The correct use of handheld metal detectors

2018-07-06
The correct use of handheld metal detectors is as follows:
1. Turn on the power switch and hear a [beep" sound, indicating that the power is on and the green light is on. If the green light does not light, it means that the battery is not installed or the battery is not in good contact. If the sound continues to vibrate continuously or continuously, it means the battery can no longer be used. It should be replaced with a new one.
2, sound, vibration transfer switch selection: press the red button switch, the alarm mode is vibration. Release the red button switch and the alarm mode is sound.
3. After turning on the power, you can perform high-sensitivity detection. The wing technology reminds you that the hand grip handle sweeps the detection surface around the object to be tested. When there is metal object, it will sound an alarm or vibrate. At the same time, the green light turns red. Light; stop sweeping, alarm sound or vibration stops, red light turns green.
4. Low sensitivity test: If you need to eliminate objects with small volume in the metal, you can press and hold the low sensitivity switch. When the metal object is swept around, the alarm sound or vibration is emitted. At the same time, the green light turns into a red light; when the sweep is stopped, the sound or vibration stops, and the red light turns into a green light. Because the sensitivity is reduced by more than 5 times. Therefore, the measured metal is generally a relatively large metal.
5. Sanjibao Technology reminds you that sensitivity adjustment should be made if the detection distance does not meet the specified requirements or the sensitivity is too high to cause instability or sound or vibration when there is no metal detection in the human body.
6. Put the sound and vibration switch in the "release" state, use a small flat-blade screwdriver to extend from the small hole in the detector handle to rotate clockwise, adjust to the sound, then turn counterclockwise until it just sounds. Then rotate a half turn counterclockwise until the sensitivity meets the requirements.
