Specification: Item Type: LED Backlight Tester_x000D_Material: ABS_x000D_Input Voltage: 85-265V_x000D_Measurable Voltage Range: 0-300V_x000D_Measurable Current Range: 40-60mA_x000D_Power: 25W Features: 1WIDE USAGE: LED TV backlight tester can be used to test LED lamps, LED panels, individual LED beads, COB light sources, LED TV backlights, monitors, computers, etc. 2SUPERIOR QUALITY: LED tester adopts high speed microcontroller to do voltage sampling test and drive LED light to display voltage, realizing board integration and reducing defect rate. 3SAFETY: 0?300V adaptive voltage, suitable for most series and parallel lamp bead testing. it adopts a progressive start method, the voltage automatically adapts to the current gradually increasing, will not burn the lamp beads 4ADJUSTABLE: The LED TV backlight tester uses a digital display with real time voltage output, with adjustable voltage and self?calibrating voltage values. 5INTEGRATED DESIGN: LED TV backlight tester can be isolated from hot and cold ground, so it will never be electrocuted. The power cord and case are integrated for easy transport on the go. PackageList: 1 x_x000D__x000D_LEDBacklightTester 2 x Test Pen
