When you save files, create a folder and then save the files in the folder. Regardless of the remaining
capacity, if you try to save files in the root directory, you may not be able to save files due to file system
restrictions.
Changing the sampling interval, capture destination, number of measuring channels (number of channels
for which the input is not Off), etc. will change the Capture Space and Capture Time on the screen.
If you find that the measurement time exceeds the Capture Time, take one of the following measures:
