UM24 UM24C Color Screen Display USB Tester DC Voltmeter Ammeter

Latest smart-fit GJ3C TV LED backlight tester current voltage 0-320V adjustable laptop lamp light detection repair tool. Multipurpose GJ3C LED TV lamp backlight tester with high and low current gear, for LED backlight and components detection.

Features:
1. It's used for inspection and repair of any size TV LED backlight without disassembling the LED.
2. Capacitance withstand voltage can be tested, test range: 0-200v.
3. It can test the voltage regulation value of the Zener diode, test range: 0-200v.
4. The voltage value of the lamp bead board can be tested to determine the quality of the lamp bead.
5. High and low current gear, the output voltage is 0-320V, a new low current gear is added for component detection, when the positive and negative LEDs are not confirmed, the low current gear can be used to test the positive and negative (safer), and then use the high current gear to detect.
6. Safe, smart, accurate, efficient.

Specification:
Input voltage: AC85-265V.
Output voltage: DC0-320V
Output current: 30mA (for TV testing).
Output current: 1mA (for small components).

Usage:
1. Please disconnect the power of the detected object first.(If you use it 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 makes the backlight get 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 to touch the probes in short time periods.
