Just got my new DSO nano in the last few hours and things look good.
However I ran into a problem when trying to access the card when plugging into a computer. The card needed formatting before it could be used. I thought it a bit odd, but formatted it and everything seemed to be ok.
Was then able to save and load wave forms without much trouble.
However after saving the settings as per the manual “Hold “R/S” Button and press “M” button to save current settings as default.” I was suddenly unable to access the card. Plugging it into the computer again told me I needed to format the card before I could use it.
The DSO is version 1.1 and the firmware version is 2.01.
Any help would be appreciated.
