Hello Ben, Thank you so very much for responding to this thread with a plethora of information about the COP probe and secondary ignition probe inverted configurations. I had indeed seen the inverted configuration for the secondary ignition probe. But being the rookie Picoscope user that I am, since...

Thank you volrem and Martyn for your very helpful responses. I had reviewed the factory-provided inverted configuration for the secondary ignition probe, but missed the negative sign in front of the 10000. Had I caught it, I could haved saved some time right off! In response to your question Martyn,...

Well, I had a chance to test my new custom configs, results were "interesting": The expanded range I created worked perfectly, I can see the full extent of the negative firing voltages in the waveform; Using a custom probe configuration to produce an inverted waveform without the use of math channel...

So last night I was able to load version 6.13.6.3829 of the Picoscope software and set up some custom probes for the COP probe that includes a range from -100kV to +100kV for a +-10V input. Basically I just duplicated the factory COP probe config as volrem suggested and added the expanded range, pay...

Use custom probe instead. Use build in probe, make a copy of that and edit to your ranges and invert if needed. This way you can use it live. You have to install older Pico version though because latest is faulty and crashes on probe editing. Thanks very much volrem for the suggestion. That is exac...

Hello John, Would adjusting the scope settings using the lower tool bar as shown here help any! Thanks Technician, I appreciate the reply. Yes, I thought that might be helpful early on, but I read on that those icons refer to setting whether the trigger set pertains to a rising or declining voltage...

Hi How about using Math Channels and invert the channel you want. Speck, Thank you for this excellent suggestion, I had not used the math channels function before as I have not completely read the entire 224 page user guide. So I worked with it this morning and it does indeed invert the waveform fo...

Thank you for helping me out, Martyn & Tom!

Hello, I've been working on verifying the cause of an intermittent misfire on a 2003 Nissan Sentra with 1.8L QG18DE inline 4 cylinder engine (petrol). It has about 90k miles on it, and seems to run OK at idle, however I have noticed an occasional misfire when driving the vehicle on the road. I have ...

I've just run into this same problem with not being able to edit or define any new custom probes with 6.3.14.4038. Would anyone be able to tell me where I can download the latest previous stable version that does not have this issue? I don't see any previous versions available on the Picoauto websit...
