I’m having a similar issue, but when I’m done logging, I connect to the meter, turn off logging, then put it in hibernation mode. THEN I remove it from service and take the SD card out.

My problem the last time I tried to get logs was, it apparently stopped logging 1 day into a 7 day run…it logged for all 7 days (I think), but didn’t record anything and I know for a fact there was data to be measured…it’s like it decided to stop taking measurements, but still log 0’s or whatever…

Looking forward to the new firmware update James said was coming this week…
