You can if you get a properly rated high-voltage probe.
The standard ones won't do it.
TurboTom:
Only make sure you never accidentally activate AC mode on that channel. The probe utilizes the 1MOhm input resistance of the scope as part of the voltage divider. If this is galvanically isolated by a capacitor, application of a high DC voltage will completely drop across the scope's DC block capacitor which may break down (actually, probably something much less troublesome will happen -- the COSMO semiconductor relay that's intalled to bypass the capacitor will zener break down and limit the voltage across the cap, most likely without any damage). But in general, this may lead to a potentially dangerous situation, especially if the DC block bypass is arranged as an electromechanical relay or a plain old switch in the particular scope in use...

Thank you for your answers.

I just want's to measure 400 volts.
That means when i buy a probe with 10:1 that can handle more than 400volt. Then i get no problem.
I don't know if i should buy this Rigol or a FNIRSI 1014D. But i guess i will buy the Rigol.

I'd buy a fixed 10x probe just to be sure (ie. no little switch to switch to 1x).
Or even a fixed 100x probe, they're much easier to find than 10x probes and usually have a higher voltage rating.
