What that DMM Beep Means - A Continuity Mode Tutorial - Workbench Wednesdays

- It might seem silly to spend so much time on such a simple mode. However, I have run across a few posts on the Internet, including the element14 Community where people do not understand continuity mode. Sometimes it is just a lack of experience and sometimes it is a total lack of understanding of what is happening. The biggest mistake, of course, is trying to measure continuity on a powered circuit. That is just a no-go. So in this video, I wanted to show what the meter is actually doing, how it sees different components, and give a couple of real-life examples of how to use it: bit.ly/35fdajY

That's the most interesting series in e14! Keep going!
At last someone that covers this properly. Thanks!
I learned so much from you're videos.
Love your videos. thanks for sharing!
Thank you...perfect 👌
Btw you put the cap on the same line of the breadboard, so it's basically shorted :P
I think that was the point of the question. An "exercise to the reader" as it is commonly called. It does happen though. I know someone who did similar with the 2 sides of a chip
In my outlet the black and white wire on of the romex changes to numbers no beeping. Is that normal or should it say OL?
Why does your DMM interrupts beeping for a while and then continue on beeping?
Nice
I actually have a board with a schematic - but last night I put it in a case and no way gonna get it out again (one of those "when it's in you *really* don't want to take it out jobs). But otherwise I would have had a go at the trace suggestion. Sounded like a good bit of homework.
This was useful (despite the lack of explanation of what the geoffrey a DMM is ;) ) so... when I get numbers instead of a beep.... this is some sort of resistance. The cap stuff was most interesting, caught me out the other day when checking a protoboard I was midway making till I remembered it was probably charging the cap for a moment. Interesting that the small ones wouldn't register though - good to know.
Very informative video. I am not a electronics person so this might be a dumb question, but what would cause positive 3.7V on one side of a SMD capacitor and negative 7.80 V on the other side of it? Is that normal? No other caps read like that on the board. One more dumb question, should one side of a smd resistor ever be connected to ground?
Entirely depends on the circuit.
And a DMM is?
