(Note: this menu needs professional person for operation):
FALSE ECHO EDITION
START POINT
1.00 AMPLITUDE 1300m(d)
END POINT 2.00 AMPLITUDE
1500m(d)
Two points can be edited a time, the start point and the end point are the
coordinates for the curve which is needed to be edited. The following
corresponding value of amplitude is the value to be edited (Note: when
input or alter the distance coordinates, the corresponding amplitude will
automatically be updated according to the currently saved value which will
act as reference for amplitude modification).
When the modification for the two pairs of coordinates is finished, press
button OK for confirmation of the modification. The instrument will
automatically link the two points and create a new false ECHO GRAPH,
substitute for the old curve. Press button OK for confirmation, LCD will
indicate the false ECHO GRAPH after the modification this time for
reference.
And then press button ESC, LCD goes back to the edition interface for
further edition. When the false echo edition reach to the request of the
