A–Scope

・

The A–scope is a format of echo presentation, showing various echo strength levels in
the form of horizontal deflections, as well as in colors.

・

This function is provided mainly for ease of performance checks, maintenance or
alignment by authorized service engineers and can be activated via the following
keystrokes:

(1) Turn the equipment off.

(2) Turn it on again while holding down the combination of



and



.

Figure 12-1 Typical Echogram Screen with A–Scope Turned on

・

An example display is shown at right.
The size of deflection represents a
relative strength level, i.e. the greater
the deflection, the stronger the echo.

・

The display will remain for approx. 5
minutes and will then be turned off
automatically.

・

The A–scope display will help estimate
instantly an approximate size of an
object as soon as it is detected, thereby
eliminating the need to wait for the
whole block of echoes to become
visible across the screen while
operating on deep ranges or at slow
echogram feed rates.

・

To turn it off quickly, shut down the unit.
