3.3 Storage
Once an SD card is inserted and the SD logging function is set On in the USB menu, data will be logged.
All relevant NMEA received data will be stored, see paragraph 3.6 Parameters for more details.
The storage interval can be selected in the USB menu only (changing interval on touch screen doesn’t
change SD settings).
The wind data is the average, minimum and maximum over interval set in the USB-menu unless an
alarm is active.
When an alarm is active the storage interval will be set to 5s. When the alarm is resolved the original set
interval will be used again.
All other data is the raw or actual data of the moment it is stored.
