While trying to view signals on a switching power supply (the type used in computers, but a smaller version) I blew the power supply's fuse twice when I attached the scope's ground alligator clip to what I thought were ground points in the power supply.
I guess the scope's ground is not isolated from the AC power outlet? It's a model GOS-622G from Instek. Is there a safe way to view all the voltages in the power circuit?
