How to Use:
After connecting to a mobile phone, observe the current first, the instrument can handle the following situations:
1. Power on and short circuit (use the regulated power supply to supply power to the mobile phone (set the standard voltage to connect the positive and negative poles), the power supply will play the meter and an alarm will sound at the same time)
2. Press the power button and the high current exceeds 500 mA.
3. Small current and fast shaking.
4. Be able to clearly know that a short circuit has occurred somewhere in the circuit, but cannot find a device that is truly short circuited.
5. Use other cheats to explore by yourself.
If the phone can't be boiled many times, it can be assisted by smoking the hair with pine cigarettes. Find the heating element and remove it and then test the short circuit.
