Dy294 Digital Transistor Dc Parameter Tester Field Effect Tube Tester Multifunction Semiconductor

DY294 is mainly used for testing the DC parameters of manifold semiconductors such as diode, transistor, controlled silicon and field effect transistor.It also can be used to test the with stand voltage of capacitor, protection voltage of varistor and isolation of electrica . Meanwhile it also can test 78 and 79 series three-terminal voltage regulator. Measuring forward voltage, reverse voltage, forward saturation voltage drop, amplification factor, reverse leakage current of various crystal diode, audion, silicon controlled rectifier(), field effect transistor(FET).Measuring rated working voltage of chemical capacitor, DY294 Ta capacitor, Leaded multilayer ceramic capacitor, high voltage lacker.Measuring protection voltage of varistor Colour:As Shown Material:ABS Package Contents: 1 x DY294 digital transistor DC parameter tester Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
