NOTICE
To prevent data from being inadvertently lost or deleted from the SD
memory card, take appropriate precautionary measures.
 If you do not want data to be overwritten in the RAM logging area
when the SD memory card is full, set up a device to send a notification
when the SD memory card has little space left.
 Eject the SD memory card only when no data is being written to it,
e.g. by setting a register for "Stop writing".
 In case of a power failure, stop logging data and creating logging files
in time by using an appropriate device.
