With the general parameters for the Trigger Set defined the actual ranges themselves can be defined via the 'Trigger Levels' button. Click 'Add' for the first of the ranges for assessment, defining the expected filters as required.
Repeat the process for the other values in the range. Note that the Add button will create a new blank row; using the Copy button will duplicate the selected rows (this is particularly useful where chemical species are similar in their nature and so share the associated trigger values).
Where the Copy button has been used for the same combination of filter values the ranges will automatically increment. It is also advisable to define a unique Code to allow the assessment to be traced in a CSV export from an assessed grid (this is necessary as the colours are not supported in the CSV format).
It is also possible to bulk update a selection of values. This can be used in conjunction with the copy option to create different bands of values for different situations. Simply select the required values and select the Update button.
Select the column which is to be updated and select the new value, then select Update. All of the previously selected values will not be updated to the new value. Click on Save to commit any changes to the database.
