NON-DESTRUCTIVE TESTING INSTRUMENT WITH DISPLAY FEATURES INDICATING SIGNAL SATURATION
First Claim
Patent Images
1. A non-destructive testing instrument configured for performing measurement on a test object and providing measurement results, comprising,a probe sending a testing energy into the test object and receiving an echo signal from the test object during a data acquisition session;
- a data acquisition unit receiving and converting said echo signal to digital signal, for the data acquisition session;
a display viewing unit;
a digital logic and processing unit detecting said digital signal to be either saturated or non-saturated for the data acquisition session, and processing said digital signal and for displaying the measurement results on the viewing unit when the digital signal is non-saturated;
whereas providing and causing to display an alert flag on the viewing unit, and further causing an abandonment of the digital signal so that the measurement results for the acquisition session are not displayed on the viewing unit.

Abstract
Disclosed is a non-destructive testing instrument configured, when the digital signal is saturated during one data acquisition session, to display an indicator flag to warn the operator in order to help the operator to clearly see that a measurement is invalid. It'"'"'s also configured to abandon and not to display the measurement results to stop any further analysis on them.

9. A method of alerting and blocking a saturated data acquisition session in a non-destructive testing instrument, the instrument is configured for performing measurement on a test object and providing measurement results,
the method comprises steps of: -
sending exciting testing energy into the test object and receiving an echo signal from the test object during a data acquisition session; receiving and converting said echo signal to digital signal, for the data acquisition session; detecting the digital signal of being saturated or not being saturated; displaying a waveform and/or measurement value pertaining to the digital signals of the acquisition session if the digital signal is not saturated; displaying a warning if the digital signal is saturated, and blocking display of the waveform and/or measurement value when the digital signal is saturated if the digital signal is saturated. - View Dependent Claims (10, 11, 12, 13)
