TAMAX and TAMEAN (continued)
Auto Trace
NOTE:
2-64
The value measured depends upon the Vol Flow Method preset.
The two selections available are: Peak (TAMAX) and Mean
(TAMEAN).
To auto trace TAMAX:
1. Press Measure key in Measure mode to select Trace.
Select Auto or in the Utility -> Measure - Advanced preset
menu set Trace preset to Auto.
2. To position the caliper at the trace start point in the Doppler
spectrum, move the Trackball.
3. To fix the start point, press Set.
4. To position the vertical caliper at the end point, move the
Trackball.
5. To complete the measurement, press Set. The system
automatically fixes both calipers and traces the maximum
value between the two points. The system displays this
value in the Results Window.
When you set the Auto Trace for Both (above and below),
the system picks up the maximum power of the signal, NOT
the maximum velocity. If the maximum velocity is not the
maximum power, the system may not trace accurately. If
you want to use maximum velocity, select either Above or
Below.
