distribution
window More detailed information, such as detailed size distribution, raw light
scattering values, and system values, is available for each
measurement.
To access this information, double click on a measurement point in
the Total Concentration plot (the bottom strip chart).
To open the most current sample double click on the right most
sample.
A window will appear that shows the current detailed size distribution.
The plot shows the 32 log spaced size classes. Size class 1 is 2.5
microns and size class 32 is 500 microns. The date and time of the
sample is shown on the title of the display.

scattering and
background
light levels To access the raw light scattering for this sample click on the Raw
Data tab at the top of the size distribution display window. The raw
light scattering is useful in trouble shooting any technical problems.
For example, for the system to work properly the optical windows that
the laser beam passes through must be clean. To correct for any
additional scattering coming from these windows a clean water
background is obtained before each measurement. If the windows
are slightly dirty this background measurement will automatically
correct the data before processing the size distribution. This clean
