File names

Logging data file
A file is named with the date (yyyymmdd) of the first data entry.
If data storage is switched to a new memory block when some setting changes and/or disruptions of time in-
dex occurs (if the [Sampling adjustment at time correction] is enabled, when the difference between before and
after time correction is greater than 10 seconds), the currently logging data file is determined and a new file is
created and prefixed with “X”.

Logging data
LOGyyyymmdd
LOG20161101.CSV, XLOG20161101.CSV
[Example]
CAUTION
In the internal memory, if the memory block is switched again on the same day due to setting
changes and/or disruptions of time index, a new file with the same name (i.e. XLOGyyyym-
mdd.csv) is created and two files with the identical name coexist.
However, the former file is overwritten by the latter file when data is transferred to the SD card
and data in the former file will be missing in the SD card.
Download the missing data, if necessary, from the internal memory.

Event data file
A file is named the date (yyyymmdd) of the first data entry.
If data storage is switched to a new memory block, a new file is created with the name added with serial num-
bers (_1, _2, ...).
