ok I am new at the forum side so bear with me ...I have been working on vehicles all my live ..but never the electrical side .....i have all of pauls equipment Snap-On triton d10- picoscope7 and testers as well...i am on the premium course as well ... now I would like to learn how to use them so I need the hand on portion ....i have a 03 dodge ram 5.7 hemi and all I would like to do is see a cop wave form for the first time on my computer ...is there anyone out there willing to help me with this issue....lol
Within the pico software - be it pico 6 or pico 7 - there is a tab called guided functions. This will take you by the hand and walk you through the routine of getting waveforms on a variety of actuators, sensors, systems.
It explains shortly the component and shows how to connect your probe. It will also display a typical waveform of a good signal you should expect.
There is also an app available called Picoscope Automotive which you may find helpful getting a headstart on not only Pico but automotive scoping in general.
With regards to your hemi 5.7:
Being a 2 wire coil you can get primary as well as secondary voltage waveform and also primary current waveforms.
If you have a secondary pick up inductive probe/wand connected to the scope you just place it on top or side of the coil where you would get the best picture. You also can put a high tension extension lead between spark plugs and coil and use a capacitive probe on it for a secondary voltage capture.
The primary voltage you'll see when connecting a standard probe to the control wire of the coil, this would be wire pulsed to ground to make the coil fire. *MAKE SURE TO USE AN ATTENUATOR IF NECESSARY*.
Finally with a current clamp around any one of the two wires going to the coil you will obtain a current waveform of the primary current.
If you want to see detail you may start with a time base of 1 milisecond/div for any of three aforementioned captures.
An expert is someone who knows each time more on each time less, until he finally knows absolutely everything about absolutely nothing.
