Hi at all, I recently purchase a DSO Quad from an ebay user.
I notice it work properly (I updated it right now without problem), but it doesn’t power on even with a good level of battery charge.
I can work with it only if the USB plug is connected, not with battery!
It seems to have some problem, maybe with battery charging, but I can always read the value Vbt=+4.18 when I switch on it with USB plug (even with battery disconnected !).
I think it very strange , any idea? Thanks in advance.
