Abstract:
1. A non-destructive inspection (NDI) instrument for testing an object, the instrument comprising: a transducer transmitting and receiving acoustic energy and converting the acoustic energy to electronic signals; at least one analog to digital converter for converting the electronic signals returned from the transducer into a series of digital signal values; at least one signal processor for processing and aggregating the digital signal values into groups of values associated with different compression zones and for identifying for each data group, a minimum value, a maximum value and, if available, at least one signal peak value; at least one display unit for producing and displaying graphical representations depicting information associated with the digital signal values and the minimum value, the maximum value, and the peak value; wherein the instrument including a facility which causes some of the digital data values at boundaries between compression zones to be shared by adjacent compression zones.
