This DIY transistor tester module is LCR-T7 graphical multi-function tester for resistor + capacitor + SCR + diode + transistor + mos tube inductance, 12864 LCD display with backlight and the backlight color is generally green. It's powered by one 9v battery. If prolonged power, you can use two 8.4v lithium battery pack. 

Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes(including dual diode), thyristors, transistors, resistors and capacitors and other components. 
Double-sided circuit board, ensuring the fastness of wire terminals.
Micro-controller uses 8MHz external crystal for better measurement accuracy.
The 12864 LCD screen can display measured data and graphics with backlight.
Main chip dual in-line with a socket, perfect for electronics enthusiasts upgrade or replacing the chip.
When powered by 9V voltage, the stable operating current is about 20mA.

Add boot voltage detection function.
Automatically test out the pin element and displayed on the LCD. 
Can be detected to determine the transistor emitter forward bias voltage of the transistor, MOSFET protection diode and the amplification factor of the base.
Measure the gate threshold voltage and gate capacitance of the MOSFET. 
High test speed, valid component test: 2 seconds (except in the larger capacitor of large capacitance measurement also takes a long time, the measured time of one minute is normal). 
One-button operation, automatically detect and shutdown.
Power consumption off mode: less than 20nA. 
Auto power off function to avoid unnecessary waste, save battery power and improve battery life.
Can generate a square wave signal of 1hz-2mhz.
