Hard to beat that price, especially when one considers how fast it boots up. Viewers should know that necessary accessories like the current probe, capacitive pickup and 10X probe are extra. I love the much more expensive pico, and it is certainly more versatile and accurate, with greater ability to save and analyze waveforms. But this one would quickly answer many questions that a mechanic would be asking.

Do you ever get any criticisms?
Or do you click the FILE 13 button, when they come in?
Hmmm, maybe I should start leaving criticisms, to see if they come thru or not! Let's give it a try.
Your breath stinks! U- scope? Try regular Scope! It's minty fresh! MRS O will love ya for it!
Hey. I just thought up a commercial jungle! You can have all rights to it! No charge!

Thanks, I have been using scopes for many years and I never realized that you could check a brushed motor in that manner. DUH! Makes perfect sense, rather than me troubleshooting every little connection for resistance/conductance and opens. Then after all that, still no solution until I tear down the motor and find the brush/commutator in shambles.
Thanks again.

Have an 03 Envoy XL with rear AC. The rear blower will not come on when I want it to. Sometimes it will just come on out of the blue if I leave the switch on (at full blast. after driving around for a few minutes Never works anymore at any of the slower speeds (except for a quick burp of air through the vents then stops immediately.

On my car the blower motor is dying. Few love taps gets it going until I hit a bump in the road which turns it back off. It either spins slow on high or not at all. Few more smacks gets it up to full speed but it quits after awhile. Not too fond since it died in Winter time here. But its easy to get at it.

Just make sure your fan motor is not controlled by PWM. I work on heavy trucks that have fan motors controlled by PWM. But if you set them to the highest setting, you should have a 100 percent duty cycle.

Should show what a good motor looks like. Rookies like my brother really struggle with wave forms and how to read and interpret them. Thanks for the great content eric. Ps jeep update lol

also there is an adapter for uScope that allows you to view just the AC portion of the wave so you can really zoom in when necessary.
