All you should take a look at LED lights is a digital multimeter with a diode setting. First, join the black and pink take a look at results in the retailers on the entrance of the multimeter. As soon as the leads are related, swap the dial on the entrance of the multimeter clockwise to achieve the diode setting. This setting will both be labeled “diode” or have the diode circuit image, which seems like an arrow representing the cathode and anode. Put the black probe towards the cathode of the LED, which is the shorter prong, and the pink probe towards the longer prong, the anode. When the probes are touching the cathode and anode of the LED, test that the worth on the digital show of the multimeter is 1600 millivolts. If there’s a totally different studying or no studying in any respect, this means that the LED gentle isn’t working correctly. For extra data on testing LED lights, like tips on how to take a look at with a coin cell battery, learn on!
