This video is EXACTLY what I needed. I have the same multi meter. I was able to measure the continuity on all my dryer parts, ruling them out as the problem. I saved myself $235. Thank you so much!
You're welcome!
I watched this video for the same reason to diagnose my dryer. Thank you for a great tutorial!
Straightforward to the point, no nonsense, the way it should be !
Excellent basic tutorial. Now I can finally use my free harbor frieght multimeter that's been sitting on the shelf for over a decade! My cheapo one doesn't have the beeping continuity feature :p
I'm building out a 200 - 600 watt off grid solar system on my TH-cam Vanlife van. Re learning my 12th grade physics, amps x volts = watts, circuts, parallel/series, components, etc. I remember breifly soldering wires when I was 11. But, never even owned a multimeter. I just bought a cheap one and would have blown a fuse. Now I wan't to buy a breadboard, resistors, and LED's and geek out with all of this stuff, and test everything in sight using E=IR formulas like I'm a German kid from Frankfurt. My power windows went down in the van, so I need to isolate that problem, and dive into it all to get hands on & figure it out. Look foward to it! Very, very well explained here. Subscribed.
Thanks! If you are going to buy a breadboard, you may find out breadboard tutorial video helpful: th-cam.com/video/6WReFkfrUIk/w-d-xo.html
This is the best Multimeter tutorial so far. This covered all of the questions the other tutorials left out
I agree. I have that exact multimeter, except the brand is CEN-TECH instead of the DT830L. It doesn't beep, but gives the number on the continuity test.
@@LittleMopeHead Yep, got three of them. 2 were free, first one think I paid $2-3. Worth that.
Thank you! I back probed my window switch and it started working again. Loose wire! Great content
Thanks for sharing your video and knowledge. I’m a retired Systems Engineer first studied Electronics in Lane Tech High School Chicago in 1964/65. Hold an Extra Amateur Radio license a bit of Electronic theory and practical hands on experience involved 🤓 Currently in process of designing and building HO & S scale modular railway. Appreciate your time and efforts.
Excellent Instructional video! Thank you for doing what you do which is lend support to hobbyists, tinkerers, students and future engineers and other STEM fields. What you do is infinitely valuable. On a more specific note your video covered everything and was easy to understand. Viewers can always watch at 1.25 or 1.5 speed if they like but I thought your pace was just right for this material especially considering it’s target audience are mostly beginners and novices. Please keep it up. 😀
Thanks! If you found this video helpful then you might also find our breadboard tutorial video useful: th-cam.com/video/6WReFkfrUIk/w-d-xo.html
Great video. Very easy to follow. I've used a multimeter to test ohms and continuity on cables, and for voltage checks. I've not had to test current on a circuit before, so that is good to see. I also have the thin, needle point probes for use on breadboards, but the wire and alligator clip method is definitely useful when you need a continous connection. Thanks for the vid!
I know this is 4 years ago but it’s very well explained. Thanks.👏😁🇦🇺
Are you giving caie physics p3 exam too?? 😭
Thank you so much man, your explanation is crystal clear and easy to follow!
I was following along with my new multimeter and a battery, and I so nearly connected it before your warning about frying the fuse on Amp mode! Very glad I found your video, it was a bit daunting in length, but man, it was clear, and densely packed with everything I needed to know. Many thanks.
The best I've viewed very well explained without all the showmanship I've seen on others, thank you
Solid approach. Thorough, concise and clear, and professional. You instruct like the Green Berets. That's saying a lot if you know how they roll up poorly equipped and untrained foreign nationals and turn them into skilled tactical combatants in relatively little time...amongst other battlefield roles.
Thank you so much. The video is very helpful.
Excellent tutorial. This video is the best I have seen for a novice.
Thank you mate I learn slot from your video..
Getting back into electric field service. Interview tomorrow! Great refresher, thank you so much 🙏
Very clear. Other videos are confusing.
Starting to catch on to understanding circuits.
Thanks---very clear and concise tutorial!
Another excellent explanation, clear and to the point! thank you
Great and very informative. Thank you for sharing. PB
Great, enjoyed it. I have a MM but other than testing the alternator on my tractor, I had no knowledge of what else it could be used for. Until now, that is. Thank you.
Glad we could help!
Fantastic tutorial instruction on working all the settings on a multimeter.
this was the video I've been looking for, as all the symbols sometimes goof
me up.Now I know how to find the right setting and correct positioning of knob
hands down no doubt about it. thank you
I sure appreciate your video, it certainly helped me find out how to check the resistance on my mower clutch! Thanks!
Good video. Clear speech and concise information.
Ty man, I'm trying to learn electrical for automotive and this makes no sense to me, you're making so much more sense
This was great! Perfect starting course for using multimeters.
this video is so dan good! trust me you saved me as I have my high school practicals tomorrow and when my teacher taught me I was like what the actual heck but now imma kill itttttt
Although I learned how to use the multimeter years ago, the tiny written instructions that came with the meter were very confusing and caused me much trepidation in using it. This beginner’s child like approach to learning the use and function of a multimeter is the way to teach and that leaves no ambiguity on the various testing operations on the meter. For the already know it alls, like me, we can still just wiz through it and use it as a quick review less something was missing in my previous knowledge of multimeters. Thank you so much.
We're glad you found the video helpful!
This was extremely well explained!
OMG... i learned so much in this... as opposed to a lot of other info dumps on this subject i tried before that had no heads or tails
Thanks for the info. Great video.
I DO A LOT OF AUTOMOTIVE WORK IN MY FREETIME BECAUSE I REALLY ENJOY IT, BUT I USUALLY AVOID ELECTRICAL STUFF BECAUSE IT WAS INTIMIDATING. THIS VIDEO WAS CLEAR AND BASIC ENOUGH THAT I FEEL LIKE I LEARNED ENOUGH TO TACKLE SOME OF THAT STUFF WITH CONFIDENCE.
very good video and just what I was looking for. really like the way you presented the subject matter. ty
You are very gifted in knowing how to teach
That's so helpful! Thank you for sharing!
One of the better explanatory videos you will see. Very clear.
The first thing you should always do before taking a measurement with a meter is to verify it is working properly. For low voltage situations, simply measure a battery to confirm the meter sees the voltage. For a house wiring system, go to a known working socket and measure the voltage. The purpose of this is to prevent a false negative measurement. Imagine that a test lead has a broken wire, or the internal fuse is blown on the meter. You could check a wall outlet to see if it is safe to work on and get a zero voltage measurement even if the outlet has voltage on it. This is a very dangerous situation. Even a low voltage situation is troublesome because you will waste time if you have a broken lead.
Thanks för a very informative and instructive video. För me as a novice it was easy to follow because of you pedegogic and easily understandable way of explaining.
Thank you so much.. You're a great teacher.
The best video yet on this product!!
Awesome video...thank you.
And whew---I'm glad English is my first language
This is excellent! Just what I was looking for.
Thank you, science buddy.
This was well done and very helpful. Thanks!
Thanks for this wonderful video. I've been studying electrical theory for a year but haven't done any practical. I got a little multimeter and this video was a great introduction. I used a little nose hair trimmer to experiment on and this video made using the meter very easy to understand.
Glad we could help! If you found this video useful you may also enjoy the breadboard video on our channel.
Thanks, I got hired for Aerospace company who does telemetry. I’m engineering technician and rusty on multi meter and oscilloscope. You help. My popcorn went cold because I took good notes. I washed hands b4 note taking because I put hotsauce on my buttery popcorn.
Hey I have a interview for associate tech engineer coming up what kind of jobs do you do?
Spoken like a real left-brain type 😙 🍿
And remember he’s an aerospace engineer. Lol.
@@richiejohnson is that not most common?
@@jasonvaughan2886 I was a little amused by the dual left brain functions. The engineering mind (which I do not have) places equal value on purity--- data and hygiene. The left brain is compulsion driven. The right brain has no discipline.
1 year in elettronic! Trying the outlet tonight!
Thank You for the abundance of information! decent intro to multimeter
Thank you, so much for this! You've got a subscriber :)
Since in the "can measure the voltage across any one of those components individually" diagram, the pair of batteries show one battery with + top and one with + bottom, I think it would lessen ambiguity to label the container with a + and -, else switch the direction of the one + down battery such that the + is up top with the other battery.
Fantastic tutorial for beginners.
Thank you for showing me this I fixed my dryer
Thank you. It was very helpful.
Very informative and easily understandable 👍👏
Great video! :) thank you

I need some help to know how to use the tekpower digital multimeter looks like the red one you have on the video except this one is black
Perfect ❤️
Thanks a lot mate
How do i remove the covers on the probes -factory installed . Tried pulling , tried twisting no luck .
I appreciate the video. I do want to ask a question. I have purchased the same multimeter yesterday. I bought it to test it on my PCM on my jeep renegade. I just don't know what settings it should be on. Any information will be very helpful. Thanks.
Hi - we're a K-12 STEM education nonprofit so our tutorials are intended for kids using multimeters for science projects. We can't really provide advice on car repair - you might be better off asking this question on an automotive channel or forum. Good luck!
I don't need these instruction but I know a lot of people who do, especially how to test the amps. I've had a lot of friends over the year call me, saying their voltmeter doesn't work after they tried to measure the amps. All I can tell them is that the blew their meter and to call me before you try to check the amps and I'll come over to show them how.
How would check items fuses with that multimeter?
Thank you so much for your demonstration. This sure does help. Now for the test, how do I check a circuit on a stereo amplifier? The cooling fan does work because I had it tested, yet it will not turn on once connected to the circuit board. Thanks again. Also, when checking this, is it with the amplifier plugged in or does it matter?
Hi - unless you have more experience with electronics, we don't recommend tinkering with devices while they are plugged into a wall outlet, as they can have dangerously high voltages present inside. Unfortunately it's hard for us to help with debugging a specific piece of equipment in TH-cam comments, but there are other places online like Reddit or Stackexchange where you might be able to post pictures of the circuit and get help.
Excellent explanation.
Can you use this particular meter to measure body voltage? Thanks
Very interesting. Thank you. I have a cheap-o multimeter that reads only to something like 400 ma. I'm trying to sort out the wiring on a drill press with a good 10 A motor and a new switch. Unfortunately, the previous owner rewired with all red wires. When I plug in the machine I trip the 20A circuit breaker. My guess is that the machine's main switch or the work light is improperly hooked up. Can I jump a 9V battery to the plug and learn what's going on that way without frying the low-end Harbor Freight meter?
Hi - one way to avoid frying the meter is to put a large resistor in series with one of the leads. For example if you put a 1 kilo-ohm resistor in series with the load that is powered by a 9V battery, then at most even if the load is short circuited you would get i = V / R = 9V / 1kOhm = 0.009A or 9mA. The drill press won't run with current that low but it would allow you to test wires if your meter does not have a continuity check feature.
I think for a lot of people they will use the meter to check voltage on a wall outlet to see if it's safe to touch. I would like you to have covered this subject better but the squiggly line reference was enough. Thank you.
For beginners we recommend sticking with battery-powered circuits and avoiding the high voltage from a wall outlet. That can be much more dangerous, so we did not cover it in this video since our videos are primarily aimed at K-12 students.
Hi Ben. I have the same multimeter as you use in your video and have a question about the 1.5V and 9V setting near the top of the selector dial. I notice that the 1.5v has (4.0mA) in parentheses next to it and the 9v has (25mA) in parentheses next to it. I assumed this setting is measuring the amount of charge the battery has. So, I tested a small 9-volt battery on this setting and got a 21mA reading. So far so good. But when I measured the mA in the current section of the meter, I got a 680mA (.68A) reading. Why the difference? Do not both settings measure mA? Am I misunderstanding something? Looking forward to your reply. Thank you.
Hi - we hadn't tested that specific setting and didn't include it in the video since not all multimeters have it. But, after testing it myself, I believe the value in parenthesis is the amount of current the multimeter will attempt to draw from the battery. So for example if you got 25mA from a 9V battery, the battery is still fairly "fresh." If you only got 21mA then the battery is not as new. The difference is that in the battery test mode, the multimeter is using some internal resistance to limit the amount of current drawn from the battery. When you set the multimeter to measure current, the internal resistance is (almost) zero, so you are effectively short-circuiting the battery and letting a very large amount of current flow. That can cause overheating and is not a realistic test condition, so the battery test function lets you test the battery with a more realistic load. I don't think I have any original paper manuals for my model DT830L, and after a quick search I can't find one online - this manual: www.all-sun.com/manual/Dt830_en.pdf is for the 830 series but doesn't list the 830L in the table of models. Section 9 on the battery test function says the display will show the battery's voltage, but it doesn't look like that's the case for this model (impossible for a 9V battery to be 25V, so it looks like it's showing the current). Hope that all makes sense.
@@Science.Buddies Thank you, Ben
How would I test a grounding mat?
Fantastic
