led leaked currently
This article paper how to use the linearity of index multimeter’s non-linear resistance grade. It states that you should analyze led ledaked currently when measuring semiconductor devices.
The next article also describes the led test of leaked currently. in a strict sense, if you are not professional, don’t try to do it on test led. must use the specialized equipment to test led. if you could not find a specialized equipment, try to use the multimeter.
we are getting multimeter (index multimeter) ready now., When a 10k register gear is change. connect led positive with black point first, then connect negative pole with red point,now the resister value is very small, That means led might be good. then ,we will go to test that led leaked currently. When measuring the led leaked currently, the red test pen should be connected to the positive electrode, and the black one to the negative electrode. again, it’s a small, that means that the leaked current is too large. and we are know that if the current is too large may has a bad effect on led security. so we need to check down the exact circumstances .
