LED TV screen backlighting issues are becoming more and more common. With this product, there is no need to remove the screen when testing LED backlights.
You can easily find the LED strip problem, because you dont need to disassemble the LED TV to test the LED strip, which can save you a lot of time.
This LED light LED backlight tester can find the fault LED on the tape by automatic voltage and current regulation in a few seconds.
If there is a problem with the LED strip, you can replace it or replace the bad LED bead.
Transformer insulation is protected from heat and cold and protects you from electricity, so you can use it with confidence.
Suitable for all series of light panels and light strips, perfect backlight detection and maintenance tools! It is a great tool for every technician.
It can be tested for a long time without damaging the lamp bead.
Remove a single test strip from the plastic container, holding it from the end with no colored pads.
Dip the strip (all 4 colored pads) into the transparent liquid to be tested for 1 second. Depending on pH of sample, color will change almost instantly.
Shake the strip to remove excess liquid.
Match the color of the pads to the pH diagram on the box label to obtain the pH value of the tested liquid.
A pH value of 7 is neutral. A pH value less than 7 is acidic, while a pH reading greater than 7 is alkaline.
How to Interpret Water pH Test Results
The pH value of a particular water sample is obtained by matching the colors of the strips reagent pads after being dipped in the test liquid for approximately 1 second against the pH scale, and noting the corresponding number.
