A-scan Display: The A-scan area of the screen displays echo signals during an inspection. The graticule divides the A-
scan area into 5 horizontal and 5 vertical divisions.
The Gate Bar shows the position, width, and threshold settings of the a-gate. The a-gate is both a flaw
monitor/alarm and distance measurement circuit. When set for thickness measurement in multi-echo
mode, a second b-gate is also displayed.
