ok, i finally worked out how to use the scope function. i plugged my charger in. lol. ok, what i want to know is, what are the max frequency, voltage and current that can flow through it before i kill my 3310? and can i increase the bit so its taller on screen? i cant remember the name for it. but so its bigger on screen vertically. and if its possible to have scope function, would it be possible to add other meter functions, such as ohm meter, or cap meter?
