Okay, we're talking about how to quickly test an LED using the multimeter method
I have my multimeter here and I have the two test probes for the
multimeter. I have my negative test probe and my positive test probe and I have my
LED here and what will do is we'll connect the negative lead to the cathode of the
LED which is the shorter leg here and I'll connect the positive lead of the multimeter to the anode of the LED, which is this longer leg here
And just to clarify, I have my negative test probe in the common of the multimeter
and I have my positive test lead under the voltage oms and milliamps for this particular multimeter
here and what I've done is I've gone ahead and I've turned the setting over to the diode
test setting which is this little diode picture here so I switched it from the off position over to the diode test setting and the continuity setting is also the same setting It already set to this position
as we can see here by the arrow indicator on the multimeter and we can see this
number one here showing that the multimeter is currently on but we're not going to
be looking at that. We're going to take our LED. I'm going to take our LED. I'm going to take
the negative test probe and connect it to the shorter leg of the LED, which is the negative lead or the cathode of the LED
And I'm going to take the positive probe of the multimeter and connect it to the longer leg or lead of the LED, which is the anode or positive leg of the LED
I'm going to turn the LED a little bit like this so it's easier to see
the LED turn on when I connect this positive probe to the LED and we can see the
LED turns on I'll disconnect it again and I'll show you me connecting it and it
comes on it's on off and on again
