Features:►Turn on the tester's power switch; the LCD will not light up, press the test button (TEST button) and the LCD will light up!► If testing devices with high capacitance, inductance and high voltage drop, it is recommended to test the test interface of the tester. Try not to use the test line to avoid large errors caused by the resistance of the test line itself.►The tester is not suitable for applications with high measurement accuracy!► Measureable components: various diodes, capacitors, resistors, triodes, thyristors, MOS tubes, etc.!► It is only used to measure electronic devices and cannot be used to test power devices (high-power mos, thyristors, etc.)!► The instrument has been calibrated at the factory, users do not need to calibrate themselves, can be used directly!Specifications:◆ Built-in 3.7V lithium battery!◆ 12864 graphic LCD display test results.◆ One-button operation, automatically turn off the power, increase the power switch, avoid battery power consumption during storage and shutdown.◆ Automatic detection of PNP and NPN bipolar transistors, N, P-channel MOSFETs, JFETs, diodes, dual diodes, thyristors, thyristors, resistors, capacitors, inductors. Automatically detect pin definitions!◆ It can measure the current amplification factor (B) of bipolar transistor, lower power Darlington crystal and the threshold voltage (Uf) of the emitter junction.◆ The protection diode inside the bipolar transistor and MOSFET can be detected and displayed on the screen.◆ Measure the threshold voltage and gate capacitance of the MOSFET.◆ Supports dual resistance measurement and potentiometer measurement. If the potentiometer is adjusted to the end of the end, the tester cannot distinguish between the middle and the ends.The resolution of the test resistor is 0.1 Ω and the maximum is 50 MΩ.◆ Capacitance measurement range from 25pF to 100mF (100,000Uf) with a resolution of 1 pF. It can detect the equivalent series resistance (ESR
