With a precision potentiometer, better quality, power supply module and breadboard. A key measurement operation , auto power off delay . Shutdown current is only 20nA, support battery operation. Automatic detection PNP and NPN type bipolar transistors , N, P -channel MOSFET, JFET FET , diodes , two diodes, thyristors , resistors , capacitors , inductors. Automatic detection pin definitions. Measurement of the bipolar transistor current amplification factor (B) and conduction voltage emitter junction (Uf). Darlington transistor may be identified by the amplification factor of the high threshold voltage and high current. Can be detected inside the bipolar transistor and MOSFET protection diodes and displayed on the screen.
