SCANNING FOR “LIVE” WIRES
The measuring tool can indicate “live” wires/conductors with 50 or 60 Hz
of AC. Other wires/conductors can only be indicated 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 indi-
cator
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 illu-
minated ring
1
flashes red and the signal tone sounds with a rapid tone
sequence.
“Live” wires/conductors can be detected easier when power consum-
ers (e.g., lamps, appliances) are connected to the wire/conductor being
sought and switched on. Wires/conductors with 110V, 240V and 380V
(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. These ranges can be recognised in the metal detec-
tion function. 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 detect-
ing-metal function. However, stranded cables are not indicated (contrary
to solid copper conductors).
OPERATING INSTRUCTIONS
On condition of the principle, the measuring values can be impaired
through certain ambient conditions. These include, e.g., the proximity
of other equipment that produce strong magnetic or electromagnet-
ic fields, moisture, metallic building materials, foil-laminated insulation
materials or conductive wallpaper. Therefore, please also observe other
information sources (e.g. construction plans) before drilling, sawing or
routing into walls, ceilings or floors.
