I took a course in college over electronics and how to properly utilize an oscilloscope, and I believe I learned even more here in the span of about 20 minutes than I did in a whole damn course. Bravo.
So far, the videos produced on this channel have really astonished me, and, as an avid car lover with a decent depth of automotive knowledge, it has already answered questions that no other place has been able to answer for me. And the live presentation of the information is so incredible smooth that it is breath taking. Good job, and, please, keep up the good work!
Thanks this is a good video. I liked it, and for a mechanic I'm impressed you are actually troubleshooting! not part swapping! You blew me away! I was totally surprised when you clearly and actually described how the oscilloscope works. This is a great video. Thank-you. Well done.
I purchased this course, and the alternator video (the one after oscilloscopes) is WOW 😲💣🤯!!! Best explanations ever... 👍👍👍 My recommendation to everyone for this course... I learned in this course so many things about how cars work, that I couldn't in few months researching on the internet...
You’ve done an excellent job explaining how a scope works and how to use it, I haven’t found this on any other channel most times they just use it with very little explanation thank you for this series. You have a new fan!
Maybe you can also learn how to save and check the oscilloscope waveform with the comprehensive diagnostic equipment: ua-cam.com/video/xgJQ8nncl1g/v-deo.html
I don't use oscilloscopes for automotive applications, but this video finally helped me understand what triggering does. No one else has dumbed it down like you have.
Amazingly easy to follow introduction to automotive use of a scope. And not boring either, watching the whole video was fun! Best explanation on the use of the amp clamp ever!
First thing you should have dealt with here was safety. Oscilloscopes generally only deal with small voltages. It’s the probes that condition that voltage. There can be very large voltages in a car that can destroy your probes, your scopes and you.
Greetings, Mr. Alex Muir, I am Divyansh Sharma, and I love your video course. I’m a man who wants to learn about cars and spend my life with them, and this video course is really, for me at least, the bridge to a life of automotive excitement. I love how you go into extreme detail about everything, and explain it with all your heart. It’s really helpful for car enthusiasts like me, who want to go into cars, but know a fraction of what there is to know before you can pop the hood and get to work. I especially love those little bits of humour you include in the middle, they really brightens things up. I admire how you really know what you’re doing, which gives me, and I’m pretty sure everyone else, confidence, that we won’t screw things up when we try to do something as little as change the oil. Since I love your course so much, I ask (in the best way possible): When can I get to see the rest of it? You explaining gearboxes, differentials, and with your amazing 3d graphics, the braking system, the power steering, and suspension. I really admire what you’re doing, which is why I’m so excited to see the rest of your magic. Thank you so much for taking time to read this, and I hope you’ll get back to me soon. Regards, Divyansh Sharma
I never knew how I could apply an oscilloscope to the automotive industry. That was one impressive video. It not only explained how the scope functions but what else it can be used for. Thanks for posting such a great video. Barry
Man I love this course . It's very detailed , well explained , it has great quality. It's really worth it I would say the best 18 € I have ever spent. Looking forward for the upcoming videos ! There is something I would like to ask though, I am unable to find the 3D animations on the website , I don't know about the app because I haven't installed it yet but I would love to have that feature on the website so that I can access it from my laptop. Wish you all the best and keep doing your great job!
You should put the transducer into cylinder 1, and use it as your trigger... Then, you need to know the firing sequence of your pistons. This way, you will always know which is cylinder 1, followed by the firing sequence of the other cylinders (i.e. 1234, or 1324, etc..).
wow nice example showing how a multimeter(voltmeter) really works and how and oscilliscope is different. Ive watched so many videos on oscilliscopes and never was that point really made. Ive heard other electonics channels mention something about votlmetes being an average, but this example makes that really clrear, thank you.
You my friend are an excellent teacher. I have been looking for such a long time on the Internet to find someone who can teach me how to use an oscilloscope. You made it seem so easy. Answered so many questions that I could never find on UA-cam . This is why I've subscribed to our channel. Thank you so much for all the details you presented in this video. 👍 👌
Maybe you can also learn how to save and check the oscilloscope waveform with the comprehensive diagnostic equipment: ua-cam.com/video/xgJQ8nncl1g/v-deo.html
Excellent stuff, especially the comment about knowing what to look for and how it works. Many times I have tortured a student by not giving the answer and asking more questions perhaps the smallest of clues because I know they know the answer and to watch that moment when the light goes on in their brain and they fix the problem on their own. Their confidence is then doubled in their own abilities.
Thinking of get an oscilloscope. For my DIY interest on cars. With the way you demonstrate the use of one. I really will look into it. Thanks for your time on doing a great understanding video. 👍
dunno who is this guy..but apparently he has a state of the art knowledge and plus state of the art ability to explain/ I wonder why this video hasn`t gather millions of views like some others :/
I luv how you analyze the function and the conversion of the scale patterns /voltage you did it in a way that just got through to me set me up on some more research thanks much
I toughly enjoyed this video, having a degree in Automotive Service Technology, we went over basic oscilloscope operation but never delved into anything except electrical theory and a quick check for spark plug wires. Thanks
I commenced using O-Scopes back in the linear days. Since the inception of the digital age and the availability of sensor units, the O-scope is much more valuable across the board. With the correct supporting programs almost anything can be scoped for diagnostic purposes.
The popularity of the Automotive Scopes like the PICO is primarily due to the scopes form factor, in that it is possible to put the scope under hood, connected to signals, route the USB cable through the window, or through the firewall, hook up to a PC and take data while operating the vehicle on the road. This is a very powerful feature especially when trying to diagnose driveline vibration or problems that occur due to vibration, bumps or cornering. The other secondary advantage is in the impressive evolution of the PC laptop/notebook processing power and the ability to integrate date taken from the scope with other PC applications in making reports for the customer. If you look at the evolution of PC based oscilloscopes the form factor has always been the primary advantage and partly why a bench scope replacement has specialized into an automotive scope tool.
awesome video,got 4 ch on my verus edge,only used for volts,like volt meter,now just orderd a amp clamp,and better understand how to use it ,show 4 channels too,see whats happening ,live ,voltage over time was the game changer for me ,as a volt meter ,numbers just change ,not show much,i tried my scope on crank sensor ,and abs wheel senser,spin engine over and spin wheel,watch the volts change over time ,prove sensor ok,learnt back probe too,slide pins in ,your good teacher,with a lot passion for this subject,so teach well,explain new concepts,if they ever release ufo tech,they have to let you do a video on it ,how it levitates ,and moves ,you be good at it
Maybe you can also learn how to save and check the oscilloscope waveform with the comprehensive diagnostic equipment: ua-cam.com/video/xgJQ8nncl1g/v-deo.html
The future of automotive diagnosis. Very informative video. I can see how a younger tech savvy mechanic would easily adapt to this but I can also see how the old school guys will dismiss this. Either way very helpful video.
Excellent video i have hantec coscilloscope connected to PC never really understood how to use it properly your video has made it much easier to understand.Thanks
That final pressure peak that appeared to be lower than the rest was not accompanied by current draw. So it was the engine's inertia facilitating the compression stroke. You can also see it is a somewhat wider/slower peak.
thanks- some basic settings i always got confused is now clear in my mind,thanks Alex. good job ,now i can start using my pico on cars to check signals,injectors -commonrail where high current is drawn, cam sensor,crank sensor,timing ,wow a whole world opens.on todays car forget the meter, check canbus speed,signal well inside the ecu whats happenning . Respect
Check out the relative compression tester from Auto Ditex . It can operate with a current clamp or clipped to the battery . You can also sync it to a cylinder to get the reading to match each cylinder . A quick test is about 15 seconds , with no special training . About $ 300.00 . Diagnose Dan uses it . They also have a two channel scope , sensor simulator and other test items .
Nicely done this video. Thanks for putting it together and sharing it. I am in the process to buy one but didn't know how to use it. Now, this is a start for a DIY on my vehicles.
Alex this is a fantastic class for the use of Oscilloscope and also the use of the Pico. I was looking for a class which was it helpful and detailed on oscilloscope. Hopefully you can make more videos like this on the use of the Oscilloscope Pico on different uses like how to check maf sensor or map and others will be awesome.
Great video. Only thing I'd change or suggest would be to add one more test.... Add the other 3 plugs back into the engine and show how a relative compression test, where we were guessing which spike was cylinder 1, now lines up with the transducer on 1 and makes the chart a bit easier to visualize when we know the firing order.
Historical note: After WWII, many large, multi-engine aircraft had flight engineers who monitored and controlled the engines and other systems to relieve the pilots of those duties. Some of those aircraft, including both military and civilian models, were equipped with an oscilloscope at the flight engineer's station to allow monitoring of the primary coil voltages in each of the two magnetos on each engine. Installation of the instrument, which was called an ignition analyzer, was simplified by the fact that a wire from the primary winding of each magneto was already run to the cockpit magneto switches. These P-leads, as they were called, would be shorted to ground when the associated magneto switch was in the off position, preventing primary current that normally induced spark voltage in the magneto secondary winding. The engine can run on one magneto, but if both P-leads are grounded, the engine ignition is off. In addition to the magneto switches, the P-leads each had a connection to a rotary selector switch if an ignition analyzer was installed. The flight engineer could rotate the switch to connect any one magneto on any engine to the analyzer input. With the engine running, the analyzer screen would display the voltage changes caused by the firing of each spark plug secondary circuit, reflected back into the primary circuit by the varying impedance of the transformer. A higher firing voltage at the spark plug resulted in a higher peak on the display. Successive peaks represented the firing voltage at successive cylinders in the firing order of the engine. Although firing order charts were provided in the analyzer handbook, the engineers in fact memorized the numbers, even when most engines of the period had eighteen, and some had twenty-eight, cylinders. The six piston engines on the B-36 bomber fired a total of 336 spark plugs, so the flight engineer had a lot of waveforms to review. If an abnormality was observed on a waveform, the engineer would select the second magneto (some early 28-cylider engines had four magnetos) and view the impulse corresponding to the same cylinder to confirm the problem. If waveforms from both spark plugs in one cylinder indicated a shorted secondary, the engine would be shut down. Shorted secondaries indicated that the spark plug gap was shorted. If both spark plugs were shorted in one cylinder, then almost surely it was caused by debris from broken valves or piston. and the engine would soon fail completely.
I'm so thankful that as a young novice technician I had a certain instructor when I was working at a subaru dealership and he was a kinda rough around the edges older guy and alot of the techs complained about him and said he was old school and you can't make any money doing things the way he would teach ect but he made sure that we could use and understand the 4 channel scope that was built in to the factory scan tool of that time and I thought it was kinda cool anyway so I really drove into learning how to properly use it and just anything I could do with it and fast forward 10 or 12 years I'm working at a European and exotic car dealership and I found that I was able to make very good money mainly working on electrical problems and electrical diagnostics that most of the guys ran from ... I'd much rather make the same money as the guy next to me and not be filthy at the end of the day lol but seriously if it wasn't for joe the Subaru instructor I wouldn't have been able to find my niche in the dealership and make the money I was able to
..... Well done Mate, Excellent presentation. The glitch in the current waveform at 24:26 is the current clamp moving down the cable, (Vibration from the cranking).
Excellent video for MechaTroniComputer (my invention of technical term 20 yrs ago) using 2/4 channels Oscilloscope for Automotive mechanical engineering diagnosis task. The 'Key-Concept' is the same for all field of human knowledges. You must be Expert in your Own-field before your GENERALISED into Other Layman-field through Transducer/Interpreter/Transformer to understand others. This is called Human-being ! Intelligent-idiot is Norm ! Thanks for your human sharing knowledge so that future technology will keep on developing .
Hey Alex, great stuff going on here. Keep up! Would be really keen on something about mild hybrid systems and how an Integrated Starter Generator (ISG) system works. Maybe Suzuki or Bosch could lend you one of their engines/mild hybrid systems. Many new cars are coming up with those systems and the open market technicians are absolutely unaware of the builds. TIA
That was very interesting to watch, specially the correspondance between the various input signals to give a more complete view about what happens! I as not actually looking for a video about how car works, I was just looking for information about what was specifically different between Automotive Oscilloscopes and other models. I'm still not 100% certain about the differences, but I guess it's about: - Specific probe management to do conversions of current into human readable units - Higher range of input voltage not quite sure if there's anything else? Basically what I'm wondering is if a bench oscilloscope can be used on a car, and if an automotive oscilloscope can be used to do electronic, computer and audio-video repair/diagnostics. And yes, great video :)
Such a well done, and EXTREMELY informative video! been trying to find a video that lays it out like this for a minute now! Thank you very much!!! Keep it up!
Just the information I was looking for! I'm looking into getting a scope but I was curious what the real difference is between this type and the automotive type that has the scanner included. Very helpful video, and came across it by chance.....thank you!!
im ok12 I love a good puzzle problem. I bought a autel mk908 and their 4 channel oscilloscope. About 2500 total but it will more than pay for itself with time
Thank you for the video. I can see the amp clamp and scope being a quicker way to test for compression. In the case that the spark plugs aren't easily accessible. Pressure transducer seems unnecessary since you already have the sparkplugs out. Just use a compression tester. My thoughts anyway
Thanks for this. I think it would be great to take it a bit more advanced. I'm very keen to understand the parameters needed for a good automotive scope, and why. For example, what is bandwidth and what is optimal for automotive, and why; further, what sampe rate capability is best, particularly to achieve a good sample rate at a timescale that works well for automotive use --- ie in the ms no micro or nano second scale. what buffering capability is needed. Explaining these parameters, and what to look for in an automotive scope in a simple accessible way would be magic.

I learnt more about oscilloscopes in this video than anywhere else. Thank you so much
I took a course in college over electronics and how to properly utilize an oscilloscope, and I believe I learned even more here in the span of about 20 minutes than I did in a whole damn course. Bravo.
Check out trained by techs
Me too!!!!! Great video. I like how they don't edit out simple mistakes like not taking the plugs out, etc.......!!! :)
You should really check out scannerdanner channel learned alot..
even me,
This video was excellent. No loud music, plainly spoken, one mechanic speaking to others. I wish all YT would follow his lead.
Paying customer here. Your presentation in these vids, I think, is phrickin' phenomenal.
The fact this video is done in one take with minimal editing is almost therapeutic.
So far, the videos produced on this channel have really astonished me, and, as an avid car lover with a decent depth of automotive knowledge, it has already answered questions that no other place has been able to answer for me.

There can be very large voltages in a car that can destroy your probes, your scopes and you.
you really are a great person ! thank you so much for sharing your knowledge, may god bless you !
For many years I wondered how those things worked, in 37 minutes you took all my questions away. Great job!!!
I personally appreciate as an automotive service technician wants to know more about this product the oscilloscope. Thank you so much!!!
A brilliantly straightforward and easy to understand instructional video. Thank you Alex.
Excellent explanation of how a scope can be used in the field with terrific simplicity
Wow! I know next to nothing about oscilloscopes but you make it all so clear and comprehensible.
Without any doubts, the best channel of mechanics. Superb.

I watch your program so much times that I had to purchase all of them. Love the information and the correct terms and words.
Thank you very much for this very good explanation. So far the best I've seen for automotive oscilloscopes to explain beginners how to use it. Thanks!
Boy! I can't wait to see more diagnostic with oscilloscopes.
Man I love this course . It's very detailed , well explained , it has great quality. It's really worth it I would say the best 18 € I have ever spent. Looking forward for the upcoming videos !

Simply an outstanding video. In 2020, oscilloscopes are pretty much an absolute necessity.
One of the best automotive video I ever watch on UA-cam... You are a PRO......!!!
Sorry Alex... I have only 5 "*****" to grate your video...!!!
Came here from the course just to comment how awesome this video was. Well worth the money.

Nicely explained. You can simulate a compression problem on the relative compression test by slightly loosening up a spark plug.
Learned more than I did in tech school for electrical thanks so much

IMHO it was a major blunder that he didn't do that, or used some other trigger to identify each cylinder on the scope

I'd much rather make the same money as the guy next to me and not be filthy at the end of the day lol but seriously if it wasn't for joe the Subaru instructor I wouldn't have been able to find my niche in the dealership and make the money I was able to
..... Well done Mate, Excellent presentation.
The glitch in the current waveform at 24:26 is the current clamp moving down the cable, (Vibration from the cranking).
Excellent video for MechaTroniComputer (my invention of technical term 20 yrs ago) using 2/4 channels Oscilloscope for Automotive mechanical engineering diagnosis task. The 'Key-Concept' is the same for all field of human knowledges. You must be Expert in your Own-field before your GENERALISED into Other Layman-field through Transducer/Interpreter/Transformer to understand others. This is called Human-being ! Intelligent-idiot is Norm ! Thanks for your human sharing knowledge so that future technology will keep on developing .
Hey Alex, great stuff going on here. Keep up!
Would be really keen on something about mild hybrid systems and how an Integrated Starter Generator (ISG) system works. Maybe Suzuki or Bosch could lend you one of their engines/mild hybrid systems. Many new cars are coming up with those systems and the open market technicians are absolutely unaware of the builds.
TIA
Very Nice, Enjoyed this Video. Love the Informative Visual Presentation & Explanation.
awesome content! This is exactly what I was looking for to learn diagnosing a car
That was very interesting to watch, specially the correspondance between the various input signals to give a more complete view about what happens!
I as not actually looking for a video about how car works, I was just looking for information about what was specifically different between Automotive Oscilloscopes and other models.
I'm still not 100% certain about the differences, but I guess it's about:
- Specific probe management to do conversions of current into human readable units
- Higher range of input voltage
not quite sure if there's anything else?
Basically what I'm wondering is if a bench oscilloscope can be used on a car, and if an automotive oscilloscope can be used to do electronic, computer and audio-video repair/diagnostics.
And yes, great video :)
I liked the way how he explained the details , thank you , You doing A great job 👍
Such a well done, and EXTREMELY informative video! been trying to find a video that lays it out like this for a minute now!
Thank you very much!!! Keep it up!
Brilliant, learned an absolute ton of info here. Very well explained and will be very handy in the future.
I am an electronic engineer ,it was interesting to know how an oscilloscope is useful in garage!.
Do you use an oscilloscope in your line of work?
That was very well done I enjoyed every moment of it thank you.
Just the information I was looking for! I'm looking into getting a scope but I was curious what the real difference is between this type and the automotive type that has the scanner included. Very helpful video, and came across it by chance.....thank you!!
So well explained. And very watchable. Makes me wish I was a mechanic!
im ok12 I love a good puzzle problem. I bought a autel mk908 and their 4 channel oscilloscope. About 2500 total but it will more than pay for itself with time
graet video pico dso one of the best on the market
thank you for explanations. you spent a lot of time and effort to bring that knowledge as more easy to understand. you are awesome
Really fantastic demonstration of the oscilloscope - THANK YOU MUCH 👍👍😁✌️✌️
Excellent video and instruction on the pico scope .
Thank you
Thank you for the video. I can see the amp clamp and scope being a quicker way to test for compression. In the case that the spark plugs aren't easily accessible. Pressure transducer seems unnecessary since you already have the sparkplugs out. Just use a compression tester. My thoughts anyway
This is Great .impressive explanation. Thank you so much
We hope you will publish more videos about different uses of this device and thank you in advance.
Thanks for this. I think it would be great to take it a bit more advanced. I'm very keen to understand the parameters needed for a good automotive scope, and why. For example, what is bandwidth and what is optimal for automotive, and why; further, what sampe rate capability is best, particularly to achieve a good sample rate at a timescale that works well for automotive use --- ie in the ms no micro or nano second scale. what buffering capability is needed. Explaining these parameters, and what to look for in an automotive scope in a simple accessible way would be magic.
Superb demonstration!
Long winded but effective knowledge
Thanks for this video. It’s really interesting to know these little tips.
Great stuff, I have one and this helped a lot. I'm mostly working on motocycles. Now I can tune them with more precision!
Thanks, I learned something here. Will you be making more videos on how to use an Oscope for engine diagnostics?
Outstanding tutorial, kudos to you & keep motorin'!
Great explanation about oscilloscopes.
Tough subject to teach to newbies on the best of days. Good job 👍😁 SUBBED! Thank you ❤
