    I've pulled the trigger on this scope:"+LAN+VGA+&_sacat=0&_from=R40

    Have also been reading, and watching videos on how to use a scope.

    In the comments section on one of the vids, a guy mentions that the scope should be grounded for some things; isolated for others. Said it could fry it as you plug it in.

    Since this is my very first scope ever, is there a rule to show how to determine which is which?:confused:

    There could be a lot of info I'm missing.

    If I burn this guy up, right out of the box; the Wife will make sure that I come up missing!;)

    Every scope I have ever used is grounded through the power cable.
    Never connect the ground from the scope or the scope probes to any part of a circuit unless you are absolutely sure that that part of the circuit is also at ground potential

    as far as servicing any item that uses an smps which is not mains isolated-most tvs-crt,lcd and plasma -anything vave related unless the supply is isolated you must use an isolation transformer to power the device you are working on or you will release the magic smoke from your scope and the device under test as well as a loud bang on switch on
