Sine curve data plotFigure 7-47:
On the sine curve data plot, the amplitude versus degree data is shown.
When a cursor is active, the following data values for the selected point are
displayed below the plot:
• Point—Number of the selected point.
• Angle—Angular position of the selected point.
• Vert—Actual vertical position of the selected point. The background is green for
an active point and red for a deleted point.
• Est—Amplitude value of the sine fit curve at the particular angular position.
The following calculated sine curve values are displayed at the bottom of the
analyzer screen:
• Phase—The plus zero transition position.
• Offset—The centerline of the laser beam travel on the sensor in the radial
direction. The initial position of the laser beam on the sensor affects this value.
• Amplitude—The maximum displacement of the sine curve from the offset line.
• Correlation—The confidence factor in percent that is used to determine the
quality of the sine curve data.
