7.4.2 Adjusting Baseline
Adjust the zero baseline up or down in the Time Series window.
To adjust the baseline:

velocity calculation is usually too large to use.
• To toggle the angle between -60° and 60°, touch Angle -60,0,60 repeatedly.
• Touch Angle +/- to adjust the angle to the desired number.
• To manually adjust the angle, touch and hold one finger on the Spectral Doppler cursor, then flick
