Hello, I got this nice old server with Delta DPS-275BB-1 A Rev 04 server PSU.
The PSU was pulled from working Pentium II 350Mhz computer.
Started to test caps as to keep the PSU for other tasks like mini-itx etc.
I have the ESR70+ meter. But I'm just new to measuring caps so I'm not sure how to interpret the measurements here.
Manuals of Atlas ESR70 meter and then Anatek BlueESR, two most respectable (and expensive) meters, you will see that their recommended capacitor ESR values are very different.
(blue esr 1.6ohms) and (atlas 16ohms) seems like a typo in the manual doesn't it?
(blue esr 0.6uhms) and (atlas 2ohms) more than 2x difference.
So what chart is better? Caps are caps and there should be agreement what is considered low enough ESR for a cap to work properly.
These tables both seems like nonsense then, one of them is wrong.
If there is no baseline what caps are low enough ESR then what are we measuring again?
If capacitors are advancing and new caps have lower ESR, then respectable measurement equipment manufacturer should give tables by year. Usually on every equipment there is a sticker with model number and year, else you can just google the thing.
Anatek and Peaktek are not respectable measurement equipment manufacturer then, no such tables are provided.
But then what about the Agilent, Fluke etc.
