Re: Dell GX620
Most of the 2200s, 820s, and 220 are rubycons. I will check the series and compare the data sheets. Would it be safe to say that 0.00 is a good reading if the capacitance reading on those caps are accurate? The esr 3.1 thankfully also shows cap value and they are pretty accurate at that. Thanks pcbonez this will help a lot.

Re: Dell GX620
I just got my first ESR meter (micro 3.1) and I have some 220uf's from a gx620 that rate at 0.04-0.07. Are these ok? Also have some 2200uf that rate 0.00 ohms. The board I have has no physical sign of bad caps so I'm taking them off one by one.Leave a comment:

Re: what tool identifies bad caps on live circuit?
Well i was just under the impression that the ESR worked On a live circuit lol thanks for clearing it up though. Ill go check them out cuz ~$50 is definitely doable for me.
Edit: so what should i be looking for when using the esr meter that will tell me that a cap is going bad?Leave a comment:

what tool identifies bad caps on live circuit?
can anyone recommend a not-so-expensive tool that will show me if a capacitor is bad? I have a bunch of Dell GX 620s that do not POST, and replacing the caps that clearly looked bad was not enough (some work now though). I think the tool is called a ESR meter or something, but I guess I just need some clarification on what and how to use.. thanksLast edited by speg_head; 06-30-2010, 05:22 PM.
