Inverted scope display (Read 321 times)

liteace Freshman Member Offline Posts: 27	Inverted scope display Mar 30^th, 2012 at 7:26am Hi All, I was having a play today, got here an old 1987 Merc 230, I selected, Ignition > Distrubitor > Secondary (king lead) and got nothing on the screen, it was only when I moved the trigger right down did I get an inverted waveform, is there anywhere I can click to invert the waveform & any idea why it was inverted ?

The true signal is what you're seeing. Most standard ignition scopes invert the signal automatically. Pico gives the true signal and you do as you please with it.
I learned how to read ignition systems on an old Sun machine, so I like it inverted because that's what I'm use to. You can do whatever you like.
That's the beauty of a Pico

This will give you options of ignition set ups It gives a good starting point that you can tweak till you get what you like. HTH Iain

Use the probes that in the channel menu instead. Here's a couple of pics to show you what I mean The only good thing about the presets in the pico menu is the tutorials for each test.
