Medicine, food, and commercial quality inspection systems;
Precious metal detection (such as gold and silver jewelry factories), and other security checks.
Notes:
1. If the sensitivity is set too high, the device may continuously alarm; reduce the sensitivity if needed.
2. Turn off the power after use. Do not remove the battery for long periods to avoid damaging the circuit.
3. When the probe detects metal, it will emit a crackling sound, which stops only when the metal continues to be swept.
4. When turned on, if the green light turns dark and continuous alarm sounds, it indicates the battery voltage is low—replace the battery immediately.
