Information on material identification:
– For live objects, no further characteristic is
displayed.
– At a relative humidity above 50 %, detecting
the "live" property may be limited.
Power Cable
When a live conductor is detected: color of the
object
in display is yellow, no further
characteristic is displayed.
Note: “Live” conductors can be detected
easier when power consumers (e.g. lamps,
machines) are connected to the sought
conductor and switched on.
“Live” Wire Detection
Read all instructions. Failure to follow all
instructions listed below may result in property
damage, electric shock, fire and/or serious
injury.
Under certain conditions (such as when behind
metalized or conductive surfaces, shielded in
metal conduit or behind surfaces with high
water
content/moisture), “live” wires/
conductors cannot be detected with certainty.
These ranges may be recognized as metal
objects.
The signal strength of a “live”
wire/conductor depends on the position of the
cable. Therefore, apply further measurements in
close proximity or use other information sources
to check if a “live” wire/conductor exists.
• Three-phase wiring is possibly not detected 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
detection of electrical wires, especially, over a
large range. It may help to put a hand on the
wall next to the detection tool 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 information
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 you want to mark a found object on the
substrate, move the detection tool so that the
object is centered on the center line in the
display. Use the upper marking aid
(1) as well
as the left-hand and right-hand marking aid (5)
to make a mark on the substrate. The center of
the object is located at the intersection point
of the drawn markers.
– Alternatively, move the detection tool to the
left or right until the found object is centered
on one of the two dashed lines in the display.
Then it is located under the corresponding
outer edge of the detection tool. Draw a line
along this outer edge on the substrate and
mark the position of the corresponding lateral
marking aid
(5) on this line. This is the center
of the object.
– The direction of a found object in a wall can be
marked by moving along several offset
measuring paths one after another and
connecting the respective markings.
<Signal View 2D>
The <Signal View 2D> indicates the signal
strength at each measuring point in combination
with the object depth. The
<Signal View 2D> is
a variant of the <Object View> . It displays signal
strengths instead of object symbols. The
maximum signal strength represents the upper
edge of the objects.
