3-2 General Measurement
3.2.2 Distance
Function: Measures the distance between two points on the image.
1. Click [Distance] in the measurement menu, and the cursor appears on the screen.
2. Move the cursor to the starting point with the trackball.
3. Press <Set> to set the starting point.
4. Move the cursor to the end point with the trackball. Here,
Press <Clear> to cancel setting the starting point. Or,
Press <Update> to switch between the fixed end and the active end of the caliper.
5. Press <Set> to set the end point.
3.2.3 Angle
Function: Measures the angle of two crossing planes on the image and the range is: 0°- 180°.
1. Click [Angle] in the measurement menu, and the cursor appears on the screen.
2. Set two line segments as described in "3.2.2 Distance".
The angle appears in the result window after setting the line segments.
3.2.4 Area & Circumference
Function: measures the area and circumference of a closed region on the image. Four
measurement methods are available:
Ellipse: Fix an ellipse region by two equal-cut perpendicular axes.
Trace: Fix a closed region by free tracing.
Spline: Fix a spline curve by a series of points (12 points at most).
Cross: Fix a closed region with two axes perpendicular to each other. The starting point and
the end point of the axes can both be fixed freely.
Tips: These four methods are also applicable to other measurement items, and will not be
repeated when mentioned below. The operations are as follows.
Ellipse
1. Select [Ellipse] in the measurement menu. The cursor appears on the screen.
2. Move the cursor to an area of interest.
3. Press <Set> to set the starting point of the first axis of the ellipse.
4. Move the cursor to position the end point of the first axis of the ellipse. Here,
Press <Update> to switch between the fixed end and the active end of the first axis. Or,
Press <Clear> to cancel the start point of the first axis.
5. Press <Set> to set the end point of the first axis of the ellipse. The second axis appears on the
screen.
6. Move the trackball will increase or decrease the ellipse from the fixed axis. Move the trackball
to trace the area of interest as closely as possible.
Or, press the <Update> or <Clear> key to return to the step before setting the first axis.
7. Press <Set> to anchor the ellipse region, and the measure result will be displayed in the
results window.
Trace
1. Select [Trace] in the measurement menu. The cursor appears on the screen (touch screen).
