Click the 'export' button for the data file and then repeat for the spectra file and click 'export'. A message 'Exported data file successfully' will appear in the white bar. After the files have been exported the measurements are attached to the file. Multiple exports can be done in the same day however the measurements will still be written to the same date file. The measurements are appended to the same date file, not overwritten.
For example: 10 measurements are exported at 11:00 on 03-15-2017. Then 5 new measurements are taken and exported at 15:00 on 03-15-2017. The 03-15-2017 file now has 15 measurements that are exported in spite of 10 measurements being exported earlier in the day.
