1. Ergonomically designed and built to quality standards for point measuring high voltage. 2. Easy to handle. 3. The ground wire features a plug connected to the tester and an alligator clip at the other end. 4. Designed to test CCFL lamps. Avoid generating high-voltage arcs that may damage the lamp. 5. Ideal for testing LCD screens, CCFL advertising signs, and HID headlight angel eye systems. A reliable tool for maintenance professionals. When repairing LCD screens or HID headlight angel eye systems, it can be difficult to determine whether an issue originates from the CCFL tube or the inverter board—especially when observing faint shadows on dark screens or encountering inverter protection. This tester helps quickly identify the source of the problem. Compatible with CCFL lamps ranging from 3 inches to 55 inches. Features a red push-button ON/OFF safety switch. Connect the included 12V DC adapter (not included) to power the tester—the LED turns green to indicate power is ready. High-tension voltage is generated at the probe tip when the button is pressed, and the LED turns red to indicate active testing mode. Press and hold the button for 3 seconds to deactivate—LED turns green (standby mode). Input: DC 12V, 2A Compatible with: 3–55 inch displays CAUTION: 1. Do not connect the lamp to the tester for extended periods. Always ensure the probe tip makes direct contact with the lamp’s end terminal. 2. Exercise caution to avoid exposure to high voltage.
