Example of a detection procedure
Example 1: Searching for a wooden beam behind a plasterboard wall.
• Place the detector on a spot on the wall behind which there is guaranteed not to be a beam.
Hold the detector vertically (or horizontally).
Whether the detector is held horizontally or vertically has no effect on the search.
If no such spot is known, simply perform multiple searches one at a time and always start
somewhere else. Of course, if you happen to start where there is a beam, you won't find
anything.
• Turn on the detector and select detection mode
ton (6). The detector has now saved the current value as a reference value. The green LED
should shine, there should be no or few bars in the bar graph, and the signal strength is
close to 0%.
• Move the detector to the left/right or up/down along the wall (not lifting it off the wall), depend-
ing on where you want to locate the wooden beam.
• If the detector detects deviations from the reference value, either the yellow LED (weak
signal) or the red LED (strong signal) will shine. In addition, you will hear a continuous beep.
The red LED will flash if the deviation from the reference value is to strong and you will hear
a beep (in which case, recalibrate in an area where the yellow LED shines, as described
below).
• To better isolate the position of the wooden beam, place the detector on the wall so that the
yellow LED shines or the bar graph is approximately in the middle (medium signal strength).
Do not remove the detector from the wall! Now recalibrate by holding down the button (6)
for 2 seconds.
The green LED should shine, there should be no or few bars in the bar graph, and the signal
strength should be close to 0%.
• Continue the search by moving the detector further to the left/right or up/down the wall.
• You could also perform a recalibration as described above.
• In this way, the position of the wooden beam can be narrowed down even further.
If you want to start again with a "rough" setting, turn off the detector and start all over
again!
Example 2: The search of a metal beam behind a plasterboard wall.
The procedure corresponds to that described in Example 1. However, instead of using but-
ton (6), use button (8).
Perform material moisture measurement
• Two metal pins (9) are located behind a cover (10) for measuring material moisture. The
cover can be easily removed from the detector.
There may be two small plastic covers on the metal pins when the product is
shipped. Remove these before measuring.
After the measuring and cleaning the metal pins, reattach the plastic caps; then re-
place the cover (10).
Briefly press the button (7). The display shows a droplet sym-
bol
(J) and SCAN and the symbol
Hold the pins against the surface to be measured. If necessary,
push the pins slightly into the surface, but do not use force! In
the example on the right, the residual moisture is measured on a
piece of wood. The display shows the humidity value; measure-
ments are being carried out continuously.
If the reading needs to be stored temporarily for easier reading,
briefly press the button (7).
The display message SCAN disappears from the display, instead
the symbol
(G) appears. You can now remove the detector
from the measuring surface and read the message.
To continue measuring, briefly press the button (7). The symbol
(G) will disappear and SCAN is once again displayed.
If you need to stop the material moisture measurement and require detection, briefly
switch the detector off and on again.
Tips and information
• By recalibrating during the search, the reference value can be reset many times. Using this
technique, will greatly improve the search success. When done correctly, wooden beams,
metal pipes or power lines (depending on the locating mode selected) can be found much
easier.
• The detector mainly detects wooden beams, metal pipes and power lines (with mains/AC
voltage).
• Plastic water pipes may also be detected, as water or air in the pipes is recognised as alter-
ing the "normal" quality of the wall. The same applies to plastic drainpipes or other cavities
in a wall.
• To find power lines property, the current must be on.
Current-free power lines can only be detected in the "metal" detection mode. Owing to the
relatively thin copper wires, only limited detection is possible.
Please note: The "AC voltage" detection mode is used to find conductors that carry mains
voltage. Power lines with low voltages or DC voltage are not detected.
• Metal foil-coated insulating material will prevent detection of metal pipes or power lines lo-
cated behind such material.
(Wood) by briefly pressing the but-
.
• The maximum detection depth and recognition quality depends on the type of material and
the size of the object. Larger objects can also be located at greater depths than smaller ones.
• If the red LED flashes and a beep is heard, it indicates an override (excessive deviation from
the reference value). Simply perform a recalibration.
Maintenance and cleaning
The product is maintenance-free for you; you should never dismantle it (except for inserting or
replacing the batteries as described in these operating instructions). Servicing or repair may
only be carried out by a specialist.
Use a clean, dry, soft cloth for cleaning. Do not use aggressive cleaning agents as these can
cause discolouration.
Disposal
a) Product
This symbol must appear on any electrical and electronic equipment placed on the
EU market. This symbol indicates that this device should not be disposed of as
unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose
of it separately from unsorted municipal waste. Spent batteries and accumulators,
which are not enclosed by the WEEE, as well as lamps that can be removed from
the WEEE in a non-destructive manner, must be removed by end users from the
WEEE in a non-destructive manner before it is handed over to a collection point.
Distributors of electrical and electronic equipment are legally obliged to provide free take-back
of waste. Conrad provides the following return options free of charge (more details on our
website):
• in our Conrad offices
• at the Conrad collection points
• at the collection points of public waste management authorities or the collection points set up
by manufacturers or distributors within the meaning of the ElektroG
End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply in
countries outside of Germany.
b) (Rechargeable) batteries
Remove batteries/rechargeable batteries, if any, and dispose of them separately from the
product. According to the Battery Directive, end users are legally obliged to return all spent
batteries/rechargeable batteries; they must not be disposed of in the normal household waste.
Batteries/rechargeable batteries containing hazardous substances are labelled with
this symbol to indicate that disposal in household waste is forbidden. The abbrevia-
tions for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead
(name on (rechargeable) batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations
and contribute to environmental protection.
Batteries/rechargeable batteries that are disposed of should be protected against short circuit
and their exposed terminals should be covered completely with insulating tape before disposal.
Even empty batteries/rechargeable batteries can contain residual energy that may cause them
to swell, burst, catch fire or explode in the event of a short circuit.
