After selecting a file, data logging begins immediately. The
number of logged measurements is shown just below the
concentration plot.
The log file header contains calibration information, the
computers current time zone, and the instrument serial number.
The header is followed by three columns of data: date, time,
and concentration (mg/L).
Data Plotting
The LISST-ABS software automatically plots concentration as a
function of sample number.
Data shown in the plot is color coded to indicate what operation
the software is preforming. If the concentration is simply being
displayed with no logging or calibration being performed, data
are plotted in blue. If concentration is actively being logged to a
text file, data are plotted in green. If the instrument is currently
