4-10 A Brief Look at Software 929895 ZonicBook/618E
Software
eZ-NDT software is extremely easy to use, with step-by-step instructions and an intuitive graphical user
interface. Three password-controlled security levels are provided: Manager (full access), Technician
(limited access), and Inspector (test only). Only the Manager can access the setup screens that set the
pass/fail criteria and the known-good resonant signature. Operators are provided with simple, straight
forward screens showing the performance of each part against the predetermined resonant signature and the
pass/fail results.
eZ-NDT software stores several test parameters during normal testing. Users with Manager and Technician
privilege levels can access part-specific information and summary reports, including statistical analysis.
Feasibility Study Service
We offer a service to determine the feasibility of resonant inspection for your parts. This minimizes the
risk of problems during deployment of the final test system. As part of the Feasibility Study, we test a
sample lot of both good and bad parts. The Feasibility Study isolates the resonant disparities between the
two lots and states whether the part-under-test is a good candidate for resonant inspection. When the
system is purchased, we will include the pass/fail criterion developed during the Feasibility Study, and
credit the cost of the Feasibility Study to the purchase of a system.
Theory of Resonant Inspection
When an object is struck by an external energy source, such as “pinged” from a hammer, it will make a
sound that is specific to the physical properties of the object, including its size, weight, density, and
porosity. When an object is pinged with a hammer, the ZonicBook records the sound and sends the
digitized signal to the PC for analysis. eZ-NDT software running on the PC decomposes the sound,
effectively creating a “signature” that is unique to the object being pinged.
Generally speaking objects of similar physical composition will have similar signatures. During the
Feasibility Study, our technician’s determine whether or not your pieces have a unique and measurable
signature, and determine if the signature of known “good” parts is distinguishable from that of known
“bad” parts. If this is the case, the eZ-NDT software “learns” how to distinguish good from bad parts, and
will provide the operator with a simple GO or NO-GO indication after each object is pinged.
