2-5. Measuring blood velocity
This section explains the fundamental use of measuring blood velocity. Refer to “3.
Appearance and Mode Settings” for various uses.
(1) Connect the probe to the probe connector so that
the polarity mark will be placed under
mark as shown in the right (12 o’clock).
(2) Put ultra ultrasonic gel on the probe top or patient
skin.

(4) Put the probe on the measurement area and
move it slowly to locate the point where the
maximum Doppler sounds are heard. An ideal
probe angle to the vessel is approximately 45 to
60 degrees.
(5) When the waveform becomes rhythmical and
stable, wait more than 5 sec without moving the
probe, and then press the probe button to freeze
the waveform. Press Print Button to print the
waveform of last 5 sec. if necessary.
