The operation process of the metal detector
RESET (reset reset button) FREQ (detection sensitivity and frequency adjustment knob) VOLUME (alarm volume adjustment knob) OFF (power off) BATF (battery self-test indicator) ALLM (detection gear) DISC (detection gear and automatic identification metal type block)
The specific operation of the metal detector is as follows:
1. Turn on the machine, point the knob to the BATT pointer, and the battery capacity percentage will be displayed:
2. Turn the knob to the ALLM state, then the green light and the blue light will light up at the same time, indicating 100, and the speaker will sound an alarm when the VOL is turned up.
3. Press RESET (reset to zero) to make the instrument enter the initial state, no light and no sound.
4. Then turn off the volume to a moderate level, adjust FREQ, and perform detection sensitivity. Generally, when the adjustment is adjusted to 4.5.6, the green light will turn off and turn on, and the pointer indicates that there is towering sound in the speaker at 18-25 (individual instruments It is normal to have a deviation in the middle), the sound of ditata is about 60 times per minute, and this operation is carried out without any detection object.
5. In this way, we can enter the detection state. The best ground detection distance is between 5 cm and 7 cm. When a metal object is detected, the green light will flash quickly or stay on when the watch needle swings sharply, and there will be a rapid alarm sound in the speaker , the blue light will be on (the blue light is generally the main criterion for detecting objects). We can determine the size of the object according to the range of the blue light on and off, and can locate the depth of the object. Above we can use the pointer, and the blue light degree of differentiation for a comprehensive analysis.
6. If we want to approximate the type of metal, turn the indicator to DISC to enter the type identification state, and analyze the type of metal according to the size data indicated by the hands. The index of non-ferrous metals is small, and the index of steel is large. (The above operations are all manual operations)
The automatic operation status of Hong Kong Xima AR metal detector:
The automatic state includes: the first step, simulated object detection, the second step, enter the memory function, the third step, fully automatic search control, memory analysis, the fourth step, detection expansion.
