Capacitor Leakage Measurements Using a Model 6517A Electrometer
... • Set the 6517A to measure current. • Set the 6517A for autoranging. Once these commands are issued, the program checks to see if the operation has been completed prior to sending any further commands. This gives the 65l7A the appropriate amount of time to be configured. After the initial setup, the ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
