Automotive Oscilloscopes: What you need to know

Alex Muir explains what an oscilloscope is, how it works and how to perform two tests: a relative compression test by measuring current into the starter motor, and a full pressure test using PicoScope's WPS pressure transducer.

I have yet to see such a thorough explaination of scope use in automotive use. Please continue to make more videos!!!! Thank you!!

The fact this video is done in one take with minimal editing is almost therapeutic.

You actually can identify each cylinder with your relative compression test and here's how . Run the initial test, remove one spark plug and repeat the test. You created an obvious deviation in the cylinder you chose and your engines firing order will identify the rest. Great video!

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.

I learnt more about oscilloscopes in this video than anywhere else. Thank you so much

Always impresses me to find such intelligent people on internet.

Came here from the course just to comment how awesome this video was. Well worth the money.

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!

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...

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!

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!

[DukeDave]

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 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.

[rafaelaguilar]

For many years I wondered how those things worked, in 37 minutes you took all my questions away. Great job!!!

[Mequainnt]

I personally appreciate as an automotive service technician wants to know more about this product the oscilloscope. Thank you so much!!!

Nice introductory presentation of oscilloscope usage in automotive diagnostics.

Looking forward to seeing its use in other automotive sub-systems.

[fredsalter]

Simply an outstanding video. In 2020, oscilloscopes are pretty much an absolute necessity.

[andreson]

Without any doubts, the best channel of mechanics. Superb.

[Al-Fiallos]

Wow! I know next to nothing about oscilloscopes but you make it all so clear and comprehensible.
