Features Easy Operation: 1 click measurement operation, automatic delayed shutdown. The shutdown current is only 20nA and supports battery power supply. Automatic detection of PNP and NPN bipolar transistors, N, P channel MOSFETs, JFET field effect transistor, diodes, diode, thyristors, resistors, capacitors, inductors. Automatically detect pin definitions. Smart Measurement: Measure the current amplification coefficient B of the bipolar transistor and the conduction voltage Uf of the emission junction. The amplification coefficient of transistors can be identified by high threshold voltage and high current. Clear Display: Can detect the internal protection diodes of bipolar transistors and MOSFETs and display them on the screen. Measure the threshold voltage and gate capacitance of MOSFETs. The Using Tips: Supports two resistance measurements and can measure potential. If the potentiometer is set to the bottom, the tester cannot distinguish between the middle and both ends of the pin. High Accuracy: The resistance measurement resolution is 0.1 ohms, with a maximum measurement value of 50M ohms. The capacitance measurement range is from 25pf to 100mF, that is, 100000 UF. The resolution can get to 1 pF, and the inductance measurement range is 0.01MH‑20H. Otherwise, it will be displayed as resistance. If the inductance DC resistance is higher than 2100, it will also be displayed as resistance.
