Echo ranging is a technique used to determine
WebThe test object is tested with a high gain setting by which the smallest detectable reflector is displayed. An echo indication is peaked, i.e. the maximum echo indication is achieved by careful movement of the probe and the echo peak set by adjustment of the gain to a predetermined height, e.g. 80% CRT screen height (reference height) , Fig. 65.
