TV LED Backlight Tester, LCD Digital Display, Portable

• 【Efficient LCD TV Diagnosis】 Skip the hassle of screen removal with this tv led backlight tester that lights up lcd tv screens to identify faulty lamp beads. by detecting voltage differences across parallel groups, you can quickly pinpoint damaged led groups. with an input voltage range and 18w power output, it’s versatile for testing any size led backlight or lamp beads.
• 【Digital Display Real Time Voltage】 Equipped with a bright green luminescence tube digital display, this tv led backlight tester shows real time voltage output with adjustable settings. self correcting voltage values make it easy to identify short circuits (00 display) or open circuits (blan display). ideal for ensuring uniform voltage across led strips in lcd tvs.
• 【High-precision Voltage Testing】 This super tv led backlight tester utilizes a high speed single chip microcomputer for precise voltage sampling and display. unlike other products that use separate voltmeter heads, our integrated design ensures board reliability and reduces defects. perfect for constant current applications with accurate voltage display functionality.
• 【Gradual Starting Mode Safe Testing】Designed for most series and parallel bead tests, this tv led backlight tester features a gradual starting mode that automatically adapts voltage and gradually increases current. this innovative approach prevents burning lamp beads and ensures normal brightness within 3 to 5 seconds. safe for both lamp strips and beads with correct polarity connections
• 【Hot and Cold Isolation Safety】 Experience complete safety with our hot and cold isolation design that eliminates the risk of electric shock. the integrated power cord and box design enhances portability, making it convenient for on the go repairs. perfect who need reliable and safe testing equipment

1. EXCELLENT SINGLE CHIP MICROCOMPUTER: Using high speed single chip microcomputer to do voltage sampling test, and drive LED lamp display voltage (not other products on the market with the purchase of voltmeter head, separate installation), to achieve board integration, reduce the defective rate(due to constant current, only do voltage display function) 2. 0‑ ADAPTIVE VOLTAGE: Suitable for most series and parallel bead tests. Test use gradual starting mode, voltage automatically adapt, current gradually increase, never burn lamp beads, reach the normal brightness after three to five seconds. Lamp strip, lamp bead with positive and negative connection, not burning lamp strip and lamp bead 3. ADJUSTABLE CIRCUIT: Digital display real time voltage output, with adjustable voltage, voltage value can be corrected by itself. The digital meter uses green luminescence tube, the display of 00 is short circuit, the display of is open circuit. Each group of LED strip of the same LCD TV display voltage should be the same 4. INSULATION AND PORTABLE: Hot and cold isolation, never electric shock. Power cord and box integrated design, easy to carry out 5. WITHOUT REMOVING SCREEN: You can not remove the screen, light up the LCD TV screen, there is a bad lamp bead screen lit, LCD TV is generally divided into several groups of parallel, can be seen through the voltage which group of voltage is different, so as to judge which group of LED lamp bead damage 6.TECHNICAL PARAMETERS: Input voltage 85-265V, output voltage 0‑300, power for 18W. Output voltage, current automatic detection. Can test any size LED backlight and lamp beads Spec: Item Type: Super LED Tester Material: ABS How to Use: When testing, do not look directly at the bead due to the highlighted version. So as not to hurt the eyes. Package List: 1 x Tester 1 x Red Test Pen 1 x Black Test Pen 1 x User Manual Notice: 1. When you are unsure
