Smoothing (Smooth)
If there is a lot of noise in the graph, carry out smoothing. If there is a small amount of
noise over the entire graph, select Average. If there is spike-shaped sporadic noise, select
Median.
If you perform smoothing, the data changes from the pre-processed value as a result
of the smoothing computation. For this reason, be very careful when evaluating the
data after carrying out smoothing.
1.
Select Process from the menu, then select Smooth in the pull-down menu.
2.
Set Method to Average, specify the number of points to be used for smooth-
ing, then select OK.
Smoothing takes place, and the data is displayed.
It is recommended that you use between 5 and 7 points. Note that several points
at the edge of the graph are not smoothed.

Evaluating the Measurement Values (Measure)
You can measure the values at arbitrary points on the graph or the difference between the
values at two points.
1.
Click on Measure shortcut icon.
The Display Window will appear.
2.
Drag the red and green markers on the graph to set the measurement points.
The value at the mark position and the relative value between the red and green
markers are displayed on the right of the graph.
3.
Press the right mouse button to exit processing.
You can freely move the marker position until the time when you click on the right
mouse button (during the time the mouse courser’s shape is fingered).
