• --Use high-speed single-chip microcomputer to do voltage sampling test.
• --And drive LED lights to display voltage to realize the integration of boards and cards and reduce the defect rate (because the current is constant, only the voltage is used) display function).
• --0-300V adaptive voltage, suitable for testing most series and parallel lamp beads.
• --The digital display shows real-time voltage output, with adjustable voltage inside, and the voltage value can be corrected by itself.

Feature:

1. During the test, the gradual start-up method is adopted, the voltage is automatically adapted, the current is gradually increased, and the lamp beads will never be burned, and the normal brightness can be reached after three to five seconds. The positive and negative poles of the light bar and lamp bead are reversed, and the light bar and lamp bead will not be burned.
2. The digital display shows real-time voltage output, with adjustable voltage inside, and the voltage value can be corrected by itself. The digital meter uses a green light-emitting tube, and the display of 00 means a short circuit, and the display of 300V means an open circuit. Each group of LED light bars of the same LCD TV should display the same voltage.
3. Isolated from hot and cold, never get an electric shock. The power cord and machine box are designed in one-piece, which is easy to carry when going out.
4. You can light up the LCD TV screen without dismantling the screen. (The screen with broken lamp beads lights up like the same. LCD TVs are generally divided into several groups connected in parallel. You can see which group has different voltages through the voltage, so as to judge which group of LED lamp beads is damaged).
5. During the test, please do not look directly at the lamp bead due to the bright version. so as not to injure the eyes.

Description:
Product Name: Tester
Input voltage: 85-265VAC
Output voltage: 0-300VDC
Power 18W
Reminder: Automatic detection of output voltage and current. It can test LED backlights and lamp beads of any size. High brightness, no need to dismantle the screen to judge whether the backlight is good or bad.
Tips: When you are not sure about the positive and negative poles, please use 19V voltage to detect the positive and negative poles. It is forbidden to use 300V voltage detection. 300V voltage may cause damage to the device. Short-circuit the positive and negative poles of the capsule pen for three seconds to switch between high and low voltage.
