Multipurpose LED TV Backlight Tester for All LED Lights Repair Output 0-320V

Model: GJ3C Input Voltage:AC 85-265V (International General) Output Voltage: DC 0-320VVoltage Range:0-320V (Adopt soft start mode, the voltage slowly increases.About 4% of the reasonable error!) Main Application: - Output Current:30mA Testing the LED TV backlight without disassemble.Applicable to any size LED TV backlight repairs. Testing of LED stirng, LED panel,COB and integrated LED lights,etc.(DO NOT LOOK DIRECTLY AT THE LIGHT.) Test voltage parameters for various components(diode,triode,stabilivolt,VDR,capacitor,etc).(>21V) - Output Current:1mA Test voltage parameters for various components(diode,triode,stabilivolt,VDR,capacitor,etc).(<21V) Testing of single LED bead,LED stirng,LED panel,COB and integrated LED lights,etc. - Test voltage parameters for DC power(<300V). - According to the voltage to determine open-circuit,short circuit and the number of the light beads in series. - Check for electric leakage. ATTENTIONS: 1. Please disconnect the power of the detected object first.(If you use to test TV backlight,you should make sure the LCD screen is powered on.) 2. Plug in power,it can be used after 5 to 10 seconds to reach 320V.The soft start mode make the backlight getting brighter slowly. 3. Suggest using 1mA except the TV backlight testing. 4. Don’t connect the probes to the LED for a long time if you can’t determine the “+”and “-”. 5. Don’t touch the output terminal of probes for a long time .It’s safe for touch the probes in short time periods.

• LED LCD screen TV backlight problems are getting increasingly common. As we know, slight voltage change can have a big influence on TV function.
• Excellent tool for diagnosing and locating bad LEDs in backlights.
• With help of this tool, you can know the LED LCD screen backlight problem quickly.
• Testing the backlight of LED at any size display the voltage, It can be tested in a long time, and will not damage the lamp beads
• It has high and low current to choose.
