Abstract
A rotary capacitor electrical test system for providing a power source to a capacitor under electrical test can include at least one programmable voltage source, at least one programmable current source, and a controller for programming the voltage and current sources. Random access, non-volatile, memory can be provided for storing information and for providing read/write capability for the controller. At least one digital/analog converter can communicate between the controller and the programmable voltage and current sources. A diagnostic program is operable through the controller for testing internal integrity of basic input/output functions of at least some subsystems. A circuit health monitoring program can operate through the controller for periodically testing and determining internal integrity of at least some subsystems. A self test program can operate through the controller for determining if at least some internal subsystems are working properly on a test/fail basis.
