1. If the DC resistance value of the inductor is 2100 ohms, it will also be displayed as resistance. When testing the capacitor, the 'Vloss' displayed on the screen represents loss and attenuation. The larger the value, the closer the capacitor is to being scrapped! Impedance is also displayed. The smaller the value, the better the capacitor performance! 2. A measurement with automatic shutdown after a delay. The shutdown current is only 20 mA, supporting battery operation. It supports resistance measurement, and potentiometers can also be measured. When the potentiometer is set to one end, the tester cannot distinguish between the middle pins and the end pins. The resistance measurement resolution is 0.1 ohms, and the measurable value reaches 50 milliohms. 3. Automatic detection of PNP and NPN bipolar transistors, Nchannel and Pchannel MOSFETs, JFET fieldeffect transistors, diodes, double diodes, thyristors, resistors, capacitors, and inductors. Pin definitions are automatically identified. 4. Measure the current amplification factor (B) of the bipolar transistor and the forward voltage (Uf) of the emitter junction. Transistors can be identified by their threshold voltage and current amplification factor. The capacitance measurement range is from 25 pF to 100 mF (100,000 µF). The resolution can reach 1 pF, and the inductance measurement range is 0.01 mH to 20 H. Otherwise, it will be displayed as resistance.
