If anyone wanna learn how to use a multimeter, this is the only video I'd recommend. You even went over and beyond with the cheatsheet, I really appreciate it. Thank you.
I’ve watched numerous videos and most have too much information that’s not needed. This answers the questions in a very simple and straightforward way.
I love how you immediately jump into the content. Everything is relevant. There's no dead time. I don't have to fast forward through irrelevant crap. It's straight to the point. Perfect for my A-D-D
Dude, I couldn't agree more. I also have severe ADHD and this explains everything exactly the way my brain needs to hear and see for me to retain the info. Like you said, the way he didn't do some long intro with tons of irrelevant information, or overexplain shit down to micro details. 😂 Well Done!
well spoken.... I've watched so many videos and left still not understanding how to use a voltmeter but you explained everything in a simple understandable way ... thank you ... I now completely understand how to use this...
I started your content by watching the resistor video. I was blown away at how helpful it was. I subscribed to your channel on that video alone and then watched this one. HOLY COW bro!! Such great content!! Maybe I end up commenting on every video. I don’t know, but so far, with two videos down, I am super impressed with how helpful, concise, and well presented your content is. I have used multi meters before for the VERY basic functions and have even watched a couple of other videos here and there to try and figure out the other features. But this videos is by far the BEST. Thank you for the information and the time it took to put this together. It does not go unnoticed and is very appreciated
You are the first person to identify what "Hfe" stands for. THANX. Been electrical/electronics Engineer and hobbyist for 58 years. Nice video for newbies on using a DMM. I will definitely be forwarding this video to friends that are always asking me how to use a meter. Good Job.
I have been a motor manic since the 70's & I always get a multimeter with dwell in it & this is the first video that has taught me how to use my multimeter fully, thank you kindly for the lesson
I've watched a few of these type videos about multimeter usage. After 36 years as an instrument technician, I can say what is missing is a basic test before using a multimeter. The meter leads must be tested before use. Plug in the leads and short the leads to test continuity on the OHMS setting. Zero resistance verifies the leads are good. Secondly, when testing for voltage use a three point test. First, test a voltage source that is live to verify the meter functions. Now test your target source to verify there is or isn't voltage, then retest the live source. Failure to perform these two simple tests could result in electrocution, or at least getting zapped. A good video!
This was the absolute BEST explaining video I have watched. Extremely easy to understand - even for me that have more or less no clue what-so-ever about electricity. Now I know how to measure electricity for home use. Thank you so much for a very good video !! Respect.
Cheap meters can tell you something, if you know their limitations. I have a nice fluke at woek and at the home shop ,but i got a couple The harbor freight freebies at the house. Sure ,the fluke tells me the outlet has 121 volts ac ,and the harbor freight one says 130. When i turn the power off to replace the outlet ,they both read zero. Not so worried about accuracy with that ,just if its safe being on or off. Still works fine for checking the occasional suspected dead battery for the remote and things like that.
@@MrTheHillfolk I agree. I thought of getting a Fluke but realized for home repairs an el cheapo meter works fine. It only has basic functions with cheap build quality but I only ever use voltage and continuity to check batteries and blown fuses and never found a use for all the other functions. For professionals and electronics enthusiasts a Fluke is worth it for measurement confidence and circuit protection but otherwise these harbour freight meters are awesome.
@@jonfreeman9682to be honest, I'm not that impressed with a fluke, being that I work outside all the time as soon as it gets one raindrop on it, DC volts goes thru the roof. 16v on a 12v system? Nope. Pop the battery out and set it on the trucks defroster for 45 minutes and it'll be fine. It's a real headache and a hassle. Save your money.

For years, I have been looking for a "How To" video on using a Multimeter. Your by far is the B E S T I've seen to date. Thank you for your explanation and your cheat sheet!! 👍🏻
I've been using meters for years and never realized the additional symbols next to a function meant to press the select button. I knew to press the select button for the function I wanted but seeing you do it and pointing it out was a duh moment for me. Never too old to learn something thanks!
I don’t know how long it’s been since I watched a video with such high quality like this one, clear, detailed and straight to the point. Great job, James. Thanks a lot.
Most excellent video. I've been using meters for 35 years and spent a lot of time learning to use them. Wish it only took me 12 minutes to learn how to fully understand all the fetchers
on my momma this is the best multimeter video ive seen. when i was learning years ago i probably went through 20 videos and left them all still hardly understanding any of it (learned through trial and error) glad someone finally put something of high quality out for the new people
Bro, thank you so much, I’m a plumber and have picked up a multi meter to diagnose hot water unit problems, this video is invaluable to help out when buying a multi meter
This was an excellent video for a beginner and I’m not a beginner and I still found it excellent and as a refresher. As I work in the field for industrial process engineering and this was quite helpful. Even saved it to my own playlist for quick reference look up when I need to find it.
Excellent short intro for beginners here. Picky addon here, sometimes written K, kilo is officially k, not K, as you can see on the Fluke. K stands for Kelvin.
Open loop or over limit sometimes used by some professionals, sounds close to the concept that the reading is beyond the limit of what the tester is designed by the manufacturer. So overload in this sense is a different concept. But you are also right
You completely blew my mind. I been trying to teach my self how to use a multimeter for years and I saw this video and I was asking my self what could I possibly learn in 12 minutes. You basically thought me everything I been trying to figure out thank you very much for this very fun and informative video.
One of the best video to practically testing the electronic components with understanding of properly use of electronic meters. Thank you for taking time to do this
6:15 I'm at only half of your video and I must thank you: it is a perfect gem for beginner like me, knowing absolutely nothing. I'll bookmark it. Happy New Year, all the best.
One of the best videos on YT. Very helpful and informative; makes me want more detail from you on the uses and features! You get right to the point so no wasted time. Just really helpful all around. Thank you!
I really appreciate this man. I do not have any background in electronics but I love tinkering with my devices so this video boosts my confidence in investing in a good multimeter.
3:55 STOP! DO NOT USE Continuity function to check if a wire isn't broken! A wire can be damaged and still show good continuity. To check a wire for damage use an Insulation resistance tester! For example Fluke 1507!
awesome. this may be the first of many multimeter videos I've seen that describe with just enough simplicity and repetition to make it clear. thanks james.
I am intimidated by my multimeter but after watching this video I have a better understanding on how I’d use it if not I’ll go back to your video. Thank you for the crash course.
Same here bud I saw your message and left my version too 😂 It's 3 am and I am pretty sure I don't have a multimeter at home and I am a medical student I have no idea why I am watching this with great attention
Thank you for making this cheat sheet, at my job we are supposed to be mechanics with the electrical side taken care of by electricians, but the company does not want to pay one so we have to play electrician. This will help training others in my department greatly!
One of the best informative uploads on this particular topic .. Much appreciated and saved for that inevitable moment where my brain 🧠 decides to not work for some silly reason ha! 🙏🏻
Thank You James, now I know how to use & measure with my high-dollar multimeter I scored @ a yard sale. This is what I would call a down & dirty video on how to use & master your Multimeter in under 13 minutes. No B-S, just information you can use, and be confident in using you miltimeter for an intended purpose as needed. Your a great teacher James.
😊 I watched many videos on how to use a multimeter. Your video is by far the best one I see. Also, you have the attributes and skills of great teachers. Well done. 😊
I am an R&D engineer that has used multimeters extensively and occasionally an o-scope … but that is a whole other kettle of fish. Your tutorial is well done … and thank you for going over some of the most common safety risks. One safety example you might consider adding is discharging a high capacitance capacitor like found in HVAC units with a high resistance resistor (bleeder capacitor). You could highlight the changing capacitance whilst at the same rendering the capacitor safe to handle.
2:05 another reason to use only one hand is that if you touch a live wire, the current goes through your body and that almost instantly triggers the differential switch and saves your life. If you use 2 hands, the current might go from your left hand to your right hand, completing the circuit without current going to earth and therefore the differential switch won't cut off the voltage.
Great video. I’ve been an electrician for 20 years and always thought OL meant ohms not open loop😂. The only other thing I’d add is discharge capacitors even after the power source is disconnected. Many years ago father had one blow up right in his face off a burner circulator.
Thank you so much for your thorough explanation of the multimeter. I've been using multimeters for years and I have always tested for continuity with the ohm setting. I never realized there was a continuity setting. And I always wondered what that symbol meant. And most of the time when I'm thinking I want to check homes. I want you actually check continuity. So thank you once again. Great job!
Nice and easy explanation from you. Im one of the many that has used a multi meter for years without knowing what all the symbols are for. I smashed the sub button bro
Yes that was a good intro to meters. One small thing that may mislead some, on most meters you don't have to put the red lead into the amps socket for small currents, typically 200 or 500mA. You will get a much more sensitive reading in the mA range. If you are a keen DIY car mechanic, invest in one with the frequency and duty cycle functions, very handy for testing sensors like cam, crank position, abs, and some types of airflow sensors
Hey! Just want to let you know this is a good video about learning how to use a multimeter. It just happens that I want to buy one to measure my led lights for my props and I happen to stumble on this video! Keep it up!
Thank you for the Video, i am a Electrician by trade but it never harms to learn or relearn things. I always thought "OL" stands for "Over Load" and not for "Open Loop". We learned it that way back in scool too.
This is a good tutorial on multimeters. Here’s a handy piece of info for anyone with 18-V tools: a fully charged battery without load will most likely measure over 20 Volts over the terminals so use the next higher setting to avoid an error/overload message. P.S. Kilos are definitely represented by a lower case k in the SI system.
I own a few different types and brands of multi meters. Each one has its own advantages. I use my auto range Fluke for most jobs, it’s really the easiest one to diagnose and test with. Having one that gives whole and decimal readings is the best one to have. Testing batteries at my house is the most common task I use the meter for.
Best video on how to use these devices for a beginner. I’ve watched several others and this one is the only one that was thorough enough I could understand everything.
One thing to add on to your explanation for continuity. The multimeter will produce a tone until the resistance between two leads it’s under a certain value. It is up to the technician to determine if that value is acceptable for the application. For example, if you are determining if there’s a short circuit and your DMM beeps and shows a resistance of 200ohms, that is okay if in your application the voltage between two lines is 1VDC. But if the voltage is higher then that could be a problem.
11:15 I still don’t understand why it’s a positive reading when you had the red lead into the wrong port. For this use it’s no big deal other than a negative reading id expect when you don’t Inset the black lead into the com port. What am I missing here?
For those meters that don't have a continuity option, (Cheap harbor Fright) you can also use the resistance setting to check for continuity. While you won't get an audible tone, the subtle change in readings will tell you that you are touching the same wire.
Thankyou James, funny my meter is not digital, just old school simple, still trying to get my head around current & continuity testing, but you shed some light for me, cheers & much appreciated !
When you use a meter in series to measure current, it is good to get in the habit of moving the test lead back to the 'normal" jack as soon as you have made your measurement(s). This helps to prevent accidentally short-circuiting something. With some meters the fuse that protects the internal current shunt from overcurrent is quite expensive. If you are using a "true RMS" meter, be sure to read and understand the manufacturers documentation. Fluke, for example, has a DC blocking capacitor in series with the AC input, so the value you read if there is "AC ripple" "riding" on a DC offset is that of the AC component only. Fluke insists this is correct, but it isn't. The true RMS value must _include_ the DC component. Fluke manuals do tell you how to measure the true RMS that includes the DC (square the AC RMS value, add the square of the DC value and take the square root of the sum). Other meters will directly measure the true RMS that includes the DC. There are tons of inexpensive meters that will display way more digits than can be justified by the voltage reference used in the meter. Lots of resolution can sometimes be useful, even if the absolute accuracy is poor, but you need to understand what is going on.
Very informative video. I've been using a multimeter for a long time, and I still learned some things. One small thing I was curious about. You called the "OL" reading an "Open Loop" reading. I was always led to believe that "OL" stands for "Over Limit." Either way, great video.
Wow, I've always wondered how to use one, ut nvr git one because I had no idea how to use it . Your explanation is just perfect. Thank you. Now i can get one.
Really helpful and really efficient with no silly stuff. Thanks for doing it. If you redo it -- and I don't know why you would because it is so good just as it is -- maybe a demonstration of how to safely discharge a capacitor to avoid a shock?
2:10 that is indeed excellent tip. I had that once happening closing circuit via chest.. If it was not a colleague's quick reaction I am not sure how that would end, but your muscles are blocked by electricity and you can't let go.. I had burned holes in the skin on my fingers that took months to heal. Please remember : safety first always.

No one explains it so clearly as you did. I thank you for helping me understand. Well done.
Yes that was a good intro to meters. One small thing that may mislead some, on most meters you don't have to put the red lead into the amps socket for small currents, typically 200 or 500mA. You will get a much more sensitive reading in the mA range.
If you are a keen DIY car mechanic, invest in one with the frequency and duty cycle functions, very handy for testing sensors like cam, crank position, abs, and some types of airflow sensors
Hey! Just want to let you know this is a good video about learning how to use a multimeter. It just happens that I want to buy one to measure my led lights for my props and I happen to stumble on this video! Keep it up!
Thank you for the Video, i am a Electrician by trade but it never harms to learn or relearn things. I always thought "OL" stands for "Over Load" and not for "Open Loop". We learned it that way back in scool too.
Not only your video is good but the continuity function just blew my mind. Holy shit... it's awesome
This is a good tutorial on multimeters.
Here’s a handy piece of info for anyone with 18-V tools: a fully charged battery without load will most likely measure over 20 Volts over the terminals so use the next higher setting to avoid an error/overload message.
P.S. Kilos are definitely represented by a lower case k in the SI system.
I own a few different types and brands of multi meters. Each one has its own advantages. I use my auto range Fluke for most jobs, it’s really the easiest one to diagnose and test with. Having one that gives whole and decimal readings is the best one to have. Testing batteries at my house is the most common task I use the meter for.
Best video on how to use these devices for a beginner. I’ve watched several others and this one is the only one that was thorough enough I could understand everything.
One thing to add on to your explanation for continuity. The multimeter will produce a tone until the resistance between two leads it’s under a certain value.
It is up to the technician to determine if that value is acceptable for the application. For example, if you are determining if there’s a short circuit and your DMM beeps and shows a resistance of 200ohms, that is okay if in your application the voltage between two lines is 1VDC. But if the voltage is higher then that could be a problem.
Great video! Perfect blend of beginner advice and safety warnings
Best Multimeter tutorial I've found by a mile. Thanks for this!
11:15 I still don’t understand why it’s a positive reading when you had the red lead into the wrong port. For this use it’s no big deal other than a negative reading id expect when you don’t Inset the black lead into the com port. What am I missing here?
Calm, clear and concise delivery of the needed information. Thank you.
Best video on TH-cam this one..just wanted to learn about continuity feature on my new meter but learnt alot.
For those meters that don't have a continuity option, (Cheap harbor Fright) you can also use the resistance setting to check for continuity.
While you won't get an audible tone, the subtle change in readings will tell you that you are touching the same wire.
Concise, precise and straight to the point. Very helpful and decisive knowledge sharing.
Thankyou James, funny my meter is not digital, just old school simple, still trying to get my head around current & continuity testing, but you shed some light for me, cheers & much appreciated !
I have been using multiple meters since the 1970s and I find this to be an excellent video.
When you use a meter in series to measure current, it is good to get in the habit of moving the test lead back to the 'normal" jack as soon as you have made your measurement(s). This helps to prevent accidentally short-circuiting something. With some meters the fuse that protects the internal current shunt from overcurrent is quite expensive.
If you are using a "true RMS" meter, be sure to read and understand the manufacturers documentation. Fluke, for example, has a DC blocking capacitor in series with the AC input, so the value you read if there is "AC ripple" "riding" on a DC offset is that of the AC component only. Fluke insists this is correct, but it isn't. The true RMS value must _include_ the DC component. Fluke manuals do tell you how to measure the true RMS that includes the DC (square the AC RMS value, add the square of the DC value and take the square root of the sum). Other meters will directly measure the true RMS that includes the DC.
There are tons of inexpensive meters that will display way more digits than can be justified by the voltage reference used in the meter. Lots of resolution can sometimes be useful, even if the absolute accuracy is poor, but you need to understand what is going on.
Very informative video. I've been using a multimeter for a long time, and I still learned some things. One small thing I was curious about. You called the "OL" reading an "Open Loop" reading. I was always led to believe that "OL" stands for "Over Limit." Either way, great video.
Wow, I've always wondered how to use one, ut nvr git one because I had no idea how to use it . Your explanation is just perfect. Thank you. Now i can get one.
Really helpful and really efficient with no silly stuff. Thanks for doing it.
If you redo it -- and I don't know why you would because it is so good just as it is -- maybe a demonstration of how to safely discharge a capacitor to avoid a shock?
Thank you sooo much for making a super simple video that answered all the questions I had without telling me a bunch of extra stuff!!
2:10 that is indeed excellent tip. I had that once happening closing circuit via chest.. If it was not a colleague's quick reaction I am not sure how that would end, but your muscles are blocked by electricity and you can't let go.. I had burned holes in the skin on my fingers that took months to heal. Please remember : safety first always.
Good stuff, I use my meter all the time as a DIY guy around the house and car but use only what I know not knowing the full capabilities.
