sweep wand near metal object. The metal should be detected as wand sweeps by t he object,
the alarm will sound or vibrate when near metal, green light will illuminate red when me tal is
detected. It will retur n to green and s ound or vibration wil l stop when no met al i s near sensor field.

4) Low sensitivity test: If you need to exclude the very small metal objects, you can hold down
the low sensitivity switch (6). Then conduct exploration sweep around the measured object,
alarm will only sound when metal is large enough to detect as the wand sweeps by the object ,
the alarm will sound or vibrate when near metal. The light will illuminate red when metal is
detected. It will retur n to green and s ound or vibration wil l stop when no met al i s near sensor field.
