How to measure the quality of Aluminum electrolytic capacitor

How to measureAluminum Electrolytic capacitorThe quality of the equipment

Method 1:
Use a pointer multimeter to short-circuit the two pins of the capacitor for discharge, and connect the black probe of the multimeterElectrolytic capacitorThe positive pole of the. The red probe is connected to the negative electrode (for a pointer type multimeter, when measuring with a digital multimeter, the probes are mutually adjustable). Normally, the probe should first swing in the direction of low resistance, and then gradually return to infinity. The larger the swing amplitude of the watch needle or the slower the return speed, the greater the capacity of the capacitor. Conversely, the smaller the capacity of the capacitor. If the watch needle does not change at a certain point in the middle, it indicates that the capacitor is leaking electricity. If the resistance indication value is small or zero, it indicates that the capacitor has broken through a short circuit. Since the battery voltage used in a multimeter is generally low, it is more accurate to measure low voltage capacitors. However, when the voltage resistance of the capacitor is high, Although the measurement is normal during operation, there is a possibility of leakage or breakdown when high voltage is added.


Method 2:Measure the capacitance with a digital multimeter and set the gear to the capacitance (select the gear based on the capacitance value you measured). During the test, use two probes to overlap the two pins of the capacitance. The meter has a certain value, and then return to the infinity position. Swap the probes and try again. This time, the displayed data size is slightly off, and then return to infinity, indicating that the capacitance is good. If it cannot return to infinity, it indicates leakage, and if infinity is displayed, it indicates that the capacitance is good, Indicates an internal open circuit or lack of capacity.
