Multi-functional transistor tester for automatic detection of NPN and PNP transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor. Also can be used as square signal and PWM signal generator.

Features:
Digital LCD backlight display for easy readings, can display measured data and graphics.
Micro-controller uses 8MHz external crystal, the measurement accuracy is better.
One key operation(long press the button and enter the menu selection), automatic power shutdown.
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Can be powered by 9V battery(not included).
Can automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor.
Support 2 resistors measurement, also support potentiometer measurement.
Resistance measurement resolution is 0.1 ohms, 50M ohms can be measured.
Automatically test the pins of a component and show on the display.
Measure the gate threshold voltage and gate capacitance of the MOSFET.
Measure bipolar transistor current amplification factor and base-emitter threshold voltage.
Can be used as signal generator and frequency meter: built-in square signals from 1Hz-2MHz and can generate 1-99% PWM(pulse width modulation) signals.

Notice: 
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
Users need to add an interface with some components by themselves if they want to measure the frequency(1Hz-2MHz)!
