I am new to electronics and the use of an oscilloscope. I have read several threads about the dangers of floating an o-scope. I own a Rigol DS1052E o-scope. I've noticed that the BNC ground on the two channels are tied together (no resistance), however, there is 4.2k ohms between the channel clips and the earth ground lug.
Is this o-scope floating?
Would it be permissible to probe the AC outlet with this o-scope?
I assume it would be dangerous to do so with an o-scope that is ground referenced (as you might clip the ground lead to the hot wire)?
Is it counter-productive to wear an anti-static wrist strap while working with an o-scope regardless of the type of o-scope?
