Display data and event data
Display data file size = 8 MB
Event data file size = 8 MB
You can use these figures to calculate the sampling time per file in the same manner as
was used for the case of “only display data” or “only event data.”
You can save multiple files such as those described above to the internal memory or to
an external memory device (the number of files that can be stored is limited by the size
of the internal memory or external memory device).
Calculation Examples of the Sampling Time for a Single File (8 MB)
Examples of the sampling time for a single file (8 MB) are shown below. You cannot
actually set recording conditions so that the sampling time exceeds 31 days. If the
sampling time exceeds 31 days, the file will be divided even if it is not 8 MB in size.
