ABSTRACT:
The embodiment of the invention disclosed herein is directed to a gas tube tester which provides a pair of terminals for connection to the external electrodes of a cold cathode gas discharge tube. The tester includes one circuit for applying a progressively increasing voltage across the discharge tube so that the breakover voltage of the tube can be determined, this breakover voltage being registered on a meter. A second circuit is provided for testing the leakage current of the gas discharge tube within predetermined limits. A leakage current corresponding to a one megohm internal resistance is sufficient to render conductive a programmable silicon controlled rectifier to give an indication of excessive leakage current.
