How to judge whether the capacitor is good or bad?
Before measuring the capacitance, be sure to discharge the capacitor, that is, after removing the capacitor, short-circuit both ends of the capacitor.
Look at the capacitance of the capacitor tag capacitor to select the appropriate gear. Let's take the 25 microfarad capacitor as an example.
Adjust the multimeter to the capacitor position. The adjusted position should be larger than the capacitance value on the capacitor label. We choose 200 microfarad.
Press the multimeter measurement button, which is usually labeled “Cx/Lx”, which is the measurement capacitor button. When pressed, the display will prompt.
Note that the test leads must be installed in both the COM and Cx jacks.
Finally, the two probes are used to contact the two ends of the capacitor. Generally, the measured value will be too large, but as long as the value is close to the label, the capacitor is normally available.
Be sure to discharge the capacitor before measuring, otherwise the multimeter may be burnt.
