The two leds are used for displaying the condition of a transistor. Digital 12864 lcd display easy to read. This is about the simplest conceivable test circuit so don t expect super accuracy.
Can be powered by 9v battery not.
This is the article about the first version of the transistor tester by markus f. Transistor tester uses a high speed si gate cmos device 74ahct00d as its main component that has quad 2 input nand function compatible with low power schottky. T belong to tp2 at right side of the test socket is the smt test pad also have number to identify each. When test two lead component resistor capacitor inductor the two lead can select any two test point.
