INTRODUCTION
The Phenix Model 635-5P is a portable AC Dielectric Test Set for performing dielectric strength
tests primarily on vacuum bottles. The test set may also be used for testing other samples which
are no load or light load (< 1 mA) in nature. A built-in self-protection feature current limits the
short circuit output current to safe levels, preventing damage to the test set. Under dead short
conditions, the output voltage will drop to zero.
