Hantek HT20COP probe safe to use or not?

Pappy19

I brought the PicoScope 2204a recently that has the +/- 20v max voltage input. The HT20COP secondary ignition coil probe has a 10:1 built in attenuator. 
some direct injection engine secondary coils can output up to 40kV even with a 20:1 attenuator added into the line I can potentially still damage this 20v max scope? 
Voltage max protection spec is 100v but I’d rather not use a cop probe if there’s any risk. I have the hantek HT25 ignition lead clamp pickup also that has its own ground clamp. Maybe that be safer to use. Thanks very much if anyone can point me in the right direction if I wanna use this in an automotive application. Maybe il just stick to 20:1 attenuated primary voltage patterns. I assumed a secondary COP probe touching a coil only picks up a waveform pattern until I found out it’s attenuated. I guess it just comes down to myself not knowing much about scopes in general

    Hi,

    I wouldn't do it, unless you can confirm what those probes do (I didnt see anything useful in the one-page manual that I found).

    The 2204A is not an automotive 'scope, I doubt it has any isolation. It would be good to directly talk to Picotech, they specialise in automotive testing so they would recommend what you need.

    If you're intent on using your own combination, then it's probably worth using a cheap almost throwaway laptop, or getting a cheap scope that isn't attached to a PC, rather than risk damaging a more expensive computer.
