New Arrival Screen Led Backlighting LED Tester LCD TV LED backlighti Tester Lamp beads Light board LED light Tester transistor

Description
Digital models, adjustable models: for 0-180V;
1-85 string or strings of various sizes mixed and mixed- SMD light bar,
light board, solder 1W lamp beads special testing and maintenance.
Series and parallel hybrid line can be detected.
Testable 0.5-100W LED light board and lights. In the inner lining is safe voltage 0-80V,
you can be assured;when the voltage is higher than 100V,
advisable to wear when testing repairs.


Primary Function:
This is a and maintenance LED lamp beads.
Specially designed for the majority of electronics enthusiasts.
Solve lamp beads during assembly are not shining bright lights do not cause the problem.
You can quickly identify problems that lamp beads.
Therefore effectively improve maintenance efficiency and save maintenance time,
reduce indirect labor costs.


Use Description

1. The product is suitable for 0.1 to 100 watts (1-90 string) LED light source and
within 100 inch bar use and maintenance of LED backlight LCD TV.



2.1 to 100 inch portable LED monitors backlit LCD TV,
LED board grain SMD LED light source lamp special detector quick inspection,
send a couple of pen lights switch wiring .
LED beads lamp inspection and maintenance essential artifact .
LED, large adjustable voltage.



3. The operation is very convenient and simple,
red pencil and black pencil line the board or lamp beads can detect positive and negative accounts,
normal light, the indicator light.
When they hit two shots, forming pathway lights.

4.Replace the LEDs routing method: connect the new grains pen short lamp,
if it means that the lights installed correctly,
if the plug from the bright lights hairballs can be.

Idea: When transferred to the red zone, do not touch the voltage output.
A.plug in the , to ensure grain safety lamp,
positive and negative before indeterminate please switch to "O".

B.after determining the positive and negative aspects,
if there are no accounts of bright light or too dark light,
it may be because the problem of insufficient ,
then move the file "=" may be the brightness full.


.Testing single lamp beads or series, parallel,
before the number of smaller sources, the switch is the file "O".
The voltage is adjusted to the white areas, the single is 3V,
that light sources have to calculate their supply voltage,
then the voltage regulator at a reasonable place to ,
use process such as brightness is not enough,
then the current file set "I".

Not in use, Pls turn off the main switch!
