How to use a multimeter to detect damaged electronic products or household appliances?
For electronic product maintenance, home appliance repair or computer brain maintenance, everyone has their own methods, and we cannot generalize. Generally speaking, the multimeter is just a tool with many functions (that is, it can measure many parameters). By proficiently measuring the parameters of each segment of the circuit or each component, and its synthesis, the fault can be judged. For example, by measuring the voltage of a certain circuit to determine whether it is working normally; by measuring the resistance of a certain component to determine whether it is normal; by measuring the capacitance of a certain component to determine whether it is open circuit, short circuit or deterioration . . . . wait. So the multimeter is just a tool. After you buy it back, all DIY fans should also go to various forums or participate in amateur classes to strengthen their own quality and improve the ability to use tools. Finally, to make an analogy, a multimeter is like a sword. Its power lies in its owner. As much as there is martial arts (electronic knowledge), it can exert as much effect as possible.
