• Three-phase wiring is possibly not de-
tected as “live” conductor.
• Wires that are not “live” may be detected
as metal objects or may not be detected.
This includes solid copper cables, however
stranded copper cables are not detectable.
• Static electricity can lead to inaccurate de-
tection of electrical wires, especially, over
a large range. It may help to put a hand on
the wall next to the detector and measure
again in order to help remove the static
electricity.
Detection values can be impaired through
certain ambient conditions. These include,
but are not limited to, the proximity of other
equipment that produces strong magnetic
or electromagnetic fields, moisture, metallic
building materials, foil-laminated insulation
materials or conductive wallpaper or tiles.
Therefore, please also consult other informa-
tion sources (e.g. construction plans) before
drilling, sawing or routing into walls, ceilings
or floors.
Before penetrating surface (such as with a
drill, router, saw or nail), always shut off the
electrical power, gas and water supplies.
Cutting, drilling, etc. into these items when
operational can result in personal injury.
Marking Objects
If required, detected objects can be marked.
Perform measurement as described. Once
you have found the boundaries or the center
of an object, mark the sought location at the
top marking aid 1 and the side marking aid
4. Connect both points with a vertical and
horizontal line. The object is located at the
intersection of the lines.
Working Advice
Temperature Control
Note: If the device is lifted off the wall, a signal
may be shown temporarily.
When the temperature control indicator e lights
up, the battery of the measuring tool is not
within the operating temperature range or was
subject to large variations in temperature.
Change the batteries or wait until it has once
again reached the operating temperature
range.
Warning Function
When the display 3 indicates f and g send
the measuring tool to an authorized customer
service agent. The measuring tool is no longer
functional.
