[Noisebridge-discuss] oscilloscopes

[Jeff Keyzer]

Probably the most dangerous thing with regard to using scopes is that  
the ground on scopes isn't usually isolated, so connecting the ground  
terminal of a scope probe to something that is electrically hot can  
cause damage to the thing you are testing, the scope, and/or  
you.  :-)  Always make sure that what you connect the ground terminal  
to is either really ground (shares the same ground as the outlet the  
scope is plugged into) or electrically isolated from the scope (like a  
battery powered circuit with no connections to the outside world).
