multimeter tutorial
Hi Martin, I watched the whole video and thought it might drop few words here for you. Funny thing is that I'm a Computer Engineer myself who have no clue whatsoever on basic electronics (even though I studied all of this back in college). Watching this video reminds me of all the useless teachers at the university who are there just because they have a brilliant curriculum; yet they lack of the very basic teaching skills (i.e. clear and concise language, use of analogies for visualization, etc.). I'm very happy I came across your channel, you're very talented and your videos highly instructive. Keep it up and all the best!!
Please speak you hindi
@@nirajbarnwal7813 you let me learn about some basic skill ,th
Great tutorial, thanks 👍✌
Hi Martin, I liked your video but please explain RMS. I read it up and believe that an updated video explaining the concept of RMS will elevate the value of an already good video. 👍
Ah, so you're a technician
Thanks a million. I learned a lot. If I had a teacher like you at school/college/uni, I would've never skipped a single lesson. Knowing something is one thing, but explaining/teaching it to others, requires a different kind of talent and set of skills. You have them all. 🙏🙏🙏
Just in cause anyone is wondering: there is a small mistake in the video. The AA battery reading is 1.191, not the 1.91 that's read out. The former is reasonable for a somewhat discharged battery, the latter is much more than a single 1.5V battery would deliver. Considering the video is intended for those with less experience, people might get confused, so I thought it's worth pointing out.
I knew absolutely nothing about multimeters before watching your video, but after watching this I'm learning a great deal. This is an excellent introduction not only about multimeters but a basic understanding of electricity as well. Thank you sir for making this video and sharing with the rest of us.
Very nice pesentation. I learned a lot. Thank you so much for your time and presentation. Looking forwared to # 2. Have a Multimeter sitting on the shelf for years but did not know how to use it. Good to have someone like yourself that takes your time to help others. THANKS !
Your video is still helping all kinds of people 8+ years later - Huge thanks for your selfless contribution of valuable time and information! Cheers!!🍻
As a plumbing heating engineer thats using test equipment every other day i find it very interesting how you explain the different procedures.
Excellent video and no other like it on UA-cam.Fascinating.
I rarely comment on the videos I watch on UA-cam, but I am completely new to electronics and I really loved your tutorial. Thanks a lot for this video and this series.
I really appreciate the work you've done.
I really appreciated the time you took and your explanations. Cheers
Bob Van West Thanks for the feedback.
just found your channel, wow,supposed to be cutting grass,I'll mow tomorrow
As an Aussie, multimeters were always strange and daunting units! After watching the video I'm no longer scared to take it out of its drawer!
Your video tutorials are so awesome. So easy to digest, especially for a new egg like me! I've subscribed & will learn more about my multimeter. Thank you!
Steve Franklin My pleasure, thanks for the feedback.
Love how you keep it simple so that virtually anyone can follow...and Understand! Thanks!
I am a trainee electrician, and your video has made the uses of a multimeter crystal clear. Thank you.
Thank you so much! This was just what I needed right now as I'm beginning an electrical wire-man education and really struggling with the text book learning. I love your pace, your voice, & especially your careful attention to detail & safety. I'm not a "moron", but I have a learning style that requires visuals, kinetics, and repetition. Thanks again, and God bless you for the thoughtful teaching.
Having watched your video about multimeter, I told myself "this is exactly the tutorial I need". I will visit your channel to learn more electronic knowledge from you. Thank you very much.
As a real novice that cannot "see" electricity, your instructional lessons/explanations are awesome. Please continue the vids. Any explanations on diagnosing, trouble shooting or mere understanding of how appliances, rotating equipment, house hold or recreational vehicle systems would be greatly appreciated.
Tutorial delivered EXACTLY what it's title promised - clearly delivered, stuck to the basics, never got sidetracked into his clearly much deeper tech expertise. Well done. Now this beginner finally understands what he's been doing blindly with his multimeter for years. It's a good thing to go to sleep a little wiser than I woke up. And proud to see a fellow South African sharing his skills freely. Ubuntu.
An excellent introduction to the multimeter; very enjoyable and informative!
Thank you for the time you've invested in making this very educational video. It's more important for me to learn what to do right, though I admit there will always be room for error no matter how careful one can be. I'm heading on to your next video. I appreciate concise very well articulated explanations. All the best.
i really appreciate your calm manner. This is a topic that can produce anxiety when the instructor is hyped.
You really cover everything well. I have learned much watching. I want more!
THANKS
Love it. Clear and understandable. Thank you!
I have learned more in your 30 minute tutorial than in the six months I have been on the job. Thank you for keeping it simple and willing to share! Oh, AC is more dangerous
Ike Rayford Thanks for the post Ike.
Thanks Ike. That was my guess also.
Very helpful, helped me get back to being familiar with a multimeter again. Good job.
Great video, was clear and easy to understand, looking forward to watching the rest of this series to get a better understanding of how to safely use my multimeter.
I am not adding nothing that it was not been said before, but I saw several tutorials on youtube to learn how to use a multimeter, and after watching all your videos of how to use a multimeter, I think they are the best on youtube. I not only learn the basics but also learn a lot about electricity that I did know nothing about. So very thanks for that. Terrific work. Keep going. I already subscribe your channel and have been watching a lot of your videos (leaving thumbs up one all of them to thank you) :)
This has to be among the best tutorials on multimeters. Thank you for such a detailed and simple explanation. All the BEST.
Very clear and excellent demonstration. Thank you!
Pete Webb My pleasure, thanks for the post.
Thank you from Mustang Oklahoma, USA for the time invested in helping others! Very good information ...
I have just received a multimeter (Christmas 2020) and needed some direction in using it for the first time excellent basic no frills explanation for beginners .Thanks for part 1 I will be watching this a few times over before moving on (I'm a slow learner) to part 2 and beyond.
This was an excellent instructional video. I've always had a hard time trying to work with electricity. I'm a visual learner so dealing with or trying to understand electricity always seemed to elude me. Your instructions and explanations along with some really good analogies made this a really good learning experience. I'll look for the second video when I'm comfortable with what you taught me today. Thanks again, nice job. I appreciate your time and effort.
Now I know a little more about how to use my multimeter sitting on the shelf! Thanks for the basic tutorial!
Excellent video and much appreciated 8 years on from the original series posting - Many thanks!
Excellent. Most comprehensive and well explained tutorial I have seen yet. Thanks so much!
You don't just know your work, you have the fundamentals of being great teacher, it's not just about what someone knows but how that person is able to impart knowledge in such manner that it makes learning easy and a pleasure. Thank you very much.

AC might kill you, DC might kill you but the only certainty is AC/DC will ROCK you!
In all seriousness, thanks for the video. Very helpful.

The best explanation of multimeters I could find on the web!
You have NO IDEA how much this helped me. Thank you Thank you Thank you!!!
30 minutes of my time well spent. Thanks.
Your tutorial video is still helping people in 2020! Thank you.
Just come across this video after buying a hyelec ms8233d as building a boeing cockpit and needed guidance on the led set ups. just want to say thank you, very well explained and very easy to follow, baei lekker manir. dankie baei!
Hi from Cape Town Martin!
Thanks so much for creating the content that you do. I have been a Software Engineer for about 15 years, and am only now starting to venture into the hardware / electronics side of things.
I have watched a number of your videos on my journey of learning electronics, and they are always clear, concise and very informative. I especially like that you put an important emphasis on safety. Way too many cowboys our there making things look quick and easy. I much prefer getting a thorough understanding, including of all risks involved, before diving into an activity.
Anyway, just wanted to give you a quick work of thanks for the work that you do, it is helping me and other beginners across the world a great deal :-)
Cheers
Thank you for the information on this lesson.very clear on the lecture.lots of questions were answered.
Amazing explanation, thank you!
Thank you so much for this precise demonstration. You are up to the point without fuss or music.
I appreciate your efforts indeed.
THE TIME YOU GIVE TO HELP PEOPLE IS MUCH APPRECIATED THANKS MJ ORTON
Your videos are Great! very easy to understand and follow. Thank you!
Rodolfo Varela My pleasure, thanks for the feedback.
your a gifted teacher sir,thank you,your really empowering people,it's a lovely gift to give. ;0)
thanks so much! amazing explanation. I am a mechanical engineer, so appreciated the pressure/volume flow analogies! Spent quite a few years living in SA - great country.
Your are amazing, I came on youtube looking for to start to understand electronics, so I can fix my old record player, you have now got me court I your videos. Thank you. You explain perfectly, I feel the relaxation.
I really do like how you simplify & demonstrate your breaking it down for the common clown like me. L.O.L I wish all others would do the same for making it understandable for the common Joe & talk in laymen terms & bring it down to earth. The problems w/others is they want to sound sophisticated & complicate it. I call this prestige or job insecurity for they have an issue w/an inability to relate w/others.
Thank you SO much for this video. You explain it REALLY well, and now I understand electricity a lot better. Thanks!!
+Wendy S My pleasure, thanks for your post.
I couldn't agree more, just what I needed :)
+Wendy S Hey everyone, the greatest results that ive ever had was with the Gregs Electro Blog (i found it on google) without a doubt the most helpful course i've followed.
AC has more amps that will kill you DC is 12 V
DC voltage can be a wide range of voltages. 12VDC is one voltage that you commonly see but it can go as high as several thousand volts. You can be killed be DC voltage.
I now learning how to use a multimeter and have watched quite a few videos, but so far your tutorial has been the best explained and easiest to follow. Thank you for your hard work. Shout out from Barbados.
Thank you. The fact you mentioned safety first then I instantly subscribed. I prefer honest people who are not just making videos for hits.
EXCELLENT VIDEO!!!!! You are a very very good teacher. Thank You
My pleasure Christopher.
mjlorton Hes right!!,thats why i sub
He is right, you are an excellent teacher! You've answered a lot of my questions without me asking! I just bought this multimeter because I really wanted to know how these things worked. Your video's are just unbelievable!! I really do THANK YOU!
Gonnnna fucking sub at 0.1 ohm

Thanks for this very carefully worded, layman-friendly, well thought-out demonstration + explanation. I have known how to measure my motorcycle battery for years (i.e. what holes to plug what wires in, what setting on the meter, what value to expect), but I didn't know what I was doing. Many people have tried to explain it, also using the water hose analogy, but I never grasped it. Much clearer now. Thanks!
SadBunny My pleasure, thanks for the feedback.
Very good analogy of voltage and current. Great tutorial. Thank you!
Excellent video that clearly explains the basic functions of a multimeter with some great practical demonstrations coupled with a good eye on safe usage. Keep up the good work.
For anybody wondering about the question: DC is almost always more dangerous to workers, not because it's inherently more powerful, but because of the difference in physiological effects between AC and DC. The nice sine wave of AC current, indicating that the current reverses periodically, means that when you become a current path, your muscles will contract when the current nears either maxima, and relax as it approaches 0. That means that whatever you were doing that caused you to become the current path, you can stop doing (drop the wire/tool). With DC, your muscles just contract and that's it. You have to just hope that your life doesn't depend on being able to release something, because that ain't happening. I haven't watched the next video yet but I'd bet that's more or less what is said.
It's much easier to get pulled off if it's AC. Even a woman could do it.
good info! sounds like a good interview question.
50Hz in Australia, pretty sure 60Hz in America. AC alternating from +180 degree / -180 degree of the sine wave at 50/60 times PER SECOND....... AC is always more dangerous. Taking holding on to the conductor out of the equation, it is the pulsing that completely fucks up the human body.
A very simple google search can confirm this, the number of people saying DC is more dangerous is worrying and i hope you aren't all in the electrical trade.
@@kcuhc84 *_Even a woman..._*
Great Scott! I didn't realize people were still using this phrase.
@Nick Cranston In the 20th century, they taught in schools that DC was way more dangerous. What they taught took several weeks to explain, which makes it hard to accept a 3 second contrary explanation.
Voltage = pressure
Current = volume
You're an awsome teacher, no one explained to me this in better way you've done
Thanks!
Extremely well presented! I appreciate the way you simplified this complex subject.
Thank you for this very clear introduction to using the volt meter and electricity. Really appreciate your thoughtful video.
Great tutorial, Thanks!
Keep educating!

He is just propagating for fluke through teaching !
No wrong in educating folks.
Excellent. Thank you for the effort you put into this. The actual explanation of the various aspects of electricity makes the biggest different for newbies.
I will be starting my electro education this fall and I'm feeling more prepared already. Thank you! :)
Great video, Sir. "In essence" you explained everything so well that I found myself agreeing with everything and looking at my own (VERY) limited amateur electronics and wonder "what was I thinking"!!
I also would like to add that after watching your electricity basics video and I'm only 5 minutes in on this one, I have never understood the symbols on a multimeter such as dc and ac but after seeing the straight line on the oscilloscope and putting two and two together I understand them, no more cringing and hoping I don't have it on the wrong setting now, you are very informative sir
justin childress Thanks for the feedback Justin.
Well explained ,,,thank you very much,,,spent with you an excellent time and very very fruitful,,,keep up educating the nulles like me ,,,salute to you Sir ji
Very nicely explained. Thanks

This tutorial really hit the spot for me. Thank you, I learned a lot and enjoyed it.
Brilliant Channel spent 3 days watching before deciding on a Agilent Meter thanks a million
That was a very good demonstration. In essence.
Lol. I didn't get it until I watched a little more of the video.
I would say. In essence

Excellent video, I knew quite quite a few of the things you explained, but it was great to have a refresher course!
Ten years later this video is still helping people! Thank You!
All of you engineering experts giving the uploader flak for being "too informative" need to realize that all the info is there to cover everything. You might have the advantage of a good father figure in your life to teach you these things, or a good school system, but not me. I didn't know shit but thanks to this video I do. It doesn't take an expert to learn this, just as it doesn't take a complete moron to look for this video.
Very true, my father didn't taught me anything, he only put fear and doubt in me for ever wanting to learn things, so videos like that are so awesome to close the gap
Well said! I definitely learned a lot. The basics really do help since I am a novice and just looking to start a new project during this quarantine. Gotta learn something new to keep myself busy! Thanks for the video!
@@Tal.10 heeey sounds like my father, such pity, we could have had fun
@@mustang19ms I hear you buddy, today i try to teach my kids to be the complete opposite, it's the fear of failing that holding us back, but if you want to learn and grow you have to try and many times fall on you'r ass till you get it right, i'm telling them if you didn't fail at least 5 times a day don't talk to me :)
Ikr? I just did a rant at my 20 year-old about how can they not be teaching this stuff in school.. It's more useful than how to bake a cake, yet they still teach that,lol. I have a similar rant I roll out now and then about why they don't teach stock market investing in high school. We need to equip kids for real life imo.
would like to see the set up on how you brighten and dim led
Absolutely brilliant. Thank you so much for this tutorial and the way you have go through it in detail
I'd like to thank you for these videos, yours have been by far the most useful and intelligent I have found so far on a wide range of subjects. Keep up the good work. BTW, if Hollywood ever needs a young John Malcovich for a movie, your a absolute shoe in for the part. Cheers.
This video was AWESOME!!!! THANK YOU!!!! MY answer to your question is DC, because it is DIRECT current, meaning the current is straight through, vs. AC which is alternating current and is like an on/off switch or a high/low switch...? I guess II'll see on the next video! :-)
Thank you for this excellent tutorial ! On another note, what would happen if I measure a DC voltage with my multimeter in AC mode and visa versa? Would I run any risk? Hope you can answer, thanks !
FInally eplained with a simplistic concept! Thank you!
Thanks a lot for the great tutorial. It is easy to follow, simple to understand, and thoroughly practical. Asante Sana from Kenya.
Great Multi-meter for beginners guide....had to install a light didn't want to kill myself, bought a multi-meter and looked for a guide and found you. My multi meter looks nothing like yours aka cheap, your in-depth guide was perfect. Even though my Multi-meter was set up different you explained the differences between them very well and I was able to test a live wall jack without getting crispy (always a +) in the process. Light was installed I survived to make this comment and can check batteries to boot which came in handy this morning. Good work.
don't you just love our South African accents? thanks for the video this is amazing!
I was most surprised by the south African electrical strip! that looks way different than what we got in the 🇺🇸
I bless the rains down on Africaaaaaa!
Your video is brilliant. I have no experience at all, a complete beginner and this is perfect for the likes of me. Great analogy with the hosepipe. Thanks
Excellent video. I have not gotten full use of my meter and your videos are showing me other ways I can use for testing equipment and appliances, etc. Thank you. Dan.
DC Power is more dangerous because it holds you tight, while AC will release you after half frequency time.
The human body has a higher impedance to DC currents than AC, so this means that humans are able to withstand the effects of an electric shock arising from DC exposure much better than when exposed to AC
Alternating current (A.C) is five times more dangerous than Direct current (D.C). The frequency of the alternating current is the main reason for this severe effect on the human body. ... At this frequency, even a small voltage of 25 volts can kill a person.
30:44 "And now I've gone and blown it" :D
Thank you for this video. Very clear explanations, good pacing. Looking forward to learning more about electronics through your videos.
I am so thankful that i've found this Channel!!! It was very difficult for me to understand and i had literally no Motivation to study or read about this Subject. But really, after this Video i am super motivated and want to watch and listen more and more from you!!!
you make it simple and interesting, i also like the Tips you give!
thank you soooo much!!!
Even though it's great information I think an entry level meter would be the three plugged one mate. I personally think you should have done your demo for beginners on one of them
16:29 I thought it shows 1.191 volts, not 1.91 volts?
Thanks for this excellent explanation, finally I am starting to understand electricity and how to measure it.
Ty for such informal advice for such a novice as myself
By FAR, Far the best channel for those who are seeking a thorough insight in all aspects regarding this tool.
Absolutely top drawer stuff, cheers 👍
Entry level? The Fluke 177 costs over £200!

My entry level meter is a 1$ Chinese multimeter

DC power is more dangerous then A.C. because D.C is the direct current and there is no cycle of changing polarities in D.C. thanks
It's a trick question. Both are as dangerous as each other, both can kill.
Yes both can kill i understand but logically D.C is more dangerous because of its continuity. i agreed with ur killing philosophy. thanks.
muhammad muneer ahmad malik the human body has a bit of capacitance, if you know how the to calculate that capacitance into your body's impedance you'll see that for the same effective voltage, your body will have more current with AC going through it than DC.

Think about it. When Tesla and Edison were battling it out Tesla was promoting AC, so Edison went on his tour killing animals with AC, but the science won out proving AC was safer, thus our houses are all run on AC.. DC is more dangerous.
Robert Matthews safer for fires, arcs, and whatnot, but not safer when living things get electrocuted. as i said, human bodies have capacitive properties, so when applied with AC voltage, the effective current is higher in AC than DC.
you can test it your self, or look up people who have tested it on their selves. and if you think that this is crazy, go study AC circuits and Capacitive reactances.
i have used your video to help educate RV people that need some basic information..... well put together all my friends have appreciated this educational video.... unfortunatly a lot of people who get into RVing have no clue between AC and dC ...much less trouble shoot...nicely done
I have always wanted to understand electricity. Your instruction is so helpful. Thank you.
AC can kill you but remember it is not the voltage it is the Amps that can cause death ⚡️⚡️💥💥
I wish there was an easy way to remember this because i always mix amps up with volts ...
DC (Direct Current) is more dangerous than AC (Alternating Current). The reasoning is hidden in their names.
Direct current goes forwards and only forwards.
Alternating current goes forwards and backward, in a sense. It's not 100% continuous.
If you were to grab onto a wire with AC power running through it, it would hurt, your muscles would spasm and you'd let go because the electricity goes back and forth.
If you were to grab onto a wire with DC power running through it, it would hurt, your muscles would spasm and you would not be able to let go because the electricity going through your body overrides to electrical impulses from your brain, and it's continuous. This locks up your muscles and you are unable to let go of the electrical wire.

Graystripe000 you couldn't be more wrong, DC is only 12v, AC is 110V mains, Google it.
Fred Nurke ...It would appear that you had a thought that you wanted to display, though failed rather anticlimactically at making a point out of it. Try again.
Graystripe000 mate, if you're having trouble grasping my simple previous post, then you definitely shouldn't be meddling with live mains. Do yourself a favor and have a read of the following article (engineering.mit.edu/ask/what%E2%80%99s-difference-between-ac-and-dc) or just Google it.
Fred Nurke I'm not having trouble grasping your previous post, I'm having trouble seeing how your post is relevant to mine. I was talking about the physics behind AC and DC (which can be at any voltage, mind you) and why one is more dangerous then the other. You came up, said I was wrong and gave me a couple voltages with no actual point.
Then there's you, coming along and saying I'm wrong while going off on me without really stating WHAT I'm wrong about. I'm not saying you're wrong and I'm right, I'm saying that your point, as it stands now, has little to do with what I was talking about and/or does not have enough context to explain where you were going with it. You merely made a statement and said I was wrong, with very little further explanation of your thoughts. I have an idea of what you might be trying to make a point out of (and that's only because of the website's content, which isn't even something you were talking about yourself), but cannot be 100% sure due to lack of context.
So please, politely shut your mouth and leave or come at me with constructive criticism.
It was an amazing way to explain electricity using mechanical terms.
I being a mechanical engineer, it helped me a lot understand quick.
It was a unique approach.
I followed through with a old fluke 77 great info. Look forward to other clips. Thank you
