Goodhd LED Backlight LCD TV Maintenance Detection Lmp Bead Lamp Strip Tester

Features: - Made of high quality materials durable -High speed single-chip microcomputer is used for voltage sampling test and LED lamp is driven to display voltage (by no means other products on the market use purchased voltmeter heads which are installed separately) to achieve board card integration and reduce defective rate (because the current is constant only the voltage display function is used.) -0-300V adaptive voltage suitable for most series and parallel lamp bead tests. During the test the gradual startup mode is adopted the voltage is automatically adapted the current is gradually increased and the lamp beads will not burn and the normal brightness can be achieved in three to five seconds. The positive and negative poles of the lamp bar and lamp bead are connected inversely without burning the lamp bar and lamp bead. -Digital display of real-time voltage output with adjustable voltage the voltage value can be self calibrated. The digital meter adopts green light-emitting tube. 00 indicates short circuit and 300V indicates open circuit. The display voltage of each group of LED light bars of the same LCD TV shall be the same. -Cold and hot isolation never get electric shock. The integrated design of the power cord and the machine box makes it easy to carry when going out. -You can light up the LCD TV screen without removing the screen. (The screen with bad lamp beads is lit as well. The LCD TV is generally divided into several groups in parallel. The voltage can be used to see which group of voltages are different so as to determine which group of LED lamp beads are damaged.) -When testing do not look directly at the lamp bead because of the highlighted version. To avoid eye injury -Precautions: When the positive and negative poles are uncertain please use 19V voltage to detect the positive and negative poles. It is prohibited to use 300V voltage to detect. 300V voltage may cause equipment damage. Short circuit the positive and negative electrodes of the stylus for three seconds to switch between high and low voltages Specifications: -Weight: 254.5G -Name: LED Bead Lamp Bar Tester -Removable screen LED backlight LCD TV maintenance detection lamp bead lamp with lamp plate lamp strip tester lamp lighter -0-300V high brightness removable screen version: -Input voltage: 85-265V -Output voltage: 0-300V power: 18W. -Automatic detection of output voltage and current. It can test LED backlight and lamp beads of any size.
