This is a very good video I love when people go back to basics like this because it is easy to overlook these things when troubleshooting. You must know how your particular meter works too. For instance, the meter I use for work and others have certain limitations you need to know. My meter will read continuity with the tone on, but in that setting, it only reads up to a certain resistance if I turn the tone off, though resistances much higher can be read.
What a great way to start a Saturday. Great video Mike, direct and to the point. And may I add that a cheap set of leads can cause unreliable readings. A good set of leads is important for correct diagnostics.
Thank you. I learned to use a multimeter just by using it and know it often confused me. Until you showed 55volt reading I had no idea what would cause. Great insight into what people commonly fail to understand and then correcting it!
Sounds like part 1 of a Multimeter mini series (the pilot episode 🤣). The morning you woke up and said, "🤬 it! I'm going to make HVAC videos," was a gift from Creation. What's next? Resistance, continuity, frequency, or amperage? Regardless of the order, looking forward to more valuable context with high quality content. (not a paid actor)🤷🏽♂️
Advanced electricians only: Pause the video at 4:32. What happens if you try to "reconnect" the ground wire in the plug that's been mutilated by taking it to the workbench and wiring the ground wire to the neutral wire?, since ground and neutral are connected anyway in the panel. Bonus points if you label each V, A, and Ω at the worthwhile nodes in both on and off states.
If the DVM "didn't" measure the potential difference between the red probe and black probe, what would it be called since its not measuring the potential difference in voltage?
2:50 sorry you are measuring a current, when measuring Voltage. If there is no potential (or the potential is to low for your DMM, even over a switch (there will be a resistant of a milli ohm or lower) then the no current. If you are measuring amps (with out a clamp) than you are measuring Voltage…. 5:27 Both points have the same reference! The Starpoint of the transformer, the are just using different ways. First L to N, second is L to PE.
First off, not everyone goes to a proper school. Second, when I say, "multimeter tutorials", I'm talking about UA-cam. Third, I have spent my entire career taking guys under my wing when they come straight out of trade school and I don't think one of them truly understood any of this, or at best, vaguely recalled that lesson. You don't have to look any further than the other comments in this very video to see a comment along the lines of, "I remember this from trade school, but I didn't get it until now". For most of these guys, "proper school" is like drinking out of a firehose. It's overwhelming. Half of these schools are just money mills anyway. Say what you want, but most of what proper schools teach from day one, it leads to them having to learn it again day one in the field with me.

Excellent point about knowing your meter That's true. I'll pin this to the top of comments so everyone can see it.
Thanks for the comment.
I almost skipped this video, thinking there was nothing he could probably say new to me; I am glad, I watched and learnt something new.

Very very true!
Cheap probes? I don't trust those cheap ones. Best to but some cat 3 rated probes
Great video Mike. Informative, easy to understand, good editing, and great audio. Everything you want in a UA-cam video.
Thank you brother.

Insanely good video. The concepts of potential difference & reference point are red pills that set technicians apart.
Great video Mike. Thank you for the knowledge.
Very good facts pointed out when using a multimeter to take voltage measurements. Thank you!
Welcome
Excellent video, thank you for sharing such informative information.

Excellent! You just gained a new subscriber after that explanation.
Thanks and welcome
Excellent video - Thank you
You're welcome b
Good info ... Thx Sir
Thank you.
Excellent video
love your videos Mike
Thank you!
Good info.
Thx
This is the kind of explanation that you want to hear as a beginner thank you very much
Thank for this very important content Mike...meters and I never got along at the beginning of trade school 😂
Thanks Jersey Mike
I was a field tech with ATT a lot of guys i worked with didn't know basic electricity or how to use a meter.
Good video

You can't talk to beginners like this.
@ That’s just ohms law….
@zoom_h2625 Yes. I'm aware of that. Thank you.
Learn about the FLOW of electricity BEFORE attempting to use a multimeter.
here's a thought. unless you understand electricity and how it works the best meter in the world is useless.
Doesn't get any more true than that.
I cant wait for the day these videos aren't in another language to me. 😂 I have a lot to learn
Fr 💀
Me too. Lol. You'll never know it all.
Stop with the "all this stuff they don't tell you" type of cleverness. In a proper school you learn all this from day one.

Mul-tee meter
...where you live. Not where he lives.
Irrelevant thing to point out my dude.
You're not yourself if you haven't had your cocktail...😊
