Scanning for “Live” Wires
The measuring tool indicates wires, which carry voltage between 110 V
and 240 V and a frequency corresponding to the widely used standard
(AC with 50 or 60 Hz). Other wires (carrying DC, higher/lower frequency
or voltage) as well as non-“live” wires/conductors cannot be found relia-
bly, but are possibly indicated as metal objects.
The detection for “live” wires/conductors takes place automatically with
every measurement. When a “live” wire/conductor is detected, the signal
LED 2 flashes red and an intermittent signal tone sounds with rapid tone
sequence. Move the measuring tool repeatedly over the surface to locate
the “live” wire/conductor more precisely. After moving over the surface
several times, the position of the “live” wire/conductor can be indicated
very accurately.
“Live” wires/conductors can be detected more easily when power con-
sumers (e.g. lamps, appliances) are connected to the wire being sought
and switched on.
Note: Always ensure that you hold the measuring tool firmly without
gloves to enable a good grounding. Also ensure that ladders/scaffolding
must be grounded. Avoid ladders/scaffolding whose supports have plas-
tic caps underneath them. Do not wear insulating footwear.
Under certain conditions (e.g. below metal surfaces or behind surfaces
with high water content), “live” wires/conductors cannot be securely de-
tected. When the signal LED 2 illuminates yellow or red over a larger area,
then the material is screening-off electrically and the detection for “live”
wires/conductors is not reliable.
Working Advice
Measuring values can be impaired through certain ambient condi-
tions. These include, e.g., the proximity of other equipment that
produce strong magnetic or electromagnetic fields, moisture, me-
tallic building materials, foil-laminated insulation materials or
conductive wallpaper or tiles. Therefore, please also observe other
information sources (e.g. construction plans) before drilling, sawing
or routing into walls, ceilings or floors.
Note: Do not hold the device in the area of the sensor, so as not to affect
the measurement. This achieves more accurate measurement results.
