Note that the data files collected with SDI-12 (standard sensor) do not contain spectral
data and cannot be reprocessed.
1. If necessary, start the software and supply power to the sensor.
2. Go to the Data menu, then select SUNA , then Reprocess Data .
The Reprocessing Dashboard shows.
3. Push Browse to find the package file, the reference file, and the data file. All are
required to reprocess the data.
• "Instrument Package File" is an .xml file that describes the data from the sensor.
• "Calibration File" is for the reference spectrum and the extinction coefficients of
the chemical species. Use the calibration file that matches the time during which
data was collected. Calibration files are stored in the sensor unless the user
erases them.
• "Nitrate Data Files" will show in the dashboard and the user can select some or
all to process. Spectral data, which is recorded in full ASCII, full and reduced
binary, and APF frames, is required to process nitrate data. Use the reduced
binary and APF frames to reprocess data from seawater deployments. Note that
the APF frames only let the user reprocess data that was collected with the
"integration time adjustment" turned off.
4. The user can change the "Output Directory" if necessary.
5. The reprocess operation will be faster if there is no check in the "Graph Results" box.
6. Push Process Selected File(s) .
The software starts to reprocess the data.
7. Open the files on the PC.
5.2.3.1 Nitrate reprocessing details
Settings in "Processing Settings" and the "Temperature & Salinity Correction" areas do
not show until selected by the user. The user can change these settings as necessary to
get better quality data.
