Abstract
An indicating system is disclosed for use with nondestructive testing systems of various types including an eddy current instrument in which the characteristics of a specimen structure are indicated by the form, position and dimensions of a trace on a screen. The system indicates whether or not the relationship of two test signals is within certain limits which can be shown in the form of outlines or a series of contiguous boxes on a screen. Prior to the testing of a structure of unknown characteristics, such limits may be learned or recorded by the system either during the manual manipulation of a joystick control or the like or during the testing of a structure of known or standard characteristics.
