I've got to throw in a pitch for simplicity. A basic LCD
Display Cap meter can be bought for $49 or less. I've
seen kits by Rainbow and others which adapt a small
circuit and a volt meter to a basic cap value meter.
>From memory, said kits run about $8
-
The el cheap'o cap meter I bought years ago from
Fuji Svea (remember them Rich..?) resolves well
down to less than 5pf. Import cap meters abound
on Ebay and the Electronics Supply Stores.
-
Sometimes one might spend a little money to save a
lot of time. Avoids beating the dead horse again.
-
Real economy and home brew types can find
simple circuits in the handbook which allow one
to measure cap values.
-
Your results will probably vary.
