You can hook up a digital meter on the volts setting in series with the
cap.  The leakage after full charge up can be read directly from, for
example, one of the cheap 1 megohm input Harbor Freight meters.  Every volt
on that meter is one microamp of current.  I use that scheme to test
tube-era cap checker sensitivity as described here:
