Automatically detect PNP and NPN bipolar transistors, N and P channel MOSFETs, JFET field effect transistors, diodes, double diodes, SCRs, resistors, capacitors, and inductors. Automatically detect pin definitions. One-key measurement operation, the power will be automatically turned off after a delay. The shutdown current is only 20nA, which supports battery operation. Measure the current amplification factor (B) of the bipolar transistor and the conduction voltage (Uf) of the emitter junction. transistors can be identified by high threshold voltage and high current amplification factor. The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen. Measure the threshold voltage and gate capacitance of the MOSFET. Support the measurement of two resistances, and the potentiometer can also be measured. If the potentiometer is adjusted to one end of it, the tester cannot distinguish the pins in the middle and both ends. The resolution of resistance measurement is 0.1 ohm, and the highest measurement value is 50M ohm. Capacitance measurement range is from 25pf to 100mF (100,000 UF). The resolution can reach 1 pF, and the inductance measurement range is 0.01MH-20H, otherwise it will be displayed as a resistance. If the DC resistance of the inductor is higher than 2100 ohms, it will also be displayed as a resistance. It can detect the equivalent series resistance () of capacitors above 2UF with a resolution of 0.01 ohm. This function is very important for detecting capacitance performance. It can display the symbol of the correct direction for two diodes and display the forward voltage drop at the same time. LED is detected as a diode, and the forward voltage drop is higher than normal. The double LED is detected as a double diode. The light-emitting diode willflash during detection. The time for each test is about two seconds, only large capacitance and inductance measurements will take a long time. colour:Photo color Material:abs size:about 6 x 4cm Package Contents: 1 x M8 Transistor Tester Only the above package content, other products are not included.
