ABSTRACT:
A manually operable scanner includes a rectangular frame having suction cups or other mounting devices connectable to a casting or other body to be scanned with a carriage being mounted on the frame for reciprocation in a first direction. A scanner such as an ultrasonic transducer is mounted on the carriage for reciprocation in a direction perpendicular to the direction of movement of the carriage with movement of the carriage and the scanner being sensed by first and second rotary encoders each of which provides an output signal to a display indicative of the position of the transducer with respect to the rectangular frame so that upon a detection of a fault in the body being scanned, the coordinates of location of the fault are immediately available from a visual readout of the coordinates from the display means.
