Figure 11-5 Partial DAC curve with each echo set to 80 % FSH
In the example above (Figure 11-5 on page 231), the instrument has drawn a DAC
curve with three levels from the first point to the second. You have used the AUTO
80 % function to bring the second point to 80 % full-screen height. This assures that
the point is captured accurately because amplitude resolution is better at greater echo
heights. This also pushes the first captured echo over 110 % FSH so the main DAC
curve and the
−
6 dB warning curve extend downward to the second point from o

screen.
While acquiring DAC points, you have three other choices besides
Add
:
•
Delete
Deletes the most recently captured DAC point.
•
Erase
Deletes all captured DAC points (the entire curve).
•
Done
Completes curve acquisition and switches to inspection mode.
