8.3.11 Dynamic
Set
“Dynamic Set” controls the axial resolution of color in the display.
It adjusts the axial sample depth of color pixels.
When rotating counter-clockwise the color information is sharper (edges more pixely).
When rotation clockwise the color information is less sharp (edges smoothed).
Rotate the

digipot and select the desired dynamic range. Set 1 to Set 8.

4-8 color samples in axial direction larger
Remarks:

Changes are only possible in write mode.
8.3.12 Smoothing
A temporal average is determined from several color images, so that different filter periods can be
selected for rising velocity and falling velocity.
Rotate the

]
digipots and select the rise and the fall filter.
RISE:
Filtering of the rise velocity leads to noise suppression.
To be used with small laminar flows. Avoid quick movements of the probe, because the flow
is "built up" slowly. When displaying pulses the Rise-Filter must be set low.
FALL: This filter leads to prolongation of the displayed flow.
To be used with quick pulses (short "color flashes") to prolongate them for better evaluation
on the monitor.
Remarks:
*
Changes are only possible in write mode.
