Description
You can illuminate the LCD TV screen without disassembling 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).Specifications:Plug: US Plug / EU Plug (Optional)Input voltage: 85-265V (international)Output voltage: 0-300V, power 25WSize: approx. 100 x 60 x 30mm / 3.9 x 2.4 x 1.2inMaterial: ABSWeight: approx. 138 gProduct use: Widely used in the repair and inspection of LCD TVs and monitors.Package Iist:1 x SFD290 LED Tester2 x Watch hand Note:When testing, because it is a high-bright version, do not look directly at the lamp bead to avoid eye damage.
Features
Use STM8 high-speed single-chip microcomputer to do voltage sampling test, and drive LED light to display voltage, realize board integration, reduce the defect rate (because the current is constant, there is only voltage display function).
0-300V adaptive voltage, suitable for most series and parallel lamp bead test. During the test, the progressive start mode is adopted, the voltage is automatically adapted, and the current is gradually increased, so the lamp bead will never be burned, an
The digital display shows the real-time voltage output with an adjustable voltage inside, and the voltage value can be self-corrected. The digital meter uses a green light-emitting tube. When it is displayed as 00, it indicates a short circuit, and when
Cold and heat isolation, no electric shock. The power cord and the case are designed in one piece, which is easy to carry out.
The brightness is higher than the market's similar highlight version of 30%! Can test any size LED backlight and lamp bead.
