Abstract
A method is provided of determining waveform stability of a pulse echo layer transducer (PELT) used for measuring paint film thickness of painted bodies. The method includes the steps of reading a signal with the PELT transducer with respect to a desired location of the vehicle. The method also includes the steps of determining whether a maximum absolute value of the read signal is greater than a noise threshold (&phgr;) and computing a measure (&rgr;) based on an option (k). The method includes the steps of determining whether the computed measure (&rgr;) is above or below a predetermined threshold (T) based on the option (k), and concluding a stable/unstable signal from the PELT transducer.
