Yes Gents
The bottom line is that these diff probes cost ca £200, just so you can poke around some live DUT - and - at that price if I needed to do that then clearly it would be better to buy a separate standalone battery operated DSO Nano - I bought one couple years back ca £50, ok for poking around a SMPS - it does the job.
I think if I really needed to expose myself and my precious Rigol

then I could power it from my existing standby Battery/inverter system which might give me a days work/ charge overnight. Yes a much derided floating scope but the safety issue seems well over blown here (commercial opinions selling). A knowledgeable Tech worth his salt would know
the risks and precautions. This board is after all for those with some electrical schooling

You could spend 200hrs theory/lab work in a Uni course just to cover all the issues raised. So I now know what I dont know

I'm a city shopping car type not a 1000hp EVcar boy racer. Hi spec hi cost solutions are not my bag.
My Rigol has catapulted me from a prewar Austin 7 to a Toyota Aygo (lovely little mover btw)
