ABSTRACT:
A system for automated testing of the lamp filaments has an ohm meter. The ohm meter is used to determine the resistance of the lamp filament prior to energizing the lamp. A multiplexer switches the ohm meter from one lamp filament to the next so that the lamp filaments are quickly and accurately tested. After the cold resistance of the lamp filaments is measured, a power supply energizes the lamp filaments.
