Details
If the file you specify does not exist on the USB 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 will be 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
errors.
The index column entry in the .csv file starts at 1 for each append operation.
Examples of valid destination file names:
buffer.saveappend(bufferVar, "/usb1/myData")
buffer.saveappend(bufferVar, "/usb1/myData.csv")
Invalid destination filename examples:
buffer.saveappend(bufferVar, "/usb1/myData.")
— The period is not followed by csv.
buffer.saveappend(bufferVar, "/usb1/myData.txt")
— The only allowed extension is .csv. If .csv is not assigned, it is automatically added
Example 1
buffer.saveappend(MyBuffer, "/usb1/myData.csv")
Append reading and default time information from a buffer named MyBuffer to a file named myData.csv on
the USB flash drive.
