I use a BK Precision 879B and can only say good things about it, saved me numerous times (and also exonerated components I thought were faulty). http://www.bkprecision.com/products/component-testers/879B-4-count-dual-display-handheld-lcr-meter-with-esr.html Looks like the Der EE is an even

I can put in another vote of confidence for this one. I have one from Portugal (because I didn’t know about the this-side-of-the-pond source) and it works as advertised. - Mark On Sep 30, 2015, at 12:54 PM, John Robertson wrote: > On

Re: ESR Meter Recommendations

Ken, I don't have personal experience with those but I can tell you those would only be good for the smaller electrolytics and not the big ones in the power supply. For those you will want an older capacitor tester made for big caps, Hallacrafters, Heathkit and Solar made ones that would go up

Ken, I have two of the Atmega328 uC based 'swissknife' testers you mention, cost about $25 ea. on eBay, and have been exceptionally happy with them. They're a brilliant little piece of instrumentation, and IMHO no electronics hobbyist should be without one. For quick testing & ID of SS
