25v 4700uf 0.00 esr

[shaunbt123]

i have tested the above capacitor with my esr meter,and its showing 0.00 ohms esr, does this indicate a faulty cap, from what i have seen the lower the esr the better.
thank you.

Well, it seems good to me!

Generally, when capacitors fail, the ESR goes up. So, that one is probably good. 0.00 just means that it's lower than your meter can measure.

Brand and series of the capacitor in question? Possible your ESR meter is at the limits of the measurement (cannot display beyond certain range). Does the capacitor measure as a short when using a multimeter continuity test?

yes. try lexwalker advice. maybe just the esr meter couldn't measure it or that is shorted caps. try to measure this caps with lower ohms scale on your meter. if shorted the ohms reading will be same as this esr meter value, just like when you put your meter probes short together.

ive checked the spec on my peak atlas esr 60 meter,and it reads from 0.01Ω to 20.0Ω. i will test it tommorow with my multimeter on ohms range.
