LED TV LCD Backlight Tester HWL300 AC 85-265V 18W LED Lamp Bead Lamp Str Tester Maintenance Repair Test Tools EU US Plug

LED Strs Bead Test Tool TV Backlight Lamp Str Tester 0-300V Multurpose Digital Display Measurement Instruments Feature: 1. Use high speed single-ch microcomputer: 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.) 2. 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 brightne 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. 3. 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. 4. 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. 5. LED Strs Beads Test Tool: 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.) Specification: Input voltage: 85-265V Output voltage: 0-300V Power: 18W Shell material: ABS Size: about 104 * 63 * 36mm/4.09*2.48*1.4in Power adapter: EU/US Plug Color: white, black(optional) Ts: Automatic detection of output voltage and current. It can test LED backlight and lamp beads of any size. High brightne, you can judge the backlight without removing the screen When testing, do not look directly at the lamp bead because of the highlighted version. To avoid hurt your eye 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 the positive and negative poles. 300V voltage may cause damage to the equment. Short circuit the pen for three seconds to switch between high and low voltages

Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.
