راه اندازی

1. گیره تمساح را وصل کنید: Securely attach the large alligator clip to a known good ground point (negative terminal of the battery) or a positive power source, depending on the circuit you intend to test. The test light is bidirectional, allowing flexibility in connection.
2. پروب را آماده کنید: Ensure the sharp stainless steel probe is clean and free from debris. The probe is designed for piercing wires or contacting terminals.

دستورالعمل های عملیاتی

جلد عمومیtage تست کردن

1. Connect the alligator clip to a known good ground (e.g., vehicle chassis or battery negative terminal).
2. Carefully touch the sharp probe to the circuit point you wish to test.
3. صفحه نمایش LCD میزان صدا را نشان می‌دهدtage reading. If the circuit has voltage, the display will illuminate and show the measured DC voltage.

Polarity Testing

The test light is bidirectional. If the alligator clip is connected to ground, the display will show positive voltage when the probe touches a positive circuit. If the alligator clip is connected to a positive power source, the display will show negative voltage when the probe touches a ground or negative circuit.

Fuse and Signal Line Voltage تست کردن

1. Connect the alligator clip to a suitable ground.
2. Carefully touch the probe to each side of a fuse or to a signal line.
3. یک جلدtage reading on both sides of a fuse indicates the fuse is likely good. No reading on one side suggests an open fuse.
4. For signal lines, the display will show the voltage present, helping to diagnose signal integrity.

با استفاده از نور پس زمینه

The LCD display features a backlight, which automatically illuminates when a voltage is detected. This ensures clear readability of voltage values even in dimly lit environments.
