Data Conversion
The
Data
Menu
is used to export the proprietary binary
data files into other formats.
Export Matlab
creates .mat files that are directly
readable by Matlab and other common numerical
analysis packages. Note that large data files will be
broken down into smaller .mat files by the export
process.
Export ASCII
creates ASCII data files that may be
imported or read by other software applications (e.g.
Excel).
Due to the amount of data produced, we consider the
Matlab binary export to be the best option. The file can
be read by most common numerical analysis packages
and produces much smaller files than the ASCII
export. For guidance in looking at the data, we
recommend reading the
FAQ’s on single point and
profiling Velocimeters and reference books or articles on
data analysis techniques and methods.
Power and Communication
The Vectrino Profiler is shipped with a 12-pin connector
and cable which supplies external DC power (12-48 V)
and provides two-way serial communication with an
external computer.
The cable also provides
synchronization options.
Synchronizing Multiple Instruments
Your Vectrino Profiler can serve as a master for other
Vectrinos, or other sensors can control its sampling. This
comes in handy when you need to use several
instruments for a single set of measurements. A
description on how to configure the instrument for
synchronization can be found in the
SW User Guide
.
Troubleshooting
As most problems are caused by simple mistakes,
please initially check if
you have forgotten to power the system
the connector has fallen out of the computer
you are using the wrong serial port or baud rate
You may find that there is a lot of noise in the velocity
data. This may be caused by
not enough particles in the water
the velocity range set too high
the sampling volume located beyond the bottom
reflection and reverberation conditions at
the bottom
probe malfunction. Test the probe with the Probe
Check feature
When all obvious mistakes are ruled out, please turn to
