Manual revision 006 Section 4: Deploying and Operating SBE 19plus V2 SBE 19plus V2
89
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 (.xmlcon or .con) File
To convert the .hex (raw data) file, you need a .xmlcon or .con configuration
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 configuration file information to interpret and
process the raw data. If the configuration 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 .xmlcon or .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:
Seasave and SBE Data Processing
versions 7.20a introduced .xmlcon
files (in XML format). Versions 7.20a
and later allow you to open a .con or
.xmlcon file, and to save it to a .con
or .xmlcon file. Seasave and SBE
Data Processing use the same file.
A new or recalibrated CTD ships
with a configuration file that reflects
the current configuration as we know
it. The file is named with the
instrument serial number, followed
by a .con extension. For example,
for a CTD with serial number 2375,
Sea-Bird names the file 2375.con.
You may rename the file (but not the
extension) 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 .xmlcon or .con file,
voltage 0 is the first external voltage
in the data stream, voltage 1 is the
second, etc.
