Description
LED TV LCD Backlight Tester, AC 85-265V 18W LED Lamp Bead Lamp Strip Tester, Maintenance Repair Tools, EU US AU UK Plug
1. Voltage sampling test: High-speed single-chip microcomputer is used for voltage sampling test, and LED lights are driven to display voltage (by no means other products on the market use the purchased voltage meter head, which is installed separately) to realize the integration of boards and cards and reduce the defective rate (due to constant current , only for voltage display function.)
2. Adaptive voltage: 0-300V adaptive voltage, suitable for testing most series and parallel lamp beads. During the test, the gradual start-up method is adopted, the voltage is automatically adapted, the current is gradually increased, and the lamp beads will never be burned, and the normal brightness can be reached after 3 to 5 seconds. The positive and negative poles of the light bar and lamp bead are reversed, and the light bar and lamp bead will not be burned.
3. Real-time display: Digital display real-time voltage output, with adjustable voltage inside, the voltage value can be corrected by itself. The digital meter uses a green light-emitting tube, and the display of 00 means a short circuit, and the display of 300V means an open circuit. Each group of LED light bars of the same LCD TV should display the same voltage.
4. Easy to carry: Isolated from hot and cold, never get an electric shock. The power cord and machine box are designed in one piece, which is easy to carry when going out.
5. No need to disassemble: You can light up the LCD TV screen without dismantling the screen. (The screen with broken lamp beads lights up like the same. LCD TVs are generally divided into several groups connected in parallel. You can see which group has different voltages through the voltage, so as to judge which group of LED lamp beads is damaged). During the test, do not look directly at the lamp bead due to the highlighted version. So as not to hurt the eyes.
