Processing Data Using SBE Data Processing
1. Convert the .hex (raw data) file (real-time file from SEASAVE or
uploaded from 19plus V2 memory) to a .cnv (engineering units) file in
SBE Data Processing’s Data Conversion module.
2. Once the data is converted: perform further processing (align, filter,
remove bad data, etc.), calculate derived variables, and plot data using
SBE Data Processing’s other modules.
Verifying Contents of Configuration (.con) File
To convert the .hex (raw data) file, you need a .con file, which defines the
instrument – integrated sensors, and channels, serial numbers, and calibration
dates and coefficients for all sensors (C, T, and P as well as auxiliary sensors).
SBE Data Processing (as well as our real-time data acquisition software) uses
the .con file information to interpret and process the raw data. If the .con file
does not match the actual instrument configuration, the software will be
unable to interpret and process the data correctly.
To view or modify the .con file:
1. Double click on SBEDataProc.exe.
2. In the Configure menu, select SBE 19plus V2 Seacat CTD. The
configuration dialog box appears; click Open.
Notes:
• See the SBE Data Processing
manual and/or Help files.
• When we ship a new instrument, we
include a .con file that reflects the
current instrument configuration as
we know it. The .con file is named
with the instrument serial number,
followed with the .con extension. For
example, for an instrument with
serial number 2375, Sea-Bird names
the .con file 2375.con. You may
rename the .con file if desired; this
will not affect the results.
• In the 19plus V2 setup commands,
external voltage numbers 0, 1, 2, 3,
4, and 5 correspond to wiring of
sensors to a voltage channel on the
end cap (see Dimensions and End
Cap Connectors in Section 2:
Description of SBE 19plus V2).
However, in the .con file, voltage 0 is
the first external voltage in the data
stream, voltage 1 is the second, etc.
• SEASAVE and SBE Data
Processing use the same .con file.
