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 .
If you are used to test the LED finished lamps, please disconnect the power supply before! Because it is likely to form a loop, resulting in abnormal test!
- Test the capacitance voltage.
- Test the regulator voltage regulator.
- Lamp lamp plate voltage test value.
- Plug in power, it can be used after 3to 5 seconds.
- The soft start mode make the backlight getting brighter slowly.
- No burn out, If you can’t make sure the “+”and “-”, Don’t connect the probes to the LED which be tested for a long time.
- Open Ciruit Protection : Don’t touch the output terminal of probes for a long time .It’s safe for touch the probes in short time periods.
- Double Isolate Design makes our tester safety with high strength and flame retardancy materials.
Single LED light bar backlight testing:
- Make sure the anode and the acthode.
- Connect the probes on the anode and the cathode.
- Light up the Single LED light Bar Backlight.
- Light up the Double LED Light Bar Backlight.
