This device will allow you to test the integrity of a single LED and chain of connected chains up to 100 pieces. Smart algorithms and isolations eliminate both crystal damage when a single cell is connected at a voltage of 300 volts and electric shock.

The built-in voltmeter shows the operating voltage of the LED or a serial crystal line. The value of 0 volts means short circuit and the value of 300 volts shows open circuit. When LED is detected, the built-in microcontroller will raise the current to a safe level and display the operating voltage on the screen. In fact, the tester slightly reduces the rated current through the LED light, so the voltage is less than 0.1-0.2 volts than reality. This, of course, does not affect the idea of the size of the operating voltage, but indicates careful testing of the crystals. Note
When checking, you need to observe the negative-positive polarity, if not sure, you quickly touch about 3 seconds and exchange it, absolutely do not touch for long because if the device is wrong, the device will burn.
