Fangrui Product Details 1. Added Boot Voltage Detection Function. Automatic Detection Of Npn And Pnp Istors, N Channel And P Channel Mosfet, Diodes (including Dual Diode), Thyristor, Istors, Resistors And Capacitors And Other Components, 2. Automatically Test The Pin Of The Elements And Display It On The Lcd. The Positive Bias Voltage Of The Emitter Istor Can Be Determined By Detecting The Amplification Factor And The Base Of The Istor, The Mosfet Protection Diode, Etc. 3. Measurement Of Gate Threshold Voltage And Gate Capacitance Of Mosfet. Display Using 12864 Lcd Lcd (128 * 64 Characters). 4. Higher Test Speed, Effective Component Test: In 2 Seconds (except For The Larger Capacitor, The Measurement Of Large Capacitance Also Takes A Long Time To Measure The Time For 1 Minutes Is Normal). 5. A Key Operation, The Boot Test, A Key To Get. Power Consumption Off Mode: Less Than 20 Na. Automatic Shutdown Function, You Can Avoid Unnecessary Waste, Save Battery Energy, Improve The Life Time. Type: B-module Pcb Size: 63x71 Mm Weigh
