الشكل 5.1: LCR-TC1 tester shown with a Micro USB charging cable and various test clips, indicating readiness for use or charging.
- شحن البطارية: 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 voltagتتجاوز 4.5 فولت.
- التشغيل الأولي: Press the "Start" button to power on the device. The display will light up, and the tester will perform a self-check.
- توصيل أسلاك الاختبار: 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. تعليمات التشغيل
The LCR-TC1 tester is designed for automatic component identification and measurement. Follow these steps for testing various components.
6.1. General Testing Procedure
- 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.
