Operation When the CF Card Is Inserted
CF Write (Data Write Timing):
The timing at which data is written to a file (
CF File) on the CF card. Starting
with the second write operation (append), the operation is timed according to the
save interval. The write count is the count at which the file reaches 5 MB when
measuring at the shortest measurement interval. When the count is reached the file
closes, and a new file is created upon the next write operation. You can choose a
file creation mode of Rotary or FullStop mode (see “Data Storage” in section 4.2).
Info (File Information):
Files have numbers and start/stop conditions. You can access this information
using the PC software’s Viewer function.
