|If you only want to identify
sick electrolytic caps...
If you want to identify electrolytic caps causing a fault rather than knowing their exact condition, this simple tester might be what you're looking for.
It's a real in-circuit ESR meter with the same protection as the others on this site, but has a simple "Go/No Go" display. It has distinctive beeps so you don't need to look at it.
