The instrument is able to detect any
material with a minimum of conductivity,
but is NOT able to detect the presence
of plastic materials
The calibration must be performed on a
homogeneous and uniform surface in
order to avoid reading problems. In the
case of a rough surface, place the
instrument on a piece of cardboard
The presence of metal parts inside the
walls can affect the test result
To avoid interference, keep the free hand
at least 15cm (6in) away from the
scanning surface
The instrument
conductive materials in the presence of
walls with depth greater than 18mm
(0.7in) and with objects of minimum size
30x30mm (1.2x1.2in)
The instrument does NOT scan metals
materials in the presence of walls with a
depth greater than 30mm (1.2x1.2in)
and with objects with a diameter greater
than 25mm (1in)
CAUTION
does NOT scan
