Features Microcontroller The capacitance inductance resistance meter uses the microcontroller to run smoothly, no jamming, it is a good helper for you to detect transistors, diodes, etc. LCD Display The capacitor ESR inductance resistance meter can display the results on a 128x64 graphic LCD display, the readings are intuitive and clear, and the work is convenient One button operation The MK328 ESR transistor tester meter can realize automatic shutdown by one-key operation, easy operation, energy saving and improving work efficiency Shutdown current: the switch-off current of the MK328 ESR transistor tester is only approx. 20nA, which affects the accuracy of the associated resistance. Use a thousand cent film resistor, and the remaining percent is also a thin film resistor. Application MK328 ESR transistor tester can automatically detect NPN and PNP bipolar transistors, N and P channel MOSFETs, JFETs, diodes, dual diodes, thyristors and triacs. Functions: Works with microcontrollers. Displays results on a 128x64 graphical LCD display. One button operation with automatic power shutdown. The shut-off current is only about 20 nA. Automatic detection of NPN and PNP bipolar transistors, N and P channel MOSFETs, JFETs, diodes, double diodes, thyristors and triacs. Package includes: 1 x transistor tester Package List
