key to mark the second point; By analogy, to
mark all desired points;
Note: The number of points must be within 8 to 32.
4. When completed the marking of desired points, press
key, it appears trace on the screen
(trace is automatically drawn along the order of marking point until close the beginning point
and end point), the measured values of circumference and area are automatically displayed on
the right part of the screen; If continuously marks the thirty-two point, it directly appears trace
on the screen and the measured values of circumference and area are automatically displayed
on the right part of the screen;

10.3 Volume measurement
A. 2-axis method
Function: Measure the volume of the subject. 2-Axis method only needs to measure the vertical
section of the subject.
Formula of 2-axis method: (π/6) * A * B
