Set "Denoising Range".
Set the denoising range checking the graph or the result of each cell (Cell Result).
Refer to page 171 for details of Cell Result.
The figure below shows an example that Denoising is not used. Multiple edges in the two areas are
targeted for measurement.
Using Denoising function displays a line to divide the range of unused edges from the range of used edges
as below.
Enter a value in Denoising Range and press the ENTER key to move this line.
Check the graph and make the setting to let the target edges in the range of unused edges.
Setting the denoising range to a larger value expands "Used edge range".
The "x" mark (red) in the graph indicates the cell that detects no edge.
Although it is displayed in the used edge range, it is counted as an unused edge.
