3.7V Inductor Capacitor ESR Meter Transistor Tester DIY MG328 Multifunction Tester

Features The tester uses 3 7V rechargeable lithium battery battery model 14500 With MINIUSB port it can power the tester or charge for the 14500 battery One key measurement operation auto power off delay Shutdown current is only 20nA support for battery operation Automatic detection PNP and NPN bipolar transistor N P channel MOSFET JFET FET diodes two diodes thyristors resistors capacitors inductors Automatic detection pin definitions Measuring the current amplification factor B of the bipolar transistor and the turn on voltage of the emitter junction Uf Darlington transistor amplification factor can be identified by the high threshold voltage and high current Can detect bipolar transistors and MOSFETs internal protection diodes and displayed on the screen Measuring the threshold voltage and the gate capacitance of the MOSFET Support two resistance measurements the potential can be measured If the potentiometer is adjusted to its end the tester can not distinguish between the middle and the ends of the pin Resistance measurement resolution is 0 1 ohms the maximum value of 50M ohms measurements Capacitance measurement range from 25pf to 100mF 100000 UF Resolution up to 1 pF inductance measurement range 0 01MH 20H otherwise it will appear as a resistor inductor DC resistance is higher than if Europe 2100 will also be displayed as a resistor It can detect 2UF above capacitor equivalent series resistance ESR a resolution of
