Newest Version Of Inductor Digital Display Capacitor ESR Meter DIY MG328 Multifunction Test Diy Electronic PCB Board

About transistor Multifunction Tester: The tester uses 3.7V rechargeable lithium battery (battery model: 14500 NOT INCLUDED) powered portable design, but you can use the T-MICROUSB outlet to charge the battery and power the system for a long time in the indoor use of more economical and convenient, eliminating the need always to be replaced battery of economic input! Features: 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 MOSFET's internal protection diode
