How to Use a Multimeter

[@craighellberg4366]

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!

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.

I'm building out a 200 - 600 watt off grid solar system on my KZbin 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.

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. 😀

This is the best Multimeter tutorial so far. This covered all of the questions the other tutorials left out

[@LittleMopeHead]

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.

[@faxmen09]

@@LittleMopeHead Yep, got three of them. 2 were free, first one think I paid $2-3. Worth that.

[@michaelhewesproductions737]

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.

[@th1545]

Thank you! I back probed my window switch and it started working again. Loose wire! Great content

[@PawOfRizzo]

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!

[@anhhuynguyen4969]

Thank you so much man, your explanation is crystal clear and easy to follow!

Educational and Very helpful. Got a clear brief on volts, amps, and ohms (resistance). Also adjusting the accurate amount to get a clear and logical reading. Happy to say that every aspect was simplified for my understanding. Thank you.

[@hectormata449]

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.

[@dave.willard]

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.

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.

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.

[@Science.Buddies]

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.

[@altonlynch5464]

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.

[@michaelbutrim2748]

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.

[@Science.Buddies]

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!

[@sailawaybob]

Great information thank you

[@issackaiser]

Man thank for this video. I learned my multimeter on the old analog needle type back in my school and as some would guess, none of that stick so this is the perfect refresher and plus even taught me what I didn’t know about newer multimeter! That old multimeter had 2 holes so seeing 3 was really confusing 😅

[@alfredolopez-bruce6199]

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?

[@Science.Buddies]

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 KZbin 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.

[@markkoons7488]

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?

[@Science.Buddies]

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.

At 7:51 was the red jumper wire meant to be place one place to the right on the + side, becuase I'm confused on why it's so low below the resistor? Maybe is it couldn't see because off the angle aha.

[@Science.Buddies]

At 7:51 the red jumper wire is plugged into the power bus (the vertical strip on the right next to the red line, with the "+" sign), but it's hard to see because of the camera angle and the wire is bent. Does that clear things up?

Step 4: Touch hot wire with bear finger. Test: Still alive? V> 120 volts Test: Pain? V > 60 Volts. No pain? V < 60 Volts. Step 5: lick finger. Step 6: Touch Hot wire Test: Pain? V> 20 volts
