5. Mode:
5.1 JEWELRY: (referred to as: jewelry mode)
This mode is set for finding jewelry.
5.2 COIN: (Coin mode)
This mode only tests US dollars: 5￠, 1￠, 10￠, 25￠, 50￠, 1$
5.3 ARTIFACT: (hereinafter referred to as the Artifact Model)
This mode is configured to find artifacts, small iron objects cannot be detected, and large iron objects are detected
5.4 CUSTOM: (Short for: Custom mode)
This mode allows customers to set a mode according to the metal they want, and the tone can be programmed.
Custom mode Programming tone steps:
① The machine is adjusted to the CUSTOM mode;
Press and hold the MODE key for about 1 second;
③ Press the MENU key to adjust the metal that needs to change the tone;
④ Select the tone by the "+" and "-" keys (0=VCO, 1=bass, 2=low, 3=medium, 4=high)
6, PINPOINT (referred to as: PP precise positioning mode)
PINPOINT is used when the user detects the metal within the range during use, but cannot accurately confirm the location of the object. Specific operation to raise the machine detection disk from the ground 8~10CM. Often press the PP button in the middle of the machine, the LCD will display the value 10. Slowly put the machine down. Go up and down the range. If you measure an object, the value changes. A smaller number means closer to the object. The sound goes from low to loud. (This function can only locate the position and depth of the object, and cannot identify the type of metal.)
7, backlight function:
The backlight button on the right side of the machine enables the machine to turn on or off the backlight.
Steps to restore factory Settings: ① Shut down the machine; Press and hold the MENU key while pressing the Power key (Note: This reset will delete your previous Settings in any mode)
8. Working frequency: 7.7KHZ
9. Working current:
When no metal is detected, the operating current should be less than 30mA. When metal is detected and the horn sounds, the current should be less than 60mA. When the LCD backlight is on, the increased current should be less than 15mA.
10. Detection sensitivity:
After turning on the machine, the sensitivity (SENS) will be adjusted to 9, take a quarter coin, 20cm above the center of the probe, and move back and forth at a constant speed. The LCD screen should have corresponding instructions, and the speaker will sound a high tone.
The working mode is placed on PP, take a 25 cent coin, the height of 20cm above the center of the probe disk, and slowly approach the probe disk, the LCD screen should have corresponding instructions, and the sound of the speaker has a significant change.
