It depends on how much current the suppy is capable of?  Make a 10:1 
resistive divider of 10 1/4w resistors (maybe 100K or 1M). Tapping off at 
1/10 look at it with a scope or 10 meg DVM.
Take the meter or scope probe impedance into consideration.

It may designed for so low current, that anything you do will kill it?
