• Ellipse: fix an ellipse region by two equal-cut perpendicular axes.
• Trace: fix a closed region by free tracing.
Ellipse

1. Select [Ellipse] in the measurement menu.
The cursor appears on the screen.
2. Hold and drag the cursor to an area of interest.
3. Tap on the screen to set the starting point of the first axis of the ellipse.
