The miniDOT Plot program plots the files recorded by
the miniDOT Clear Logger. The program reads all the
miniDOT Clear 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 Clear Logger. If the miniDOT Plot
program is run directly from the miniDOT Clear Logger, then the program will suggest the folder that
is located on the miniDOT Clear 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 Clear 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
Clear Logger is slow.
The miniDOT Clear Logger’s measurement folders must NOT contain any files besides those the
miniDOT Clear Logger recorded and the CAT.txt file.
Click “Plot” to begin plotting.
The program reads all the miniDOT Clear Logger’s data files in the selected folder. It concatenates
these and presents the plot shown below.
