Hi James,
Thanks for the detailed reply.

I’ve figured out the headers of columns – they make sense now.

I did a series of tests tonight, here are my records: https://www.dropbox.com/s/8y3ate7v8xr0nxw/MooshTests.docx?dl=0

The multiple log file problem seems to happen with the 512 MB card, and not with the 64 MB card.

But on the 64 MB card, it works better. The timing of the logging is half of the requested time, which isn’t a big deal, and sometimes not starting logging.

I look forward to the firmware update with the new features, time setting, etc, also true power and power factor measurements, thanks!
