Can we use a multimeter to detect the quality of porcelain chip capacitance?
Using a multimeter can only test the capacity of the porcelain chip capacitor, whether there is internal short circuit or leakage, which is not the key factor. The key withstand voltage value of the porcelain chip capacitor cannot be tested with a simple multimeter.
How to observe the quality of ceramic chip capacitor with naked eyes?
In fact, the cutting corners of ceramic chip capacitors are mainly based on chips. For example, we don't buy brand chips, only buy inferior chips from small manufacturers, or use small chips to replace large chips. If we observe with the naked eye, we can observe the diameter of the ceramic chip capacitance. If the diameter is obviously small, it is a problem of using small chips to replace large chips. However, the quality of the chip still needs to be tested by instruments to observe.
