HWL300LED tester Backlight tester Multipurpose LED stripe lamp bead testing tool

features: 1 the use of high-speed microcontroller to do voltage sampling test and drive the LED lamp display voltage (never other products on the market using the purchase of the voltage meter head separate installation) to achieve board integration reduce the bad rate (due to constant current only the voltage display function.) 2 0-300V adaptive voltage suitable for most series-parallel lamp bead test. When testing the use of progressive start the voltage automatically adapts the current gradually increases will never burn the lamp beads three to five seconds after the normal brightness. Light bar light beads positive and negative polarity connected to reverse not burn the light bar and light beads. 3 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 a short circuit display 300V is an open circuit. The same LCD TV of each group of LED light bar display voltage should be the same. 4 hot and cold ground isolation never electrocution. Power cord and box integrated design easy to carry out. 5 you do not have to remove the screen light up the LCD TV screen. (There are bad lamp beads of the same screen lit LCD TVs are 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) 6 the test due to the high-bright version please do not look directly at the lamp beads. To avoid injury to the eyes Product parameters: Name: LED lamp beads light bar tester Input voltage: 85-265V Output voltage: 0-300V Power: 18W Color: black white Plug: EU plug UK plug AU plug US plug Output voltage current automatic detection. Product use: No disassembly screen LED backlight LCD TV maintenance testing lamp beads lamp strip lamp board lamp strip tester point lighter can test any size LED backlight and lamp beads. High brightness no need to remove the screen can determine the backlight is good or bad. Operation specifications: Adaptive voltage current automatic identification of lamp beads and light strips. Input voltage:85-265V AC. output voltage:0-300V DC 0-19V DC Can test the lamp beads and a variety of good and bad light board light bar (individual lamp bead damage as bright as possible) Short connection sac pen positive and negative three seconds high and low voltage switching Notice: 1. Please use 19V to detect positive and negative polarity when you are not sure prohibit the use of 300V voltage detection 300V voltage may lead to damage to the equipment short connection sac pen positive and negative three seconds for high and low voltage switching 2. Free screen LED backlight LCD TV repair test lamp beads lamp strip light board light bar tester 0-300V high brightness free screen version: input voltage: 85-265V output voltage: 0-300V power 18W. 18W. output voltage current automatic detection. Can test any size LED backlight and lamp beads. High brightness no need to remove the screen can determine the backlight is good or bad. Package list: 1*Host 1*meter pen 1*Instruction book
