is detectable in the structual ma-
terial below. When the measuring tool comes close to a
metal object, the amplitude in the measuring indicator
c increases. When the measuring tool is above a metal
object, the ring 1 turns red and a signal tone sounds.
When moving over a surface the first time, the position of the metal object
is indicated only approximately. When moving the measuring tool over the
metal object several times, the object is detected more and more precise-
ly. After moving over the surface above the metal object several times
(without lifting off the measuring tool from the surface), the position of
the metal object can be indicated accurately: When the illuminated ring 1
lights up red and the signal tone sounds, then the metal object is below
the centre of the sensor (below the marking hole 2).
Scanning for "Live" Wires
The measuring tool indicates "live" wires/conductors that carry voltages
between 110 V and 400 V, and a frequency corresponding with the com-
mon standard (AC with 50 to 60 Hz). Other wires/conductors (carrying
DC, higher/lower frequency or voltage) as well as "dead" wires/conduc-
tors cannot be found reliably, but are possibly indicated as metal objects.
The scan for "live" wires/conductors takes place automatically for each
measurement. When a "live" wire/connductor is detected, the indicator b
appears in the display. Move the measuring tool over the surface repeat-
edly in order to localise the "live" wire. After moving the measuring tool
over the surface several times, the position of the "live" wire/conductor
can be indicated quite precisely. If the measuring tool is very close to the
wire/conductor, then the illuminated ring 1 lights up red and the signal
tone sounds with rapid tone sequence.
"Live" wires/conductors can be detected easier when power consumers
(e.g., 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 de-
tected with certainty. When measuring indicator c is indicated over a larger
