Details
The filename must specify the full path (including /usb1/). If included, the file extension must be set to .csv (if
no file extension is specified, .csv is added).
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.
Examples of valid destination file names:
buffer.save(bufferVar, "/usb1/myData")
buffer.save(bufferVar, "/usb1/myData.csv")
Invalid destination filename examples:
buffer.save(bufferVar, "/usb1/myData.")
— The period is not followed by csv.
buffer.save(bufferVar, "/usb1/myData.txt")
— The only allowed extension is .csv. If .csv is not assigned, it is automatically added.
buffer.save(bufferVar, "/usb1/myData.txt.csv")
— Parameter error: filename must not contain two periods or extensions.
Example 1
buffer.save(MyBuffer, "/usb1/myData.csv")
Save all reading and default time information from a buffer named MyBuffer to a file named myData.csv on
the USB flash drive.
