600 VRMS is what it says in my manual and on the scope itself. What you
are referring to is the safety rating on the standard probes that come
with the scope.

The standard probes themselves are rated for 30 V from ground because of
the sleeve, insulation, etc. Although they do have extra plastic molding
so they present no bare metal, to increase user safety at high voltages
you need a probe with better insulation. But the scope itself has
isolation to 600 VRMS. I have one of their safety probes and it has much
nicer insulation on the ground lead and ground clip.

Cheerful regards,

Bob
