Welcome to the store!
1. Check the fault: The LED TV backlight tester can test the LED TV backlight and separately test the TV's constant current board, easily determining the LCD TV fault problem. 2. Voltage test: The LED TV backlight tester with manual stepless preset idle voltage (20-330VDC), intelligent and fully automatic adaptation to the LED light source voltage during testing, no adjustment required. 3. Current test: The LED TV backlight tester can manually and steplessly preset the maximum short-circuit limit current (20-150mA), the current is intelligent and fully automatic during the test. 4. Efficient test: When the output voltage is preset to 20 or lower, the 1mA level current can be used to test the offline voltage parameters of the power supply pins of a variety of ICs, which can easily determine whether the IC is good or bad. 5. Easy to use: The LED lamp tester has a special auxiliary lmA accuracy wide voltage (0-330V) constant current source, allowing you to develop various smart applications on your own. 6. Wide range of applications: The LED TV tester is suitable for forward and reverse voltages for diodes, voltage regulators, transistors, MS tubes, etc., voltage resistance or breakdown voltage for capacitor varistors, TVS transient diodes, etc. up to 330V.
