Item Type: Light Bar Light Bead Tester
Material: ABS
Output Voltage: DC0-300V
Output Current: 30 or 50mA
Power: 24W
How to Use:
1. Plug in the power supply, wait until the voltage rises to more than 300V stable, you can test normally.
2. Test with soft start mode, the current slowly from small to large until the stable constant current, voltage since the appropriate, the LED under test will slowly from slightly bright to high brightness.
3. Test regardless of a single bead, the string will not burn, such as can not determine the positive and negative light source under test, 5 beads below the string connected to the reverse time should not be too long, the shorter the contact time, the safer.
4. Open circuit protection: when the output is open circuit, a short time touch the output meter pen will not have the electric shock problem, but do not touch the output of the meter pen for a long time with both hands at the same time, to prevent the current from increasing when you cause injury.
