detected. It is not possible to differentiate between live
and non-live cables. The maximum detection depth is 6
cm (2.3 in).
NOTE
Concrete takes several months to dry out fully.
5.2.4 Floor heating
The "Floor heating" scanning mode is particularly suitable
for detecting metal, metal composite and water-filled
plastic pipes or electric cables under a layer of screed.
The maximum detection depth is 8 cm (3.2 in).
NOTE
Empty plastic pipes will not be found.
NOTE
Pay attention to how the tool is oriented in the area
of heating pipe loops (i.e. end bends in floor heating
systems). It is necessary to scan in several paths and in
both directions.
5.2.5 Drywall
The "Drywall" scanning mode is suitable for detecting
wood beams, metal studs, pipes containing water and
electric cables in drywall partitions. The maximum detec-
tion depth is 8 cm (3.2 in).
NOTE
Empty plastic pipes will not be found.
5.2.6 Hollow brick
The "Hollow brick" scanning mode is suitable for use on
masonry containing many cavities. Cavities are filtered
out to a great extent (i.e. not shown) in this scanning
mode. In this mode, metal objects, water-filled plastic
pipes and live electric cables will be detected. The max-
imum detection depth is 8 cm (3.2 in).
NOTE
Empty plastic pipes and cables that are not live will not
be shown.
5.2.7 Signal view
The "Signal View" scanning mode is suitable for use on all
types of materials. The signal strength at each position in
the scan is shown. This scanning mode makes it possible
to locate closely spaced objects precisely and allows a
better assessment to be made of complexly structured
materials on the basis of signal variations.
The signal peaks are shown as rectangles along the small
scale above the scanning mode indicator bar. Object
depth and, where possible, object class are shown. The
maximum detection depth is 15 cm (6 in).
NOTE
No conclusion about object depth can be reached from
the strength of the signal.
5.3 Distance measurement view
In all scanning modes, the tool can be switched to dis-
tance measurement view. Only the display is switched
over when this is done, not the selected scanning mode.
NOTE
When distance measurement view is selected it is pos-
sible to determine the distance between objects. In the
example shown in the illustration, three equally-spaced
objects are detected. The length of the scan measured
from the starting point is 20.1 cm (7.9 in). The three ob-
jects detected, spaced at a distance of 10 cm (3.9 in)
from each other, are shown as rectangles along the small
scale positioned above the scanning mode indicator bar.
5.4 Materials suitable for scanning
Concrete / steel reinforced concrete
Masonry (brick, cellular concrete, expanded con-
crete, pumice concrete and sand-lime block)
Beneath surfaces such as plaster, tiles, wallpaper,
parquet and carpet
Wood and plasterboard / gypsum board
5.5 Detectable objects
Steel reinforcing bars
Metal pipes (e.g. steel, copper and aluminium)
Plastic pipes (e.g. plastic pipes containing water,
such as in floor or wall heating systems, etc.)
Cavities
Wood beams
Electric cables (irrespective of whether the cables
are live or not)
