Precautions for using a multimeter to measure capacitance 1. Before using it, you must remember to reset it to zero. This step is very important, and many friends will forget it. If it is not reset to zero, it will affect the detected results. 2. If the detected data is inaccurate, then you can first adjust the range to the maximum value, and then slowly switch it to a small value, so that this problem can be solved, and the pointer should be at one-half of the place.
3. When measuring, you must remember to cut off the power supply, and do not operate with power on, otherwise there will be certain safety hazards, and everyone must take protective measures. Also keep in mind that you must never touch the part with metal with your hands, so as to avoid electric shock and affect the test results. 4. If the capacitor is broken, it needs to be replaced with a new one. When buying a capacitor, remember to choose a big brand. The quality of this capacitor will be better, so it is not a problem to use it for 10 years and 8 years.
