The most info/familiarity will be acquired by just digging into your stock of new electrolytic capacitors and testing them, thus familiarizing yourself with the ranges to be expected. You will particularly notice the variance in the high voltage caps (100VDC-450VDC) and their inherently higher readings versus their low voltage counterparts yet being an in acceptable tolerance range..
