In this review video, part 2 of 2, I measure various components with the DIY M12864 Transistor Tester that can be found on banggood.com, and compare a few with a multimeter measurements.
Part 1, soldering the pieces: https://youtu.be/cvPgaKA1kW4
-capacitor ESR, includes a function for "in-circuit" measuring;
-transistors (BJTs, MOSFETs, JFETs), Triacs, Thyristors;
Can generate square-wave frequency and PWM signal;http://www.banggood.com/DIY...
