Post testing electrolytic capacitors using a multimeter?

I am wondering if there is a technique for testing circuit board mounted electrolytic capacitors in (or out of circuit if nessecary) using a multimeter?

I may have a few bad caps. somewhere on my board and the thought of de-soldering all of them .

anyone please advize? best way to test them with a dmm?

Thanks

My Fluke model 29 has a capacitance testing function. I would test them out of circuit though.

Hi,
Answered your post on the same subject here

The included cap function on multimeters gives you an approximate capacitance value and may catch some problems. But not the most common ones. Just change them since you have them out.
