Key features and performance 1. Inductor and capacitor test display - The DC resistance value of an inductor is shown as a resistance reading (example: 2100 ohms). - When testing capacitors, the display shows Vloss and damping. - A larger reading indicates higher impedance and potential capacitor degradation; a smaller reading indicates better capacitor performance. 2. Automated measurement with battery operation - One-key automatic testing with a delayed auto-off. - Auto-off current is 20 mA. - Supports battery-powered operation. - Measures resistors and can also measure potentiometers. - If the potentiometer is set to an end position, the tester cannot distinguish between the middle pins and the end pins. - Resistance measurement resolution: 0.1 ohm; maximum measured value listed as 50 mOhm. 3. Automatic component recognition - Automatically identifies PNP and NPN bipolar transistors, N- and P-channel MOSFETs, JFETs, diodes, dual diodes, thyristors, resistors, capacitors and inductors. - Pin definitions are detected automatically. 4. Transistor parameters, capacitance and inductance ranges - Measures the current gain (hFE, B) of bipolar transistors and the forward voltage (Uf) of the emitter junction. - Transistors can be identified by their high threshold voltage and high current gain. - Capacitance measurement range: 25 pF to 100 mF (100,000 μF). - Capacitance measurement resolution: up to 1 pF. - Inductance measurement range: 0.01 MHz to 20 hours; otherwise the component is shown as a resistance.
