I have been doing more logging, and one trick that seems to help in making sure that I have good log files is to be sure to connect to the meter and turn off logging before I pull the SD card.
Previously, I would just pull the SD card out.
What’s the proper procedure? Is disabling logging required? How often does the meter actually write to the SD card?
One other issue is that the internal temperature appears to be off by quite a few degrees on my meter. It is reading about 3-4 degrees C/K low compared to a few other sensors I have.
