When moving over a metal object the first time, its po-

sition is only indicated coarsely. When moving the

measuring tool over the metal object several times, the

object is detected more and more precise. After mov-

ing over the metal object several times (without lifting

the measuring tool from the surface), the position of

the metal object can be indicated accurately: When the

signal LED 2 lights up red and the audio signal sounds,

the metal object is below the centre of the sensor.

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” conductors takes place automatically with each meas-

urement. When a “live” conductor is detected, indicator b appears on the

display. Move the measuring tool repeatedly over the area to localise the

“live” conductor more precisely. After moving over the “live” conductor

several times, its position can be indicated very accurately. When the

measuring tool is very close to the conductor, the signal LED 2 flashes red

and the audio signal beeps swiftly.

“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 larg-

er range, then the material is screening-off electrically and the scan for

“live” wires/conductors is not reliable.

Working Advice

f 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.
