Saving data logging files
The high speed data logger module temporarily saves the target data of the sampled data logging to the accumulating file on
the inserted SD memory card.
Since the size of an accumulating file becomes larger with time, a file is switched with the specified conditions.
File switching names accumulating file to change it to a save file. (A new accumulating file is created after the file name is
changed.)
It is also possible to save a file with a file name saved in advance when creating a new accumulating file.
The specified information such as date and time can be added to the file name.
Save files can be saved to the SD memory card up to the specified number of files. When the specified number of files
exceeds, the operation to either; delete the oldest file in order or stop module, can be selected.
Ex.
If the upper limit of the number of files is 3, save the data logging file
