MK328 Transistor Tester ATmega328 8MHz Digital Triode Capacitance ESR Meter With 1.8 Inch LCD Screen

Feature 1 The processor uses high performance microcontroller ATmega328 using an external 8MHz crystal oscillator as the system clock 2 With 1 8 inch LCD screen a resolution of 128X160 supports 65 536 colors 3 Single button operation support for automatic shutdown for reducing power consumption 4 Supports battery power supply shutdown current is less than 20nA 5 Each measurement time is about 2s only measuring capacitance or inductance the measurement time becomes longer 6 Automatic detection of NPN PNP bipolar transistor N channel P channel MOSFET and JFET diode dual diode P IGPT thyristor thyristor and so on For some thyristors and thyristors when the transistor tester can not meet the trigger current and hold current requirements The transistor tester can not test IGPTs that drive more than 5V 7 Support for pin identification test components 8 Support for bipolar transistor current amplification factor and base emitter turn on voltage test 9 Through the turn on voltage and current amplification factor you can determine the Darlington transistor 10 Supports the gate threshold voltage of the test MOSFET the gate capacitance and the drain source on resistance RDSon at 5V gate voltage 11 Support simultaneous measurement of two resistors data in four decimal format display Support potentiometer test but when the potentiometer is adjusted to one end this time can not distinguish between the middle pin and this pin 12 The minimum resistance r
