The measurement display on the spec- trum and the corre- sponding result are numbered.

• Velocity and pressure at anchor point positions • Velocity (V3) and pressure (p3) differences between

anchor point position

• Time difference (dT) between anchored points position 7. To assign a label to the measurement, see page 99. 8. Repeat steps 3 through 6 to make additional

measurements.

Manual Doppler trace measurements

Alternative: Press

Caliper and select Manual trace from

the pull-down menu.
