I need some help on a couple of issues. First, I am new to using the CapAnalyzer 88A. I have tested caps on my Tempest boards and on a couple I get a DCR low signal (DCR setting at 150 ohms). I turn the DCR ohms down and the error on those caps doesn't go away until I get it below 10 ohms. I assume this means the caps are bad. Once I set it below 10 ohms and it's gets into test, the ESR test passes.
I did a study today as I was curious with the readings on my board with a couple of caps that were in the yellow on the analyzer. I took most of the extra new caps I have bought over the last 3 years and tested them right out of the bag. At least 1/2 of them fail or are in the yellow. Is this right? Can the new caps be bad?
What is the best brand of cap to buy?
