Sorting Files
You can sort the file list in descending order by file name, file type, date, or label.
File Size
The file size varies depending on the data that you are saving.
Check that there is sufficient free space at the storage destination before saving the data.
The approximate file size when waveform data is saved along with logging data is shown
below.
File size = (number of waveform samples) × (logging measurement count) × 4 (bytes)
+ logging data (approx. 100 MB max.)
CSV Data Format
CSV data is saved in the following format.
