FREQUENT PROBLEMS
PROBLEM
CAUSE
SOLUTION
The metal detector
finds false positives
The coil is being moved too
quickly or at the wrong angle.
Move the coil more slowly and
parallel to the ground.
The metal detector might have
encountered a highly oxidised
object.
Try to locate the object by moving
the
instrument
in
various
directions.
If
the
instrument
reading
changes
every
time
depending on the direction of
sampling, the object is most likely
very oxidized metal.
The metal detector
does not display the
correct type of metal
when it detects an
object
There might be more than one metal object in the area that you are
sweeping.
The object may be a type of metal that the instrument does not
recognise.
If the object is very oxidised the instrument may not report the
correct type of metal.

CARE AND MAINTENANCE
Keep the metal detector dry. If the instrument gets wet, dry it immediately
with a soft cloth. Liquids might contain minerals that could corrode electronic
circuits.
Use and store the metal detector in environments with a normal
temperature
(+5°C ÷ +40°C). Extreme temperatures can shorten the life of electronic
devices, damage batteries, and deform or melt plastic parts.
Keep the instrument away from dirt and dust that can cause premature wear
of parts and components.
Handle the metal detector with care. Dropping the device may damage the
internal circuits and the structure causing malfunctions.
