Add/Remove
There are two lists,
Selected Parameters
and
Available Parameters
. If, for example, you wish
to graph another parameter, you must highlight it on the
Available Parameter
list and then click
the Add button to move it over to the
Selected Parameters
list.
This is also where you decide the order in which the parameters will appear in both the table and
the graphs. If you choose to have two traces per graph, then the first graph will have the first and
second parameters on this list, the second graph will have the third and fourth parameters and so
forth. The parameters will appear in the
Selected Parameters
list in the order that they were
added. To rearrange the order, highlight the parameter you wish to move and then use the up and
down buttons to move it to the desired spot in the order.
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.
