Abstract
In an embodiment of the present invention, an automated diagnostic tester system is configured for use with a lighting fixture connected to a power source and including at least one of a ballast connected to the power source, a capacitor connected to the ballast, an ignitor, and a high intensity discharge lamp connected to the ballast. The tester system includes an electrical connector system capable of being interconnected as part of the lighting fixture, providing circuit access at least to the power source and to the high intensity discharge lamp. This enables interruption of at least one of (i) the connection of the ballast to the power source and (ii) the connection of the high intensity discharge lamp to the ballast. An automated diagnostic tester is connected to the electrical connector system and is operable to automatically measure lighting fixture parameters including at least at one of power source voltage, ballast open circuit output voltage, ballast output current, ignitor pulse voltage and lamp operating voltage.
