I am new to oscilloscopes and I haven't had chance to test my scope with a vehicle yet so
I have been playing with the software using the demo traces as I won't get chance to use my scope with a car until I get to my friends garage on Saturday.
Looking at the traces it appears that the traces are as follows
Channel A injector? ( but why only 3 volts ?)
Channel B Amps clamp measuring whatever Channel A is attached to ( using only 1 amp)
Channel C this looks to be an ignition trace but unsure if it's primary or secondary
Channel D looks to be a crank sensor.
Is anyone able to confirm if I'm correct and if not what the traces are?
Also are there any other demo traces I can use to play with the software?
Channel A Port injection voltage (Please add a x10 attenuator & amend voltage to +- 100 V )
Channel B Port injector current (Please select a 30 A current clamp and amend the current to +- 2 A)
Channel C Primary ignition (Please add a x10 attenuator & amend the voltage to +- 400 V)
Channel D Inductive crankshaft sensor
Using Picoscope 6 Automotive you can change the demo signal order and associated engine speed (See below)
Once downloaded and opened, you are presented with the Guided Tests that contain over 150 example waveforms from multiple sensors and actuators.
Please take a look at Actuators>Injectors (gasoline)>Multi-point injection-injection current where the example waveform confirms peak current of such an injector at approx. 634 mA (See below)

Here you can then use multiple features of PS7 that will help familiarize the waveform analysis controls
The PS6 attenuation settings are incorrect in demo mode, hence the injector voltage (Ch A) at 3 V peak. This version would have originally utiilsed a x20 attenuator (3 V x 20 = 60 V) and I agree, this is confusing if you are not aware of attenuation and how to apply to the signal.
PS7 on the other hand displays the injector voltage signal (Ch A) at the correct voltage level along with the correct input ranges and attenuation settings for the remaining channels (See image below)

For anyone new to PicoScope, PS7 is the way to go and will have you up and running very quickly indeed.
Whilst PS7 remains in beta form at present, I can assure you it is stable for diagnostic use and is now my go-to software for capturing data.
I do use PS6 for the missing features such as Masks, Deep Measure and of course the Waveform Library, but with that said I would prefer you start & practice with PS7
