Hand-Held Metal Detectors (BW-SJAJ50)

Technology Parameter

Description

It is simple and convenient to use without adjustment. There are two options of high and low sensitivity. The alarm mode includes sound and vibration. It has the function of startup, shutdown sound or vibration prompt. When the battery runs out, there is automatic continuous sound or vibration alarm, and there is an external charging jack

Test distance of metal articles: pin 10mm, 1 yuan coin 60mm, 6-inch wrench 120mm

Startup detection:

Turn on the power switch and hear the "click" sound for about 3-5 seconds, indicating that the power has been connected, the self-test time is completed and can be used normally, At the same time, the green light is on. If the green light is not on, it indicates that the battery is not installed or the battery is in poor contact; If the continuous sound, vibration or barking is not stopped, it means that the battery can not be used again, and the battery should be replaced

Sound and vibration change-over switch selection:

Press the yellow button switch, and the alarm mode is vibration. Release the yellow button switch, and the alarm mode is sound

High sensitivity test:

After the power is turned on, the high-sensitivity detection can be carried out. Hold the handle and sweep the detection surface around the tested object. When there are metal objects, the alarm sound or vibration will be sent out, and the green light will turn into red light; Stop detection and scanning, stop the alarm sound or vibration, and the red light turns green.

Low sensitivity test: 

If you need to eliminate the small objects in the metal objects, you can press and hold the low sensitivity switch to probe and scan around the measured objects. When there are metal objects, the alarm sound or vibration will be sent out, and the green light will turn into red light; When the detection and scanning are stopped, the alarm sound or vibration will stop, and the red light will change to green light. Because the sensitivity is reduced by more than 5 times, the measured metal objects are generally large

Sensitivity adjustment: 

If the detection distance fails to meet the specified requirements or the sensitivity is too high to cause instability or sound or vibration without metal detection and scanning on the human body, the sensitivity shall be adjusted. Put the sound and vibration change-over switch in the "release" state, use a small slotted screwdriver to extend into the small hole on the handle of the detector, rotate counterclockwise to make sound, then rotate counterclockwise to make no sound, and then rotate clockwise for half a circle, Until the sensitivity meets the requirements
