Line Density
You can adjust the line density of the Color mode image. Increasing the line density
decreases the frame rate. You get finer color resolution but a slower refresh rate. The
view must be scanning when you do this
Line density is not available when Auto is turned on.

•
Click Line Density under Color on the left side of the screen and select the
value you want (or point at Line Density and press
[
+/-
]
).
The available values range from 1 to 5.
The current setting is displayed on the screen next to Line Density.
Color Quality – Shots per Estimate
One way to improve the accuracy of the color-coded velocity information is to
increase the number of pulses transmitted in each waveform packet (shots per
estimate) at the expense of decreasing the frame rate. The view must be scanning
when you do this.
Shots Per Est. is not available when Auto is turned on.
To adjust the color quality (select shots per estimate):
•
Click Shots per Est. under Color on the left side of the screen and select the
value you want (or point at Shots per Est. and press

+/-
]
