Testing Electrolytic Capacitor
Since after got the ESR meter i hardly test the capacitance value of electrolytic capacitor. Normally whenever the ESR value shoot up the capacitance value would be out too so there is no point on checking the value of the capacitance. However in some very rare cases the ESR value of an e-cap is okay but the capacitance value may be down. Usually if i really could confirm that a particular section have problem and my ESR value did not reveal any bad e-cap then i will use my digital capacitance meter to test out the e-cap value. I’m mentioning it again that this type of situation is very rare and usually with an ESR meter you could easily detect a bad cap. If you have any comment about ESR meter tested good on e-cap and failed when check with digital capacitance meter i would like to hear from you-thanks!
