Short three test terminals, enter into the testing period, the screen displays calibration steps. Each testing time is about two seconds, only the large capacitance and inductance measurements requires a long time. Dual LEDs detected will be displayed as double diode, and the LED is blinking simultaneous in testing process. LED detection shows diode, the forward voltage drop is higher than normal. It can display symbols of two diodes in right direction, also shows the forward voltage drop. This function is very important in testing the capacitor performance. It can detect 2UF or higher value capacitor of equivalent series resistance (ESR), the resolution is 0.01Ω. Resolution up to 1 pF, inductance measurement range: 0.01MH-20H, otherwise it displays it as a resistor, if DC resistance of inductor is higher than 2100Ω, it will also be displayed as a resistor. Capacitance measurement range: 25pf to 100mF (100000 UF). Resistance measurement resolution is 0.1Ω, the maximum measuring value is 50MΩ. If adjusting the potentiometer to its end, the tester cannot distinguish the difference between the middle and the ends of the pin. Support two units of resistances measurement, and measurement of potentiometer. Measuring the threshold voltage and the gate capacitance of the MOSFET. Can detect bipolar transistors and MOSFET’s internal protection diodes and display it on the LCD screen. Darlington transistor amplification factor can be identified by the high threshold voltage and high current. Measuring the current amplification factor (B) of the bipolar transistor and the turn-on voltage of the emitter junction (Uf). Automatically detect PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET FET, diodes, two diodes, thyristors (SCR), resistors, capacitors, inductors. Shutdown current is only 20nA, support 3.7V battery operation and micro USB port 5V power supply. One button measuring operation, automatic power off.
