8 Saved Data
The D3S ID smartphone application automatically saves data to the phone in
.csv or the industry standard .N42 file format. The .csv file can be opened using
Microsoft Excel and the .N42 file with radiation spectral viewing software.
Over time with regular use the data will build-up and can cause issues if
the phone memory becomes full, therefore the data should be removed
routinely to maintain optimal application performance.
The saved data can be accessed by connecting the phone to a computer via
USB and the phone will appear in the file browser.
The path to the saved data files from the computer is as follows:
This PC\Phone\Android\data\com.kromek.android.D3S_ID\files
The files can also be accessed within the phones file management system,
software capable of opening the specific file types are required to open them.
The path to the saved data files from the phone is as follows:
Files > Device Storage > Android > Data > com.Kromek.android.D3S_ID >

8.1 Search Mode
‘Search Mode’ collects data from the detector in one second bunches and
analyses the last three seconds’ worth of data in a rolling average to detect and
alarm the user of any radiation that may be present.
Whenever ‘Search Mode’ is stopped from within the D3S ID smartphone
application, two files are saved to the location specified above, they are the
‘Detections Log’ file and the ‘Spectra’ file.
The ‘Detections Log’ file contains the search start and stop times plus information
from when the alarm was alarming.
The naming convention for this file is:
‘Date_Time_SerialNumber_DetectionsLog.csv’
The ‘Spectra’ file contains every second of data from the entire search.
