Testing Capacitors part 1

This video shows the way I was shown back in 1962 how to test capacitors for leakage using an ohm meter by an old time radio & tv man.

Thanks, that was very helpful! I have a bunch of capacitors and resistors I need to go through in a wired circuit... one of them is bad, and I have no idea which one. Now I can do a basic test. Thanks for sharing.

@Zylstra555 I am glad it was helpful.

Thanks for stopping by.

I like your video. It is honest and it is real. Keep up the good work.Lots of young folks need the experience you are sharing with them. Make some more videos.

@essoterric Thank You very much, but sad to say I no longer have a shop or test equipment.

never trust anyone who still has a moving meter multimeter on their bench. the correct way to check esr on an electrolyte is to monitor the series frequency response of a 100 khz signal with an oscilloscope

@mikewm9v The BEST way to test a capacitor is to put the RATED voltage on it and monitor the current leakage.

Been doing that for many years.

I was using the ohm meter ONLY to show how I was taught and is NOT the right way, you need to do it like I discribed above.

WHOAH! that's quite a collection of equipment you have; thanks for uploading this. I'm surfing youtube for videos about electronics to complement my online course; this is very helpful.

years ago i took a home tv and radio course from coyne eleltric school and they showed how to test capacters in a similar way. useing a voltage source from a radio and an ohmeter. the only thing you couldnt do was see what the capacitance was. this was field expediant way to do it. not for lab work

Wow HP actually made something cool. :-) Great Video and thanks for the class.

Thank you !

If I recall corrrectly, the H-P 410C has no battery for the resistance measurements. 0.6V is derived from an internal power supply.

well the component tracer is good for smaller values , the problem nowadays are caps on the secondary of switching power supplies. caps that used to last years at 60 hz just dont make it at 100 khz frequencies. the real problem is the electrolyte used in the parts. that is a byproduct of fish oil because of the scarcity of petroleum products.Thus the smell when heated with an iron
