Hi. I received my DSO Nano V2 few days ago. Battery was discharged on arrival. So I recharged it fully and started using it. Pretty nice basic little scope.
Then I noticed the battery would go dead over night with the Power switch turned OFF. After searching the forum, I decided to check the battery terminals. They were not shorting out. But the ground wire was hanging on with two strands which eventually broke off (pic attached.) I decided to check current draw with DVM.
DSO Switched Off: 59mA - Why???
DSO Switched On: 190mA
I also checked R27 which is 3.25K.
I also checked U10 pin 1 and 6 and getting some readings both ways, is that normal (pic attached.)
So it seems 59mA is the problem. What should I do now?
