The following horns electrolytic capacitors, bolts electrolytic capacitors; the detection of the electrolytic capacitor: A  because the electrolytic capacitor than the average fixed capacitor is much larger, Therefore, the measurement should be selected for different capacity suitable range. Based on experience, under normal circumstances, the 47μF between the capacitors, the available R × 1k block measurement, capacitance greater than 47μF available R × 100 block measurement. B  the multimeter connected with negative red table pen, black pen then positive, new to the moment, the multimeter pointer to the right deflection larger skewness (for the same power to block the greater the capacity, the greater the swing), and then gradually to the left rotation, until it stopped at a certain location. At this point the resistance is positive leakage resistance of the electrolytic capacitor, this value is slightly larger than the reverse leakage resistance. Practical experience shows that the leakage resistance of the electrolytic capacitor should generally be more than a few hundred kΩ, otherwise, will not work properly. In the test, if positive, the phenomenon of reverse no charge, the hands do not move, then the capacity of the disappearance or the internal circuit; If the measured resistance is very small or zero, indicating a large capacitor leakage or breakdown damage can no longer use. C  electrolytic capacitor of unknown positive and negative signs can be used to distinguish the above-mentioned measuring leakage resistance. Ie, the first measure any leakage resistance, remember its size, and then switching table pen measured a resistance. Two measurements in the resistance big time is a positive connection, the black pen then is positive, the red pen then is negative. D  use the Multimeter block, the forward and reverse charge method is adopted to the electrolytic capacitor, electrolytic capacitor according to the size of the pointer swings to the right, can be estimated.
