that is characteristic of the reaction to a copper coin or other object made of non-
ferrous metal. If you orient the sheet perpendicular to the sensor, in this case it will
be identified as a steel object according to the sound. If you perform the same
operation with an aluminum sheet, in all orientation cases, the sound reaction of
the device will only be a response to the non-ferrous object. Thus if audio signals
of Uniscan 7215M during scanning, combine both intermittent and continuous
sounds, the object is either steel or contains steel fragments. Hence, there is one
important practical recommendation. In case of difficulty identifying objects by an
audible signal, more accurate information on object can be obtained by orienting
the sensor with respect to the object in various ways.
