Is It Enough To Have Good Meters?
Of course the more meters you have the better or faster to locate a problem. Now besides meters, having the right schematic diagram and understanding how each section in an equipment work is equally important. Even though you have the best meter in the world but you do not know where to locate the fault or how to find out the problematic section, you will still not be able to solve the problem. For example, if section A problem was cause by section B and your concentration only on section A then you will not find out the problem because the real fault is in section B.
Besides having good meters, you must also know how to accurately test electronic components, perform voltage and scope testing, read schematic and block diagrams, understand how IC’s works (CPU, EEPROM, TTL, Oscillator, Amplifier IC and etc) in order to check the input and output signal, understand the characteristic of each components (to find out which components could breakdown under load)and many more. Once you know the information above, you will have a great advantage of solving lots of electronics problem.
