How to use a multimeter to detect damaged electronic products or household appliances?
A: This question is very complicated, or it makes me ask the wrong question. For electronic product maintenance, home appliance maintenance or computer brain maintenance, everyone has their own methods, and it is impossible to generalize. In general, a 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 their synthesis, the fault can be judged. For example, by measuring the voltage of a certain circuit to determine whether it is working properly; by measuring the resistance of a component to determine whether it is normal; by measuring the capacitance of a component to determine whether it is open, short-circuited or deteriorated . . . . and many more. So the multimeter is just a tool. After DIY fans buy it back, you should bubble in various forums or participate in amateur classes to strengthen your literacy and improve the ability to use the tool. Finally, for example, a multimeter is like a sword. Its power lies in its owner. With a few percent of martial arts (electronic knowledge), it can play a few percent of its effects.
