Subject: ESR Meter Recommendations
I'm going to be working on my 11/730s power supply, so I'm in the market for
an ESR meter. I've seen some (older) recommendations for the AnaTek
'Blue' and various 'Dick Smith' derivatives. However, eBay is flooded
with
knockoff Mega328 based ESR/Transistor/SCR/etc. testers all looking like:
The software is open source and as there is no single supplier "knock off"
isn't perhaps appropriate..

16&keywords=esr+meter
Anyone had any experience with one of these devices?
I have one. I havn't used it for checking ESR but it works at a low voltage so it may
not be effective on big caps. On the other hand this

retails for nearer $130 and when I checked it also measures at 3v. Lots more comments
