Sweep the metal samples you prepared 2 to 3 inches (5-8cm) above the centre of the
search coil in turn, the detector will respond with a "DI" tone,and the pointer will swing
to the right for one time.
Note: You have to move the metal objects,as the metal detector is in the motion mode.
If you don't move the metals,the detector will not respond.
When rotating the SENS knob from "0" to "10", and changing the height of the metal
samples in the same time,you will find that the sensitivity of the detector becomes
higher.
5. If you want to classify the metal types, you should use the "DISC" knob. Set the MODE
switch to "DISC", "VOLUME"to the mid position,and "SENS"to "10".
Eliminate iron:
Set the DISC/TONE knob to "0",the unit will respond to any metal objects with a "DI"
tone,and the pointer will swing for one time.
