Hello I'm trying to find a operators manual for a pico 3424. never really used one of these scopes before. The job I'm in now has one but no manual on how to use it. and what it can be used for exactly. I would like to use it to check voltages and amps on some of the devices I working on like power supplies and motors. does anyone know if the pico website has a date base where I can download them . I did not see one there before I came here.
