Trace
This is a basic measurement that is available in all diagnosis modes. Measure the circumference
and area of an irregularly shaped object on a 2D image.
1. Select Trace on the monitor or touch screen.
2. Use the trackball and the Set button on the control panel to specify the start point for tracing
over the contour of the measurement area.
Use the trackball to place the cursor at the desired position and then press the Set button.
3. Trace the curve so that the measurement cursor returns to the start point, and then press the
Set button.
NOTE: The Trace Line must be a closed curve. If you press the Set button before tracing is
complete, a straight line will be traced between the current position and the start point, resulting in
a significant error.
4. When the measurement has been taken, the result is shown on the screen.
The equations used for Trace measurement are as follows:
X
, (N = 1, 2… last point)
X
, (N = 1, 2… last point)
Tips!
Editing Curves
Before specifying the end point by pressing the Set button, you can delete part of the curve being
traced by rotating the soft menu dial-button 5 clockwise. To restore the deleted curve, rotate it
counter-clockwise.
