(vector position projection schematic drawing of Product adjustment in "0" time )
Red：N-Fe metal;
Blue：Ferromagnetism metal

Green：detect materiel 1
Brown：detect materiel 2;
X axis：Electrical conductivity
Y axis：Magnetic conductivity

 Principle explanation：

To test the electrical conductivity and the magnetic conductivity of detect object. When adjust product in "0", two examinations channels are corresponding precisely the electrical conductivity and the magnetic
