LCR vs ESR meter for in-circuit testing of electrolytic cap
TimFox:
If the total circuit including the device under test is appropriate to the simple ESR meter, then by all means use it to get an indication.
Kean:
An LCR meter will generally be designed for better accuracy rather than in-circuit measurement. ESR measurement is a special case.
I didn't see any mention of in-circuit testing in the specs of the DE5000, but I may have missed it. I don't own one.

Personally, I prefer the Shannon Tweezers ST42.

Best KISS cost effective solution.

I do like my Shannon tweezers, but they certainly wouldn't be the first thing (or even second/third) I'd think of using on suspect electrolytic caps.
I fact, I'm not sure I've ever used them on an SMD electrolytic. They do get used a lot on small SMD parts, 0603 and 0402.
Like the ESR70 they do have the benefit of selecting a very low test voltage.

You need use ST42 more and get to know them better. ;)
