Making a velocity
flow trace
measurement
1. Select the measurement; an active caliper displays.
2. To position the caliper at the start point, move the Trackball.
3. To fix the trace start point, press Set.
The system displays a vertical dotted line.
4. To trace the envelope, move the Trackball.
A line shows the traced area.
5. To complete the trace, press Set.
The system displays a second vertical dotted line.
6. To position the second dotted line at the start of the next
envelope, move the Trackball.
7. To complete the measurement, press Set.
The system displays the measurement in the Results
Window.
