I got those test leads. Awesome video

Thanks, not my usual style video but it was fun to make.

Thank you for the testimonial Mike. Your support is appreciated.

Any time!

Interesting gunna look into those was just getting mad yesterday because of all the ground running and stacking lol

Whatever it takes to make the job easier or less frustrating is worth a few extra $$. Is what I say.

Looks pretty cool! Another function you would lose is that now there is all one ground like a snap-on scope, so you cant reference another ground point, eg. a crankshaft sensor.

You can always test other ground points, just use another channel. Example: Ch.a battery + and grounded to battery - Ch.b CKP ground Ch.C engine block Ch.d ECU ground. Now what You have done is a voltage drop test for the ground side from b c and d all referenced to battery negative. My 4423 picoscope my Snap on scope and ATS scopes all work this way and there may be others. Also unless I have a very good reason I would never "reference " 2 different ground points, it can get confusing especially for newer users.

@@CartersDiagnostics I understand you can do that. I was just pointing out that a feature of the 4425A is that each one is grounded alone. The reason you might want to ground at a crankshaft sensor is to see the biased voltage on the variable reluctance type sensor or to see if the noise you are seeing is affecting your signal.

@@advancedleveldiagnostics Agreed 💯 . I answered the next comment down the same way, he was asking about the advantages of not having a common ground. I explained a VR sensor also.😅🤣

Is this just for demo? The 4423 scope is a common ground scope and only one channel needs to be grounded. Your leads are set up for the 4425 which is a floating ground scope where every channel has its own ground.

Yes, the scope in the video is a 4423. I was demonstrating it as a 4425. Good catch. I don't have a 4425 so I just made do with my scope to demo the leads.

@@CartersDiagnostics Awesome! Thank you for the reply. Now it makes sense. Lol! I appreciate the reply.

Nice video. What is the advantage of individual grounds for each channel? I'm still using an old school Modis scope which still gets the job done. Peace.

You can test across components and not worry about the common ground with a 4425 style scope. But a common ground style scope could cause this... Example, a 2 wire sine wave style ckp sensors. If you were to test across both terminals with ch.a and test another component with ch.b while its reference to ground. You could create a no start due to the ckp sensor shorting out to the ground on ch.b . I still use a Modis style scope also, its quick to deploy. But if I really need to go deep the Picoscope comes out!
