Features: Intelligent regulation of voltage and current. No burning lamp, no electric shock, reverse protection. High brightness, accurate judgment. Wide voltage, input and output barrier-free. Double isolation, security protection. High and low pressure can be switched. Multiple light sources can be tested: test any LED lamp strip, lamp board COB light source, single lamp bead, etc. No need to remove the screen: test LED TV backlight and other LED backlight of any size without detaching screen. Test voltage: Test the voltage parameters of various components, such as voltage stabilizing value of voltage regulator and voltage withstand value of electrolytic . DC voltage: Testing the voltage value of DC power supply (less than 300V) can be used as DC voltmeter. Test circuit: Turn-on and leakage of test circuit.
