5-1. Arterial and venous blood velocity modes
Arterial and venous blood velocity can be measured on these modes by Doppler
technique. Smartdop displays and prints waveform as follows:
Mode 1:
Displays approx. 2.56 sec of waveform per screen of LCD
Prints waveform in time scale of approx. 25 mm/sec.
Forward and reverse components are combined.
Mode 2:
Displays approx. 12.8 sec of waveforms per screen of LCD
Prints waveforms in time scale of approx. 5 mm/sec.
Forward component (arterial) is separated from reverse component (venous).
For typical operation for blood velocity modes, see “§ 3-5. Measuring Blood Velocity”.
5-1-1. Waveforms on LCD

The base line is automatically located at best position depending on how big the
reverse component is. Smartdop has 4 base lines, the bottom, 1/4 from the bottom, the
center, and 3/4 from the bottom.

The waveform amplitude is automatically adjusted for optimal observation.

The velocity amplitude scale per division is shown at top left of LCD.

Memory number is shown at top right of LCD for waveform read on MEMORY mode.
