Product Detailed
1.DUOYI DY294 Digital Transistor Parameter Tester Semiconductor transistor tester 2.paypal accepted 3.100% brand new

  

DY294, the Digital Transistor DC Parameter Tester, is mainly used for testing the DC parameters of manifold semiconductors such as diode, transistor, controlled silicon and field effect transistor. DuoYI 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.

DuoYI DY294 tester has adopted the large scale integrated circuit for analogue/digital conversion. With high sensitivity and accuracy, DuoYI DY294 adopts liquid crystal display which can be read directly. With compact structure and convenient operation, DuoYI DY294 is portable and especially suitable for inspection and screening of devices and components in electronic factories as well as application of DuoYI DY294 technicians engaged in electronic work, lab staff, maintainers and radio fans.

DY294 ApplicationsMeasuring forward voltage, reverse voltage, forward saturation voltage drop,amplification factor, reverse leakage current of various crystal diode, audion, silicon controlled rectifier(SCR), field effect transistor(FET). Measuring rated working voltage of chemical capacitor,terylene capacitor,DuoYI DY294 Ta capacitor,Leaded multilayer ceramic capacitor,high voltage lacker. Measuring protection voltage of varistor. DuoYI DY294 Measuring starting voltage of neon bulb, neon lamp. Measuring constant voltage value of 78,79 series three-pole circuit.
