4.1.2.1 Mass storage

When the USB Mass Storage mode is selected, the machine cannot access the internal memory.
The logger can then no longer be started. In this mode, you can access the memory directly with-
out a driver and copy the stored measurement data to the computer or delete them from the
memory. The measurement data are available as a csv file. The storage location is linked to the
start of the logger, e.g. 31st December 2020 19:11 of the associated files can then be found in the
folder \DATA\20201231\1911\. Single value recordings are always stored in the \HISTORY folder.
Calibration data are stored like logger data but in the folder \CAL_DATA

4.1.2.2 COM interface
