The distance between the first and the second back wall echoes is the same as the distance between the zero thickness point and the first back wall echo If there is an echo between the first two back wall echoes it is probably a mode converted shear wave echo Use the manual echo to echo detection mode techniques and manually adjust the E1 blank to eliminate this error see Blanking Adjustments in Manual Echo to Echo Detection Mode on page 73 Using the D797 transducer beyond 18 mm 0 7 in helps eliminate the possibility of this error In some cases the second or third back wall echo is smaller in amplitude than subsequent echoes which causes the instrument to give a double or triple reading If you are using a D790 transducer this effect may occur around 5 mm 0 2 in on flat smooth steel samples If this occurs it is clearly visible on the waveform display and you can work around it using the manual Echo to Echo detection mode or by moving the extended blank beyond the previously detected first echo When the 45MG cannot make an echo to echo reading the LOS flag appears on the screen In this case the waveform display shows that either no echoes are large enough to be detected or that only one echo is detectable In the latter case the Echo to Echo detection bar begins at the detected echo but extends indefinitely to the right Software Options 75 DMTA 10022 01EN Rev C January 2015 Increase the gain value to

71. EN Rev C January 2015 5 3 e Velocity variations An ultrasonic thickness measurement is accurate only to the degree that material sound velocity is consistent with the instrument calibration Some materials exhibit significant variations in sound velocity from point to point This happens in certain cast metals due to the changes in grain structure that result from varied cooling rates and the anisotropy of sound velocity with respect to grain structure Fiberglass can show localized velocity variations due to changes in the resin fiber ratio Many plastics and rubbers show a rapid change in sound velocity with temperature and as such velocity calibration must be performed at the temperature of the location where the measurements are made Phase reversal or phase distortion The phase or polarity of a returning echo is determined by the relative acoustic impedances density x velocity of the boundary materials The 45MG performs computation based on the customary situation where the test piece is backed by air or a liquid both of which have a lower acoustic impedance than metals ceramics or plastics However in some specialized cases such as measurement of glass or plastic liners over metal or copper cladding over steel this impedance relationship is reversed and the echo appears phase reversed In such cases it is necessary to change the appropriate echo detection polarity in order to maintain accuracy see Detection of Ech
