Use this button to enable a single data point or a range of data points. Any data points thus undisabled will be flagged "G" for "good" and will be used in any analysis or calculations until it is disabled. Points already undisabled are not affected.
Select the lines to be enabled in the Data grid by clicking and dragging the mouse. Only contiguous ranges of lines of data may be enabled using this feature. Non-contiguous lines must be enabled individually.
