AC85V-265V 18W LED Tester TV Backlight Tester LCD TV Maintenance Detection Device Multipurpose LED US Plug black

About this item

• Adaptive voltage, current, automatic identification of lamp beads and light strips. 0-300V adaptive voltage, suitable for most series-parallel lamp bead testing. Digital display, real-time voltage output, with adjustable voltage inside, the voltage value can be self-corrected. High brightness, no need to remove the screen can light up the LCD TV screen. Output voltage and output current automatic detection, support test different sizes LED backlight and lamp beads. Features: Using high-speed microcontroller to do voltage sampling test and drive LED lights to display voltage, to achieve board integration and reduce the bad rate (due to the constant current, only has the voltage display function). Digital display, real-time voltage output, with adjustable voltage inside, the voltage value can be self-corrected. Digital meter using green light-emitting tube, the display for 00 is to indicate a short circuit, display 300V is open circuit. Each group of LED strip of the same LCD TV should show the same voltage. Adaptive voltage, current, automatic identification of lamp beads and light strips. 0-300V adaptive voltage, suitable for most series-parallel lamp bead testing. When testing, the use of progressive starts, the voltage automatically adapts, the current gradually increases, never burn the lamp beads, three to five seconds to reach the normal brightness. With light bars and light beads positive and negative reverse connection protecting function, will not burn the light bar and light beads. Hot, cold and ground isolation, never electrocution. Power cord and box integrated design, easy to carry out. High brightness, no need to remove the screen can light up the LCD TV screen. (There are bad lamp beads of the same screen lit, LCD TV is generally divided into several groups in parallel, you can see which group voltage is different through the voltage, so as to determine which group of LED lamp beads are damaged). Note: This version is a high brightness version, when testing, please do not looking directly at the lamp beads, so as not to hurt the eyes. In the uncertainty of the positive and negative pole, please use 19V voltage detection positive and negative pole, prohibit the use of 300V voltage detection, 300V voltage may cause equipment damage, short connection sac pen positive and negative three seconds, high and low voltage switching.
