Cell Begin / Cell End
• Specify the location of the start and end of the measurement volume. The standard
deviation (accuracy) of the velocity data is inversely proportional to the square root of the
measurement volume size (cell end minus cell begin); larger measurement volume size
gives lower standard deviation. See the Argonaut Principles of Operation for more details.
The acceptable range is from 0.5 to 14.8 m.
Data Format
• This parameter is not used with the real-time software.
Dynamic Boundary
• This variable allows the Argonaut XR to automatically adjust the upper end of the
measurement volume based upon data from the pressure sensor. A setting of DISABLE
turns off the dynamic boundary adjustment and uses the fixed cell location parameters
entered above. A setting of INTEGRATED will use the fixed value of cell begin and will
adjust the end of the cell to be as close as possible to the surface. A setting of LAYERED
will measure a layer whose thickness is defined by (Cell End – Cell Begin), with the upper
edge of the layer as close to the surface as possible.
Wave Spectra
• See Section 8 in the Argonaut Operation Manual.
Record File Name
• This specifies a root file name for data files recorded by the real-time software.
• Up to five letters and/or numbers can be specified.
• A 3-digit termination is added to the specified file name, starting with 001 and
incrementing (002, 003, …) each time recording is stopped and started.
• The file names use the extension .ARG. For example, if the file name is TEST, the first file
will be TEST001.ARG, followed by TEST002,ARG, etc.
• Files are stored in the directory shown under the File|Open option.
Comment 1/2/3
• Up to three comment lines are provided for you to document the data set.
