This locater is the non-motion metal detector. As long as you approach it, it will
react to all kinds of metals. You can use 25
￠
dollar coin as sample.
2.
Take off the watch, ring and other metal accessories. Let the locater be far away
from the wall, the floor and other metal objects and also the electric light,
television, computer, mobile phone and other electrical appliances that will bring
electromagnetic interference.
3.
Put the 25
￠
dollar on the plastic or wooden table. There mustn’t be any metals
under the table or around the coin, in order to avoid the influence of metal. Lay
the locater above the coin vertically.(See figure.3)
Fig.3
4. Turn on the power supply. The signal strength LED will flash two times, and the
vibrator will vibrate 2 times, the lighting LED will light and the locater will be
balanced automatically. Then it will be in the state of waiting.
Note: Because the impact of the magnetic field or the surrounding
electromagnetic field, the locater may self-excite or reduce the sensitivity when
changing the position or rotation direction. In this time, you should press the balance
button lightly to enter the new balance, so as to maintain the effective detection
sensitivity.
At first, balance it once. Then hold the detector, approach the nether coin slowly
(see Figure.4). When the distance is about 2.5cm to 3cm, the locater begins to react,
the motor begins to vibrate, and the red LED is on. As the locater approach the coin
continually, the motor frequency gets higher and the LED lights in the order of red,
green, blue and white. Until the white LED is shown, the frequency of the motor is
the highest.
