I finally broke down an purchased the AADE L/C meter after I got tired
of doing the calculations required when using my homebrewed K6OLG LC
Tester (the AADE meter is based on that LC Tester). I believe it is a
bit more trustworthy for small values than the typical DMM with
capacitance and inductance measurement capability, but if all you have
is the DMM, it can be a big help. Some DMM LC measurements can be quite
accurate, but I would not trust the exact measurements on a DMM until it
has proven its worth - give it +/- 20% uncertainty until you prove it is
more accurate - and remember that the leads contribute to stray
inductance and capacity too, so your measurement fixture can be a big
factor when measuring small values.
