Measuring capacitance with a tester
The method for measuring capacitor capacitance with generally available testers is the same as the battery recharging method (apply constant voltage and current to the capacitor to be measured, and measure the electrostatic capacitance from the relationship between the voltage and current once the full charge point is reached). 

Accordingly, there may be a large margin of error with capacitors that have large amounts of current leak (aluminium electrolytic capacitors, etc.), so their measurement values are not reliable.
