It doesn’t recover even after that first acquisition.
Here is an additional piece of information I just discovered, my two two SM200C are actually acting differently. The one that I referenced above was running firmware v3.3.1. The other one I have (which I just discovered isn’t showing the uncal issue) is running v5.5.3. Maybe that has something to do with it…
I am going to try to update the firmware on them both, but first I need to get a hold of a windows machine since it doesn’t look like you have a linux firmware updater tool.
