OPEN A BINARY DATA FILE
To stop reading the data file currently in use, select the <F> option and enter the name of a
new file. You will then be returned to the main menu with the file pointer positioned at the
beginning of the file. This option is also useful if you wish to quickly reposition the file pointer to
the beginning of the file. It will dump any binned or averaged data in memory and will reset the
program to the binary file mode.

GRAPHICS DISPLAY
This option will present you with the menu illustrated in Figure 3.5. The plotting parameters
shown initially are those recorded in the DEFAULTS.CFG file. To alter any of the listed
parameters, enter the number to the left of the selection. You will then be prompted
accordingly. The format of these plots is depth versus up to four selected parameter(s). Depth
is displayed on the vertical axis of the plot in ascending order, while the other parameters are
displayed on the horizontal axis.
Figure 3.4. M24-READ Vertical Profile Plotting Parameters.
The following describe the selectable parameters in Figure 3.4:

Minimum and Maximum Plotting Depths.
The minimum depth displayed here means
that all readings shallower than this depth will be rejected, but the plot axis will always start at
zero. This is done because of the convention of starting plots at the surface while needing an
easy method of filtering out erratic data recorded near the surface. The maximum depth in this
option will be both the points where plotting stops and where the axis stops.
