The miniDOTPlot program plots the files recorded by the miniDOT Logger. The program
reads all the miniDOT Logger files in a folder, except the CAT.txt file. The program will also
compute air saturation from the dissolved oxygen measurements. To do this, the program
must know the air pressure and salinity. It calculates air pressure based on elevation of the
water surface above sea level or uses the barometric pressure you enter if Barometric
Pressure is selected. If the 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
that is located on the miniDOT Logger’s SD card. You may accept this by clicking “Plot”, or
you may click “Select DATA Folder” to browse to 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’s measurement folders must NOT contain any files besides those the
miniDOT Logger recorded and the CAT.txt file.
Click “Plot” to begin plotting.
The program reads all the miniDOT Logger’s data files in the selected folder. It concatenates
these and presents the plot shown below
