Is there any reason one would want to switch to Mean mode rather than be in RMS? I was reading the Vamo forum and it seems like some Vamo's can switch and some can't. I got a Vamo V5 last monday and found out the other day that it has both modes and can switch between them by holding the "-" button for like 10-15 seconds. From my understanding, Mean mode will have a vast range of power it will output even when placed at a low power? So say I have it set to 3.5V, at any point it could be putting out anywhere from 0V to 7V? Or is it only 0V, 3.5V, and 7V? Or do I have this all wrong? But again why would anyone want to put it in mean mode?
