Hello, everyone! Welcome to choose Wangyatian brand products for a long time! Should be paid by a large number of repairers and major brand after-s divisions Liely requested that the previous production of LED lamp tester has been revised several times.Special launch of Wang Yatian GD-9 ninth generation lighting instrument (has been exported to many countries)

Technical highlights:

1, Wang Yatian ninth generation lighting fixture use Proprietary mold The appearance is beautiful and beautiful. It is not a product made from the public shell on the market (there are counterfeit products on the market, the special mold is screwed on, and the counterfeit products are buckled). The integrated design is easy to carry.

2, using high-speed single-ch to do voltage sampling test, and drive LED digital tube display voltage (not the other products on the market using the purchased voltage meter, separate installation) to achieve board integration, reduce the non-performing rate (because the current is constant, only do Voltage display function.) All lines are open, the circuit is simple and clear, and no glue is sealed.

3, High-speed single-ch microcomputer is used to switch between high and low voltage files. The high voltage gear can automatically identify the lamp bead and the light bar. The lamp bead is tested with low current, and the lamp bead is always at 25MA current. After being identified as a light bar, the primary current is 20MA, the secry current is 48MA after seven seconds, and the three-stage current is 75MA after seven seconds. No manual intervention required .

6, Nine generations of highlights : Short-circuit the pen for three seconds, the digital tube will appear horizontal bar flashing, at this time you can switch between high and low voltage files, low-voltage file 0-19V output, can be any lamp bead regardle of positive and negative, the positive and negative poles are connected to the actual measurement Will not burn the lamp beads for 48 hours. This function is currently (2017 06), there is no similar product in the market, the power is three times that of similar products in the market, the long-term working power is 30W, and the peak power is 36W. The current is larger and the measured lamp bar voltage value is closer to the actual constant current plate operating voltage. (The current similar products in the market are only 30MA, the power is not enough, and the high and low voltage files can not be switched. The switching s are much smaller)

4, 0-300V (error 1%) adaptive voltage, suitable for most series and parallel lamp bead test. During the test, the high and low voltage files can automatically adapt to the voltage, do not burn the lamp beads, test the lamp beads for low current, identify the light bar as high current, the single ch starts the secry current after seven seconds, and starts after fourteen seconds. Level current. LightNegative positive and negative poles, no burning light bar .

5, the digital display real-time voltage output, the digital tube uses a red light-emitting tube, the display is 00 is a short circuit, and the display 300V is an open circuit. Each group of LED light bars of the same LCD TV should display the same voltage. If it is different, it can be judged that there is a problem with the light bar. After each group of voltages is the same, connect the positive and negative of each group of light bars to both ends of the test leads, and then observe whether there are dark areas on the screen. (The similar products in the market due to insufficient power, can not directly observe the dark area on the screen through the screen)

6, hot and cold isolation, never electric shock. The power cord and the box are designed in one piece, which is easy to carry out and comfortable to use.

7, you can not disaemble the screen, light up the LCD TV screen. ( The screen with the bad lamp bead is lit up. The LCD TV is generally divided into several groups in parallel. It can be seen by the voltage which group of voltages is different, so as to determine which group of LED beads are damaged. ). When the screen is not demolished, please disconnect the LED backlight of the machine. Other normal boot, let the TV be turned on, and then test to achieve better results.

8 , When testing, do not look directly at the lamp bead due to the highlighted version. So as not to hurt your eyes. The following is the actual test results of our actual test:

Parts List:

Standard package: 1 tester;

Package 2: Tester*1 set: a pair of special t pens

Product measurement chart:

If you want to do something good, you must first sharpen your tools! Masters, stop tangling! time is money! Wang Yatian GD-9 intelligent tester is your best choice!

Maintenance masters, are you still entangled in the backlight backlighting and not knowing whether the light bar is faulty or the motherboard is faulty? Is it a mistake to make a tr to a lamp led to the whole machine? Still not sure which lamp bead is bad and is wasting time? For Wang Yatian's eighth-generation intelligent backlight tester, that's not a problem! 0 to 300V voltage adaptive! The current uses soft start technology! Automatic adjustment in three sections! Light bar fault can be detected without disaembling the screen!

Technical highlights:

1. Using 8-bit high-speed single-ch microcomputer to do voltage sampling test, and driving LED digital tube display voltage (not the other products on the market using purchased voltage meter head, separate installation) to achieve board integration, reducing the defect rate (due to constant current, Only do the voltage display function.) All the lines are open, the circuit is simple and clear, never seal

2, 0-300V adaptive voltage, suitable for most series and parallel lamp bead test. During the test, the progreive start mode is adopted, the voltage is automatically adapted, and the lamp bead is never burned, and the normal brightne can be achieved after three to five seconds. The positive and negative poles of the light bar are reversed and the light bar is not burned. A single lamp bead has a poor quality, and the negative electrode may burn the lamp bead.

3. The digital display shows the real-time voltage output. The digital tube adopts a red light-emitting tube. The display is 00 to indicate a short circuit, and the display 300V is an open circuit. Each group of LED light bars of the same LCD TV should display the same voltage. If it is different, it can be judged that there is a problem with the light bar.

4, cold and hot isolation, never electric shock. The power cord and the box are designed in one piece, which is easy to carry out and comfortable to use.

5, you can turn off the LCD TV screen without disaembling the screen. (The screen with the bad lamp bead is lit up. The LCD TV is generally divided into several groups in parallel. It can be seen by the voltage which group of voltages is different, so as to determine which group of LED lamp beads are damaged). When the screen is not demolished, please disconnect the LED backlight of the machine. Other normal boot, let the TV be turned on, and then test to achieve better results.
