AI Customer ServiceMethod 1: pointer multimeter measurement. 1, check the electrolytic capacitor with the resistance meter of multimeter. The two lead wires of the electrolytic capacitor can be divided into positive and negative.
The specific method is: contact the two leads of the capacitor with the red and black meter pen, remember the size of the leakage current (resistance value) when the pointer swings back and stops, and then connect the positive and negative lead of the capacitor short, and then test the leakage current after adjusting the red and black meter pen.
When checking its quality, the resistance of the electrolytic capacitor (6V or l0V) with lower voltage withstand should be placed in R 100 or R 6550 Such electrolytic capacitors are good. The larger the capacity of the electrolytic capacitor, the longer the charging time, the slower the pointer oscillating.
Exceeding the permissible temperature on the capacitor surface (every increase in operating temperature of 7 K cuts life expectancy in half). 2.Overvoltages, overcurrents and high in- rush currents even if they only occur briefly or cyclically (a continuous increase in the operating voltage of the capacitor of 8 % cuts life expectancy in half).
If the capacitor is small, then impedance is high, and less AC current flows to the start winding. If the capacitor is big, then impedance is low, and more AC current flows to the start winding. You can reason through the implications from there.
Fixed capacitors with large capacitance (more than 1 mu F) can be used to measure the capacitor's two electrodes with a multimeter resistance file (R Then try again by switching the test rod. The larger the swing, the greater the capacitance of the capacitor.
