Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect metal objects within people`s carrying parcels, luggage, letters, fabrics and other metal objects. The special appearance of its sensitive surface makes it easy to operate. Better than ring sensor type hand probe. Ultra-high sensitivity, special applications. Such as prisons, chip factories, archaeological research, hospitals, airports and so on. Today we come to understand the hand-held metal detector troubleshooting methods: Phenomenon 1: Symptom: 1-2 seconds after booting, the alarm or vibration is non-stop. Analysis of reasons: generally due to high sensitivity and lack of electricity will appear this phenomenon. After using of a period of time, some users did not notice the battery voltage has been lower than the operating voltage, they often think that is fault which should be repaired in the ordiary factory.. Method of exclusion: 1,adjust lower the sensivity to no alarm when alarming boot. 2, if method 1 can not be excluded, replace the battery or use after charging. Note: lowering the sensitivity at this time does not affect the detection accuracy. Phenomenon 2: Symptom: with vibration of the detector, sometimes the buzzer is working properly, and when transferred to the vibration, the shock motor can not stop. Analysis of reasons: the emergence of such phenomena is generally the user after a period of time did not notice the voltage drop. Because the consumption of the motor more than the buzzer, the voltage at this time can only ensure that the buzzer is working properly. Method of exclusion: 1, in the case of vibration, reduce the sensitivity. 2, replace the new battery or charge and then use Note: lowering the sensitivity at this time does not affect the detection accuracy.
