Method 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.
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.
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.
You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose. You buy from a reputable distributor, and specify the capacitor you want. That way, counterfeits and substitutions are less likely.
There are various brands of capacitors on the market. Made in China, made in Taiwan, Korean and Japan brands. Although the values of the capacitors are the same (eg. 35 volts 2200 uf) some capacitors come out more robust and longer life. How can I measure the difference in quality?
