Not so important with an isolated transformer, but don't forget that the 
ground of each channel (on most scopes) is grounded to earth ground, so you 
can't measure fully rectified AC from the outlet (such as for an 
SSTC)!!  You should be able to, however, use two probes and set the scope 
to to an ch1 + ch2 thing, with one of them inverted and you have a way to 
measure the voltage between any two points no matter the reference (so long 
as you don't exceed the input voltage on each channel!).
