the internal memory and the number of saved files.
Up to three measured data files and eight other files
can be saved to the internal memory. If there is not
enough free space, delete files or format the SD
memory card, or use another SD memory card that
has been formatted on the CW500. For details, see
“Recorded Data Operation” in section 5.6.
