- I'd recommend first buying either a dedicated LC or LCR meter from eBay. If you are in the US you'll be able to get one delivered to your door for about $70.00 . Do an Ebay search for either "Inductance" or "Inductance Meter" . This will bring up a handfull of returns for new product available online within the US. Typically, there are also a few Hong Kong sellers & a couple of Australian vendors of these speciallized meters. ( Get a meter that has more than a 20uF capacitance range , as its' top range ).
