- Încărcarea bateriei: Connect the provided Micro USB cable to the charging interface on the tester and to a 4.5V USB power adapter (not included). The charge indicator LED will show the charging status. It will turn green when fully charged. Avoid using chargers with voltage peste 4.5V.
- Pornire inițială: Press the "Start" button to power on the device. The display will light up, and the tester will perform a self-check.
- Conectarea cablurilor de testare: For components that cannot be inserted directly into the ZIF socket, use the included test clips. Connect the clips to the corresponding test points (1, 2, 3) on the tester.
6. Instrucțiuni de utilizare
The LCR-TC1 tester is designed for automatic component identification and measurement. Follow these steps for testing various components.
6.1. Procedura generală de testare
- Ensure the component to be tested is discharged, especially capacitors.
- Connect the component to the tester. You can use the ZIF socket for multi-pin components or the test clips for others. Ensure good contact between the component leads and the test points (1, 2, or 3).
- Press the "Start" button. The tester will automatically identify the component type and measure its parameters.
- The results will be displayed on the TFT screen.
- The device has an automatic shutdown function to conserve battery. It will power off after approximately 20 seconds of inactivity.

- Rezistoare: Connect the resistor leads to any two of the test points (1, 2, or 3). The tester will display the resistance value.
- Condensatoare: Connect the capacitor leads to any two of the test points (1, 2, or 3). Ensure the capacitor is discharged before testing. The tester will display capacitance, ESR (Equivalent Series Resistance), and Vloss.
- Inductori: Connect the inductor leads to any two of the test points (1, 2, or 3). The tester will display the inductance value and DC resistance.
- Diodes (including Double Diodes): Connect the diode leads to any two test points. The tester will identify the diode type and display forward voltage and reverse current.
- Transistors (NPN, PNP, MOSFET, JFET, IGBT): Insert the transistor leads into the ZIF socket, ensuring each lead (Emitter, Base, Collector for BJT; Source, Gate, Drain for FET) connects to a different test point (1, 2, or 3). The tester will identify the type, pinout, and measure parameters like hFE, Ube, Vt, Cgs, etc.
