selected. If Surface Elevation is entered, then no compensation for weather-induced
barometric pressure variation is made. Enter elevation or barometric pressure. Enter water
salinity.
Select the folder that contains the files recorded by the miniDOT Logger. If the miniDOTPlot
program is run directly from the miniDOT Logger, then the program will suggest the folder
located on the miniDOT Logger. You may accept this by clicking “Concatenate”, or you may
click “Select DATA Folder” to browse your HOST computer’s hard drive. If the number of
measurements recorded is small, for example a few thousand, then these can conveniently
be plotted directly from the miniDOT Logger’s storage. However it is best to copy large
measurement sets to the HOST computer and select them there. The file access to the
miniDOT Logger is slow.
The miniDOT Logger measurement folders must NOT contain any files besides those the
miniDOT Logger recorded and the CAT.txt file.
Click “Concatenate” to begin concatenating files and create the CAT.txt file.
The CAT.txt file will resemble the following:
End the miniDOTConcatenate program by closing the window.
Chapter 3: miniDOT Logger
3.1 Overview
All miniDOT Logger measurements are saved in files on the SD card inside the miniDOT
Logger. The files are transferred to a HOST computer via a USB connection where the
miniDOT Logger appears as a “thumb drive”. Measurements may be plotted by the
miniDOTPlot program and files concatenated by the miniDOTConcatenate program. The
miniDOT Logger itself is controlled by the miniDOTControl program. Customers are
required to open the logger each time measurements are transferred to the HOST computer.
This chapter describes the miniDOT Logger’s internal features.
