◆The LED is detected as a diode, and the forward voltage drop is higher than the normal value. ◆It can display the symbol of the correct direction for two diodes, and display the forward voltage drop at the same time. This function is very important for detecting capacitance performance.

◆It can detect the equivalent series resistance (ESR) of capacitors above 2UF with a resolution of 0.01 ohm.
If the DC resistance of the inductor is higher than 2100 ohms, it will also be displayed as resistance. The resolution can reach 1 pF, and the inductance measurement range is 0.01MH-20H, otherwise, it will be displayed as a resistance. ◆The capacitance measurement range is from 25pf to 100mF (100,000 UF). ◆The resolution of resistance measurement is 0.1 ohm, and the highest measurement value is 50M ohm. If the potentiometer is adjusted to one end of it, the tester cannot distinguish the pins in the middle and both ends. ◆Support the measurement of two resistances, and the potentiometer can also be measured. ◆Measure the threshold voltage and gate capacitance of MOSFET. ◆The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen. Darlington transistors can be identified by high threshold voltage and high current amplification factors. ◆Measure the current amplification factor (B) of the bipolar transistor and the conduction voltage (Uf) of the emitter junction. ◆Automatically detect PNP and NPN bipolar transistors, N and P channel MOSFETs, JFET field-effect transistors, diodes, double diodes, SCRs, resistors, capacitors, and inductors. ◆Exclusively increase the power switch to avoid battery consumption during storage and shutdown. ◆One-key operation automatically turns off the power.
