YSI 9600 - Manual (Page 111)

The TSS parameter (only available if your sonde has a Turbidity sensor) is a parameter that is not
part of your original collected data. TSS is calculated by EcoWatch, which uses the Turbidity data
and a set of correlation points that you enter. When you add TSS, a TSS calibration window will
popup and prompt you for a set of correlation points. For more information see Calibrate TSS.
Units
Select the units for any parameter. It will take you to the Change Parameter Units dialog box.
You may choose the units for each of the selected parameters. Many parameters have only one
possible choice of units. DO concentration, for example; can only be expressed in mg/L. pH has
no units at all.
Attributes
This command takes you to the Change Parameter Attributes dialog box where you have access
to two powerful features. You can choose to display an average of your data, or graph the data
with some parameter other than time for the x-axis. The most common use for this latter feature is
to graph temperature and DO versus depth. Other combinations are possible. You may choose to
average the data before it is graphed. An interval of 0 will cause there to be no averaging at all.
The larger the averaging interval, the more points will be used in each average. For example, if
