Hi, I recognize the specifications of that scope. Our Chinese friends seem to have "borrowed" the specifications (and more besides) from a now obsolete scope we manufacture for the electronics market. Still as the saying goes imitation is the sincerest form of flattery.
The input ranges should be OK for both the current clamp and COP probe but the main issue will be that your scope is not really an automotive scope. It only has 8 bit resolution so when measuring a signal that goes from 0V to say 2V you will only have 128 vertical steps. If the signal is say from 0 to 2.1V then you only end up with about 50 vertical steps as you need to use the 5V range, at this point you start to really struggle with waveforms like ignition.
Here is an ignition waveform at 12 bits:
Here is one at 8 bits:
The situation with the current clamp should be better, the main problem here (apart from resolution) is that you will not be able to filter out any noise as there is no programmable low pass filter. I think you have a fixed 20MHz filter, but again thats more use in electronics than automotive.
In short they will work OK ish and with a bit of care will be fine for diagnosing faults.
