[volt-nuts] Anyone know how to make stable inductors?

[Azelio Boriani]

Found the HP manual as suggested by Will: it is now clear where the
capacitor is connected. On page 1 of the manual changes (page 3 of the
PDF file) there is a very clear drawing of the quasi-inductance
standard. The "C" port has no guard connections and is used to test
the capacitor alone.
