This is one of a series of pages for setting up a data log. Changes are not saved until you click Finish on the last page in the series.
Because this is a panel data log, you select the trend to be logged in the Trend Name column, which corresponds to data point shown in the Data Point column.
The Interval column shows the sample rate used by the panel. You can collect the data for your data log in Tracer Ensemble at the interval from the panel or at a different rate of your choosing.
