CA-300V LED LCD TV Tester Backlight Tester LED LCD Light Bar Tester

  Three major functions:

1. Can test the capacitor withstand voltage value (completed in 5 seconds)

2. Test the voltage regulator diode voltage (complete in 3 seconds)

3. Can test the voltage value of the lamp bead board

Due to the strong demands of many maintenance masters and major brand after-sales masters, the pre-production LED lamp tester has been revised several times, and the CreatAll eighth-generation LED lighting king CA-300V is launched. Refused to profiteering, low-cost sales (0-300V output, voltage and current power are much higher than similar products, the price is 20% cheaper than similar products). The original lamp and light bar automatic identification function, the lamp bead is tested with low current, the lamp bar is tested with high current, and the high-speed single-chip microcomputer is used for operation switching.

The features are as follows:

1. Using 8-bit high-speed single-chip 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, and the glue is never sealed.

2 Originally recognizes the function of lamp bead and light bar automatically. When testing the lamp bead, the MCU automatically recognizes the start of low current. When testing the light bar, the MCU automatically detects and samples, starts timing, and outputs high current after ten seconds. This function is currently (201609), 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 up to 18W, and the peak power is 24W. The current is larger and the measured lamp bar voltage value is closer to the actual constant current plate operating voltage.

3, 0-300V (error 1%) adaptive voltage, suitable for most series and parallel lamp bead test. During the test, the voltage is automatically adapted, and the lamp bead is never burned. When the lamp bead is tested, the current is low. When the lamp is recognized as a high current, the MCU can reach the normal brightness after ten seconds. The positive and negative poles of the light bar are reversed and the light bar is not burned. If the quality of a single lamp bead is poor, the negative electrode may burn the lamp bead, and the single lamp bead is tested as much as possible.

4, 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.

5, isolated hot and cold, never hit the electricity. The power cord and the box are designed in one piece, which is easy to carry out and comfortable to use.

6, you can not turn off 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 lamp beads are damaged). When the screen is not demolished, please disconnect the LED backlight of the original machine. Other normal boot, let the TV be turned on, and then test to achieve better results.

7. When testing, do not look directly at the lamp bead due to the highlighted version. So as not to hurt your eyes.

Model No: CA-300V
Input Voltage: 85-265V
Output Voltage: 0-300V DC
Item Size: 92 * 58 * 32mm
Item Weight: 135g

- Suitable for single LED beads, LED stirng, LED panel and Integrated optical LED
- Support testing the capacitance voltage and the diode voltage
- No need to disassemble panel to test the LED backlights
- Safe Protection: Double Isolated
- Brun prtection: Voltage and Current Intelligent Adjustment
- Safety design : Slow boost , soft start. Increase the current steadily.

1. Plug in power, it would be cost about 3 to 5 seconds to start
2. The soft start mode make the backlight getting brighter gradually
3. If you can't make sure which is“+”and “-”, then not test for a long time
4. Don’t touch the output terminal of probes for a long time
5. Retardancy materials: Double Isolate design makes tester safety with high strength and flame
6.If the tested LED TV's backlight voltage is 000,that means short circuit,if the voltage is 300,that means open circuit.Every light's voltage of the TV should be same,if it is not,then the LED light bar is mutilated
Package List:
1 * Tester
1 * Pair of Test Probe

Note: For long-term use of the product, do not use this lighting device to charge the charging and discharging equipment (such as: capacitor battery), to prevent the device under test from reverse burning and burning the lighter, thank you.
