6.3.9 Baseline
BASELINE
Moving the baseline increases the velocity range in one direction, the zero position also
moves as a result. The maximum velocities in both directions are displayed at the ends of
the Spectral Wedge (15, Figure 2.4 ).
• Flip the
BASELINE
button to move the baseline up or down to move the baseline;
or
• Select
BASELINE from the context menu, turn the

reduced.
Lower frequency delivers better display of high flow velocities, but the penetration depth is
increased.
• press
to select FREQUENCY .
• turn the function knob to change the frequency.
