Capacitor resistance measurement

Yes, I use REW for this and it works great, I need to put my test jig in a case though so I don't have to assemble it every time I use it.

This LC meter is your best bang for the buck:

And quite a few variations of this available on Amazon as well... Might be faster to get.

So you mean, just apply the leads under the continuity test? That is really the only test to do with a DMM?

What happens is the DMM is charging the capacitor using a fixed (low) voltage through some internal resistance. As the voltage slowly builds up on the capacitor, the charging current decreases. It is actually not a resistance but electrical charge build-up on the capacitor. A certain time constant is associated with it, depending on the capacitance and the internal resistance of the DMM in this measuring mode. It is possible to measure the capacitance by measuring the charging time; some instruments measure capacitance on this principle.
