Features:

1, the use of high-speed microcontroller to do voltage sampling test, and drive LED lights to display the voltage (by no means 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 and parallel lamp beads test. When testing, use the progressive start method, the voltage automatically adapts, the current gradually increases, never burn the lamp beads, three to five seconds later it can reach normal brightness. The positive and negative polarity of the light bar and lamp beads are reversed, without burning the light bar and lamp beads.

3, digital display real-time voltage output, with adjustable voltage inside, the voltage value can be self-corrected. The digital meter adopts green light-emitting tube, displaying 00 means short circuit, displaying 300V is open circuit. Each group of LED light bar of the same LCD TV should show the same voltage.

4, hot and cold ground isolation, never touch electricity. The power cord and the box are designed in one, which is convenient to carry when you go out.

5, you can light up the LCD TV screen without removing the screen. (There are bad lamp beads of the same screen lit, LCD TV is generally divided into several groups in parallel, you can see through the voltage to see which group voltage is different, so as to determine which group of LED lamp beads damaged)

6, test, due to the high bright version, please do not look directly at the lamp beads. To avoid injury to the eyes

Note:

Please use 19V voltage to detect positive and negative polarity when you are not sure of the positive and negative polarity, 300V voltage is forbidden, 300V voltage may cause damage to the device, short the capsule pen positive and negative for three seconds to switch between high and low voltage.
