DY294 is mainly used for testing the DC parameters of manifold semiconductors such as diode, transistor, controlled silicon and field effect transistor. DY294 also can be used to test the withstand voltage of capacitor, protection voltage of varistor and isolation of electrical. Meanwhile DuoYI DY294 can test 78 and 79 series three-terminal voltage regulator.
