- Join Bryan Orr for this HVAC-focused 3D animated video breaking down everything you need to know about using a multimeter. In this Multimeter 101 for HVAC 3D animation, you'll get a back-to-basics overview covering fundamentals, safety precautions, tool selection, the megaohm scale, and measuring volts, ohms, amps, and microfarads.
This animation contains detailed graphics clearly demonstrating how to take measurements in different units and scales, including best practices for testing the functions of your multimeter. Learn how auto-ranging works and why it matters. Understand key electrical principles that will help you accurately interpret your readings and perform diagnostic tests, including wiring the meter leads in series with the flame rod to read microamps on gas furnaces.
Whether you're new to the trade or simply need a quick refresher, this Multimeter 101 video has you covered. Bryan explains core concepts in an easy-to-understand way, along with clear visuals of meters in use. Gain the confidence to safely use these essential diagnostic tools on HVAC equipment in the field.
Take your electrical troubleshooting skills to the next level and set yourself up for success by mastering the multimeter. This is an HVAC training resource to help technicians build competency with metrics and tools that impact system performance and customer satisfaction.

I always love the 3D videos. It's like Saturday mornings, but with Heating and Air cartoons.
Ah yes. Like the old Reboot cartoon.
8:07 I like how it appears to specifically be a screwdriver with a broken tip being used to discharge the capacitor. Even broken tools can still have uses! I'm also a little surprised they actually showed what everyone actually uses to discharge a capacitor instead of using a resistor or dedicated capacitor discharge tool (which would be the "correct" way to do the job, but I don't know a single person that's ever done it that way).
That's because you don't pay for the capacitor when it fails. If you did, you most likely would use a resistor or your voltmeter to discharge it.
Your ability to balance that video and come to question of asking and wanting not matching great video.
This is great; and I love the HVAC School videos - I have gained a lot of helpful knowledge here... but I have to say; discharging a capacitor with a screwdriver is not good practice. If the goal is to promote safety, this should always be done with a multimeter set to the highest voltage setting.
the video ive been waiting for! love the animations and explanation! thank you!
Need a Multimeter 102 and 103 tutorial! This one was very helpful. Encourage everyone to subscribe and ✔️ out their app!
This is the powerfull education and informative way ...thx you a lot Brayn .... I am not Hvac technician but I am interested in and I am planing to be .
Thanks, Merry Christmas and a happy new year
Thanks for the 3D explanation is awesome and easy to understand, thanks again Brian 🙏💯
When using the ohmmeter funciton of your multimeter to check resistance or continuity, a low ohm's reading or audible beep, doesn't necessarily mean that you have a good circuit or good path. It only means that the circuit is complete, but a complete circuit is not necessarily a good circuit or good path. The ohmmeter only uses about 5 volts and a tiny current to check resistance and continuity, so it may be able to carry the tiny current but not a larger one. If you come across a circuit and you test it for resistance or continuity and get a low ohm's reading or hear the beep, and the load (e.g. fan, compressor, contactor, relay) still doesn't work, use a test light or another known good load that draws the about the same amount of amps. If the light bulb or known good load doesn't work, then check the circuit wiring and connections for faults. This could be the result of a loose connection, corroded connection, corroded wiring, or damaged wiring. The wire in the circuit may be made up of 20 thin individual strands wrapped in insulation but it can get damaged where 19 of those thin strands get cut and only 1 thin strand remains. This 1 thin strand will pass the resistance test by giving you a low ohm's reading and also pass the continuity test by making the audible beep, but will not be able to carry the current required for the load in the circuit.
I'm gonna share this with some new guys.
Thank you, you might have just gave me a hint I needed for a practical.
Great lesson on the meter and you explain everything so well, thank you.
Hey what a great video .. by any chance do u sell training videos .? Or any training books?
Thank you for another great video!
Good stuff…thank you sir!
Excellent vids.
. Amped on those rings of flux
As always I like your videos nice 3D shows
wonderful video
We want more 😂👏🏾👏🏾
Thank for information
Thank you
Excelente, muchas gracias.
i like the hopscotch method
Were can we buy this 3d video training set?
Great vid
Can you do dc voltage plz
what does the zero in rush mean ?
awesome
The Leads measure DIFFERENTIAL between both leads.
Please make scotsman ice machine ac 106/126 high evaporator temperature alarm rectification
Probably not gonna happen.
Google the service manual for the model. Everything you need to know is in there.
One bad thing about digital meters especially better ones with high impedance have to be careful when measuring AC voltages. Numerous times while only having one probe touching an energized wire and other lead not connected could receive a reading over 80 volts especially in damp locations.

Good
Megaohm meter.. you mean an insulation resistance tester/meter. What do you mean by a Megaohm meter, what are you testing? Your testing the Insulation of the conductors with a high voltage. looking for leakage. Your testing the Insulation resistance. Where you may be getting confused is one of the original manufactures of this type of meter is called Meggar and they still make some of the best meters today. And its often called a Meggar test because of this. But this is just industry Jargon and incorrect, It is not a Meggar test . Viewers, this test is performed by an Insulation resistance tester. Not a Megaohm meter.
There’s an article on Wikipedia if you need more information on them. Just google “megaohmmeter”.
It's you're not your and it's Megger not Meggar. Check yourself before checking others.
