The T22 metal detector meets the technical specifications and environmental testing requirements for metal detectors in the international market. Specific technical requirements, testing requirements, and inspection rules, such as:
1. Power Supply:
3VDC powered by 2 1.5V batteries; operating time: not less than 40 hours
2、Indicator:
2.1、Visual inspection: LCD LCD display
2.2、Sound - Speaker or Headphone
3. Display and Function Selection:
3.1, the machine starts up and displays nine different metals at the top of the screen. When the machine detects an object, an indicator will appear above the corresponding metal.
3.2. The function words on the left side of the standby state are semi-visible. If you need to select a function, press the (MENU) menu key to choose the required function. The selected function word will change from a semi-visible shadow state to a solid display. After selecting the required function, press "+" or "-" to increase or decrease the machine's parameters.
3.3、DEPTH is the depth indication when detecting an object.
3.4、The mode words on the right side of the standby state are semi-visible. If you need to select a mode, press the (MODE) mode key to choose the required function. The selected function word will change from a semi-visible shadow state to a solid display.
3.5、When detecting metal, the middle will show the value of the object. The more valuable the metal, the higher the value.
4、Menu:
4.1 SENS: Sensitivity;
Press the MENU button to select 'SENS.' Then press the '+' or '-' to adjust the sensitivity level, with a total of 10 settings.
4.2 VOLUME：声音量；
Press the MENU button to select 'SENS.' Then press the '+' or '-' to adjust the sensitivity level, with a total of 20 settings.
4.3 NOTCH: Selective Masking.
NOTCH is a feature that allows users to select any one or more metals to shield from the detector based on their needs or preferences.
5、Mode:
5.1 JEWELRY: (简称：珠宝模式)
This mode is set up to search for jewelry.
5.2 COIN：(简称：硬币模式)
This mode only tests the following currencies: 5¢, 1¢, 10¢, 25¢, 50¢, 1$
5.3 ARTIFACT：(简称：文物模式)
This mode is configured to search for cultural relics, small iron objects cannot be detected, and large iron objects can be detected.
5.4 CUSTOM：(简称：自定义模式)
This mode allows customers to set a pattern based on the metal they want, and it can be programmed with a tone.
Custom Mode Programming Tone Steps:
Set the machine to CUSTOM mode;
② Long-press the MODE button for about 1 second.
Press the MENU button to adjust the metal that needs to be changed to a different pitch.
④ Use the '+' and '-' keys to select the pitch (0=VCO, 1=bass, 2=low, 3=medium, 4=high)
6. PINPOINT (Abbreviation: PP Precision Positioning Mode)
PINPOINT is used when users detect metal within their range but cannot precisely identify the object's location. To operate the machine, raise the detection disk to a height of 8-10CM from the ground. Hold down the PP button in the middle of the machine, and the LCD will display the number 10. Slowly lower the machine. Measure up and down within the range. If an object is detected, the number will change. The smaller the number, the closer the object is. The sound will also increase from low to high. (This function can only locate the depth and position of the object, and cannot distinguish the type of metal.)
7、Backlight function:
The backlight button on the right side of the machine allows you to turn the backlight on or off.
Factory reset function steps: ① Turn off the machine; ② Press the MENU button, while simultaneously pressing the power button (Note: This reset will delete any settings you had previously in any mode).
8、Work frequency: 7.7KHZ
9. Working Current:
When not detecting metal, the working current should be less than 30mA. When detecting metal and the loudspeaker is emitting sound, the current should be less than 60mA. When the LCD backlight is on, the additional current should be less than 15mA.
10. Detection sensitivity:
Turn on the machine and adjust the sensitivity (SENS) to 9. Insert a 25-cent coin into the probe. Move the probe in a uniform speed at a height of 20cm above the center of the probe, and the LCD screen should display the corresponding indication. Meanwhile, the speaker should emit a high-pitched sound.
Work mode is set to PP, take a 25-cent coin, place it at the center above the probe, slowly lower the probe towards the center, the LCD screen should have corresponding indications, and the speaker should make a noticeable sound change.
11、Temperature:
Working temperature range: 0°C (4 hours) ~ +45°C (4 hours)
Storage temperature range: -20°C (8 hours) ~ +60°C (8 hours)
