5 HOW TO USE
This type of metal detector is able to distinguish between ferrous (containing iron) and non-
ferrous metals (gold, silver, copper, platinum, aluminium, lead).
5.1 Switching on the instrument
To turn on the instrument, hold it in a comfortable position, then turn the volume knob
clockwise from the OFF position to the desired volume. As soon as you start to turn the knob
the power light will turn on.
5.2 Resetting the instrument
1. Rotate the volume knob to an intermediate position
2. Rotate the discriminator knob to an intermediate position
3. Keep the search coil at a distance of at least 50 cm above the ground away from
metal parts, press the AUTO TUNE button and hold it down until the needle is pointing
at zero.
It will now be possible to re-press the AUTO TUNE button at any time while taking
measurements to return the needle back to zero.
5.3 Testing and use of the instrument
To learn how to use the instrument and see how it reacts to different metals, the instrument
should be tested before use. The function tests can be done both outdoors and indoors in
buildings.
5.3.1 Testing inside buildings.
1. Remove any metal objects such as rings, watches, bracelets or any other metal objects
that you are wearing.
2. Position the metal detector on a table made of wood or plastic and rotate the search
coil so that it is pointing at the ceiling of the room.
Testing the metal detector
Never test the metal detector on a floor inside a building. Most buildings contain metal parts
in the floors, which can interfere with the objects you wish to test the metal detector with,
making reading unreliable.
3. Reset the instrument as described previously.
4. Move a sample of the element that you wish to find with the metal detector (such as a
gold coin) at a distance of approximately 50 mm from the coil.
Testing the metal detector
When using objects to test the operation of the metal detector, the instrument will capture the
signal more easily if the object is positioned with its largest area parallel to the coil.
