How to apply the Smoothing function into a measurement?
The Smoothing function is to reduce ripples in a measurement. Below are the steps to apply the function on a measurement or measurements.
Select the measurement or measurements to modify, and select the Smoothing command from the Data Handling menu to display the Smoothing dialog.
In the Smoothing parameters box:
Select a smoothing algorithm in the Algorithm dropdown box.
Enter a value in the Sliding window size box. It defines the mean value region used for each smoothing operation. The larger the size, the larger the smoothing effect.
Enter a value in the Resolution box, which defines the point distance in the curve(s) for the interpolation algorithm.
Smooth between box:
To restrict the smoothing to a certain part of the curve(s), two points in the profile are defined in this box. Smoothing will be performed between these two point.
Using the Start and stop coordinates option smooths the complete curve, whereas the Cursor positions option only smooths the area between the cursors (only available if cursors are enabled).
If you have zoomed to a certain view, selecting the Zoomed area option will only smooth the zoomed area.
For user-defined smoothing range, select Defined range and then enter the start and end values in the From and To boxes, respectively.
For profiles, the smoothing ranged can be also defined as the center range as percentage of the field size by selecting Inner field region (only profiles) and the entering a value in the Percentage box.
In the Smooth what box:
A selection is possible, whether only the Selected data shall be smoothed or All data. All data means the data displayed in the currently opened window and not all data in the project.
In the Original Data box:
If the modified data and the original data should be shown at the same time, choose Keep the original data in the group, Original data.
in Peak Analysis box:
Peak analysis is used to prevent over-processing due to bad quality of a curve. The tolerance for peak analysis is defined in Common Settings -> Analysis Parameters -> General Tolerances. It is not recommend to perform smoothing if failed. By clicking the OK button, smoothing will be performed regardless of the validation status.
