One Multimeter That Can Test All Components?
During my early days in electronic repair, i always thought that one multimeter can accurately check on all electronics components. After many years in this repair trade i can conclude that one has to have different meters to check on different components. At current moment there are no single meter that can test on all electronic components. To test coil we need coil tester, to test resistor we need Ohm meter, to test electrolytic capacitor we need ESR meter, to test non polarity capacitors we need Digital capacitance meter and so forth. If you use analog or digital multimeter to test on different components, although you got the result, the result would not be accurate and this can misled you into believing a bad component is actually good. You will waste tons of time for troubleshooting that you cannot find the answer in the circuit board.
If you have some budget get the appropriate meters so you can accurately test on different type of components. Meters are like assistant to you. More good meters will help speed up your work and at the end of the day you will repair more equipment thus bringing in more profit. When you want to invest on any meter think of the outcome and how it can help you in making more money and not think of how much you waste on that meter. Different thinking approach will usually make you more successful than others.
