Hi,
This is a point which doesn´t have much to do with bugs, it´s a hardware thing.
When i remember it right, in the first FW update a 500µV Resolution was implemented.
"Of course" bandwith-limited and not really a true one.
As I need to measure low currents
Generally, scopes aren´t precisely as dedicated volt-/amperemeters.
If you need to measure dc-currents, you should do it better with an suitable amperemeter.
For example, we must record loadsteps and static values of our converters/inverters.
First one we do of course with a scope, but last we do with a high precision voltage/current/power device.
Because everyone knows that the vertical accuracy of a scope couldn´t reach the precision of a dedicated measure device.
For recording loadsteps the accuracy ist not the most important thing.
Finally we talk about a scope for 1000 bucks….
