I assume it shows something like "5V == 1A". The dashy symbol thing is just a symbol for DC current.
I've found a nice 5v ac/dc power adapter which i want to use to power up my arduino. now the thing is when i measure V instead of 5 i get 8.~ which may be okay i guess. what bothers me however is that symbol on the output side:
hahaha, okay thanks for that. not sure i grasp exactly what you mean (in particular how would the thing stop at 5v and not drop further?).

No, its the symbol for a DC voltage...
As others have said, that's just the symbol for "DC power"
