Details
If the file you specify does not exist on the USB flash drive, this command creates the file.
For options that save more than one item of time information, each item is comma-delimited. For
example, the default format is date, time, and fractional seconds for each reading.
The file extension .csv is appended to the filename if necessary. Any file extension other than .csv
generates an error.
The index column entry in the .csv file starts at 1 for each append operation.
