Operations:
Volume (3 Dist)
1. Select [Volume (3 Dist)] from the measurement menu. The cursor appears on the screen.
2. Here, D1, D2, D3 are length of three axes of the target object.
See "3.2.2 Distance" for detailed procedures.
Generally, D1, D2, D3 should belong to different scanning plane.
Volume (Ellipse)
1. Select [Volume (Ellipse)] from the measurement menu. The cursor appears on the screen.
2. The procedures are similar to that of Ellipse in the area measurement, see "3.2.4 Area" for
details.
Volume (Ellipse Dist.)
1. Select [Volume (Ellipse Dist.)] from the measurement menu. The cursor appears on the screen.
2. Use the Ellipse method to measure the vertical section area.
The procedures are similar to that of Ellipse in the Area measurement, see "3.2.4 Area" for
details.
3. Unfreeze the image. Rescan the area of interest perpendicular to the previous image.
4. Measure the length of the third axis with the Distance measurement method, see "3.2.2
Distance" for detailed procedures.
3.2.6 Double Dist
Function: measures the lengths of line segments A and B perpendicular to each other.
1. Click [Double Dist] in the measurement menu, and the cursor appears on the screen.
2. Move the cursor to the measure starting point.
3. Press <Set> to set the starting point of the first line segment.
4. Use the trackball to position the end point of the first axis and then press <Set>. Here,
Press <Update> to switch between the starting point and the end point of the first axis. Or,
