Bob Parker ESR Meters

Re: Bob Parker ESR Meters

What kind of errors did find about the kit?

Re: Bob Parker ESR Meters

I got started on my ESR Meter kit today and discovered that eventhough I ordered a MK2 AND the downloaded manual for the kit is about a MK2 ... then my kit is NOT a MK 2 !!!!!!!!!!!!!

I send the seller a mail so let's see how he reacts

Re: Bob Parker ESR Meters

If you are comfortable doing repair work that requires the use of an ESR meter, you will have no problems building one of these kits.

I'm so sick and tired of these displays going down after a few years

I think the hardest job is to find out where these damned plastic clips are holding it all together.

... but let's see how it turns out - thx anyway !

Re: Bob Parker ESR Meters

What I was thinking of was the KIT-version - any problems with buying that if you are a well skilled electronic hobbyist ?

Re: Bob Parker ESR Meters

Oh, well just scroll back in this thread, several members of badcaps including me have built it, no problems at all I would say

OK, I'll order it right away - thx for the info !

Re: Bob Parker ESR Meters

Well, that model number should be the "MK2" model which I have of Bob's meter.
The casing is different though, only the seller could tell you if it's the same or not, unless you are lucky and find someone that has bought it

Re: Bob Parker ESR Meters

Has any of you experiences with the ERS meter kit "K 7214" from this firm:

Good or bad ?

Re: Bob Parker ESR Meters

I don't know if it's of any use to you, but the EVB ESR meter from Portugal is almost the same as the Blue meter from Anatek Corp. Its web page is at http://clientes.netvisao.pt/greenpal/evb1.htm

Thank you, i was concerned about charged caps but i see that the meter can be ordered with protection diodes.

Re: Bob Parker ESR Meters

hi, i would like to find the blue esr meter for sale in the uk or europe, this is because anything from the US will get me hammered by the dreaded vat and import duty then royal mail also get their pound of flesh, any info appreciated.Thanks in advance.

Re: Bob Parker ESR Meters

Hi, can you help me with a HEX file for blue esr for microcontroller??

I doubt that is going to happen any time soon.

Look on Google, there are many other ESR meter designs available and with source code, if you want to make something yourself.

Re: Bob Parker ESR Meters

ESR... ripple current... hydrogen liberation...

Christ, we're talking about one type of many different components on any PCB - basically if it looks buggered or I think it may be buggered then I replace it, sometimes on a somewhat trial-and-error basis, but almost always with success.

[K7214]

Bob Parker's ESR kit still available!

Caution - blatant, self-serving ad!

If anyone here is looking for the Dick Smith (DSE) K-7214 ESR kit for measuring electrolytic capacitors in circuit please feel free to visit:

http://flippers.com/esrktord-form.html for more info.

I have about 150 left in stock.

PS, for those of you that already have the kit Bob set up a poll to find out if folks wanted the meter continued as a kit or pre-assembled you can find it at the top of our ESR support page:

Re: Bob Parker ESR Meters

Hi Bob...

Thanks for your comment and I really thank you for making this great device.

Cheers,

I'm happy that this meter I originally only designed for me is useful to lots of others who are having problems with Bad Caps.

Just for everyone's information, Dick Smith Electronics down here in Australia has completely gotten out of the kits business. No more ESR meters are going to be produced.

Most of the remaining stock of them is now at John's Jukes in Vancouver, Canada. He ships world-wide and his prices and customer service are good.

His website is at http://www.flippers.com

Re: Bob Parker ESR Meters

Hmmm, OK. Thanks for that.

Re: Bob Parker ESR Meters

Wellllllllllllllll ... these two pages from UCC say it indirectly:
http://www.chemi-con.com/u7002/life.php
http://www.chemi-con.com/u7002/failure.php

The failure chart points out that excessive ripple current causes increase internal pressure. The life page points out that excessive ripple current causes oxide formation on the cathode foil. Hydrogen gas is a byproduct of oxide formation and the cause of the rise in internal pressure.

[Bob Parker]

Re: Bob Parker ESR Meters

Theoretically, the ripple current rating means that if you run caps above that rating, hydrogen gas will be produced, leading to premature failure.

I've just done a whole lot of net searching to find out more about ripple current causing hydrogen liberation in electrolytic caps and can't find a thing. The manufacturers say hydrogen generation is a function of DC leakage, and ripple current simply causes I2R heating.
Can you please direct me to more info on this subject? Thanks.
