The G66 metal detectors meet the technical specifications and environmental test requirements of metal detectors in the international market The specific technical requirements, test requirements, inspection rules, etc. are as follows:
1. Power supply
2 9V batteries (Battery not included)
2. Indicator
2.1 Visual inspection: LCD liquid crystal display screen
2.2 Sound speakers or headphones
3. Display and function selection:
3.1. After starting up, there are 10 metal feature classifications on the top of the display screen When using the machine to detect objects, an indication will appear above the corresponding metal
3.2. DEPTH is a deep indication when an object is detected
3.3. To change the mode in standby mode, press the switch/menu button to select the desired mode The selected mode will be highlighted in black
3.4. When metal is detected, the numerical value of the object will be displayed in the middle The more precise the metal, the higher its value
4. Menu:
4.1 SENS: Sensitivity;
Press “↑” and “↓” to adjust the sensitivity, which is divided into 0-99 parts
4.2. Volume;
Press “+” and “-” to adjust the volume
4.3. Selective shielding
Users can choose to shield any one or more precise metals according to their needs or preferences when using the detector It can only be used in jewelry mode and coin mode Press the mode key, the square above will flash, and then press ↑ or ↓ to move and then press the mode key to block or cancel
5. Mode:
5.1 (referred to as Jewelry Mode)
This mode is set for searching for Jewelry
5.2 (abridged as coin mode)
This mode only tests US dollars: 5, 1, 10, 25, 50, 1$
5.3 (abridged as all metal mode)
This mode has no shielding and all metals can be detected
6. PINPOINT (abbreviated as PP precise positioning mode)
PINPOINT is used when the user detects metal within the range during use, but cannot accurately confirm the position of the object The specific operation is to raise the detection plate of the machine 8-10cm above the ground Press and hold the PP button in the middle of the machine frequently, and the LCD will display the numerical value Slowly lower the machine Measure up and down within the range If an object is detected, the value will change The higher the numerical value, the closer it is to the object The sound will also increase from low to high (This function can only locate the position and depth of objects, and cannot differentiate the type of metal.)
7. Automatically balance:
Press the balance button and move up and down at a height of 3-5 cm on the ground When you hear a “drop” sound, it indicates that the automatic balance has been completed
8. Manually balancing:
Press and hold the local balance key while holding down ↑ or ↓ to manually adjust the local balance
9. Backlight function:
The backlight button in the middle of the machine turns the backlight on or off
10. Steps to restore the factory settings function: In the shutdown state, press and hold the mode key, hold it down while turning on, and wait until the display is fully displayed to indicate that the factory settings have been restored
11. The working frequency is approximately 7.7KHz
12. Working current:
When not detecting metal, the working current should be less than 55mA When detecting metal and the horn sounds, the current should be less than 80mA When the LCD backlight is lit, the increased current should be less than 45mA
13. Detection sensitivity:
After turning on the machine, adjust the sensitivity to 75-80, take a 25 cent coin, move the probe to a height of 28cm above the center of the dial, and move it back and forth at a constant speed The LCD screen should have corresponding instructions, and the horn should emit a high sound
The working method is to place it in PP, take a 25 cent coin, and approach the probe slowly downwards at a height of 28cm above the center of the probe The LCD screen should have corresponding instructions, and the sound of the horn should have a significant change
14. Temperature:
Working temperature range: 0 ℃ (4 hours)~+45 ℃ (4 hours)
Storage temperature range: -20 ℃ (8 hours) to+60 ℃ (8 hours)
