Great In-Circuit ESR Meter

5.0

I have used several of the cheaper and no-brand knockoff eBay ESR meters and this blows them out of the water in terms of accuracy and ease of use. You don't have to zero it every time you use it, and the tweezer probe makes it easy to test a capacitor one-handed in any situation. I used it to test all of the capacitors in an SMPS and the two capacitors it identified as bad ESR turned out to be leaking on the bottom. Great product, highly recommended. TEquipment sells the real thing too, I've ordered this same product elsewhere and it was DOA.
