ESR Meters and Measurement Techniques

[eeMattS]

Dave,

I would love to see a blog on ESR meters and measurement techniques.  For example a review and tear down of your ESR meter, a K-7214 kit MK2 kit I believe.  A comparison of the Atlas ESR 60, http://www.peakelec.co.uk/acatalog/jz_esr60.html, and the Ana Tek Blue, http://www.anatekcorp.com/blueesr.htm, would be great!  Also, it would again be great if you could touch on how to measure ESR with a function generator and oscilloscope.

Thanks,
Matt Snyder

I own and use a blue esr meter. Very useful piece of kit.
I used to own a Peak esr meter, but wasn't overly keen on it.
here is a link to measure esr.

Switcher,

Thanks for the reply and link!

Can you please expand on what you like and do not like about each meter?

Thanks,
Matt

The blue esr meter is based on the Bob Parker unit. It works very well with repeatable, reliable, results. The Peak meter seemed to consider every cap I measured had a low esr.
The Peak esr meter's construction is somewhat flimsy. The blue esr meter is a physically larger unit and is of more robust construction.
