Circumference and Area Measurement
▐ 2D Ellipse
This is a basic measurement that is available in all diagnosis modes. You can measure the
circumference and area of a circular (elliptical) object in a 2D image.
You can measure up to 4 distances. When taking more than one measurement, use
measurement cursors with different shapes (+, X, #, *) to differentiate them.
1. Select the Flexible Soft button [2] Ellipse. “2D Ellipse” is displayed in the user
information area.
2. Use the Trackball and the Set button on the control panel to specify the diameter
(axis) of the measurement area.
- Place the cursor at a desired position with the Trackball, and press the Set button.
Tip! Repositioning Point
Pressing the Change button before pressing the Set button to complete positioning resets
the position of a point just set.
3. Specify the size of the circle (ellipse).
- Adjust the size using the Trackball, and press the Set button.
4. When the measurement is finished, its result is shown on the screen.
- Circ.: Circumference of Object
- Area: Area of Object
- Avg.(C): Average Circumference
- Avg.(A): Average Area
5. A new measurement cursor appears. When more than 4 straight lines are specified,
the lines are deleted in the order in which they have been specified.
