  • Page 65: Calibrating The Instrument

    DMTA-10022-01EN, Rev. C, January 2015 5.2.1 Calibrating the Instrument To make accurate measurements, you need to perform the following calibrations: • Material sound velocity calibration • Zero calibration The calibrations must be performed using a thick and a thin sample of precisely known thicknesses.

  • Page 68: Test Blocks

    DMTA-10022-01EN, Rev. C, January 2015 5.2.2 Test Blocks The 45MG comes with a cylindrical stainless steel test block with two thicknesses. Two precisely known test-block thicknesses can be used to perform the material sound velocity and the zero calibrations. Precision step test blocks are also often used when more than two known thicknesses are needed (see Figure 5-8 on page 58).

  • Page 69: Material Sound Velocity And The Zero Calibrations

    The 45MG compares the measured time of flight to the expected time of flight based on the current sound velocity. The 45MG displays a warning message if doubling is suspected.

    5.2.6 Locked Calibrations The 45MG includes a password-protected locking function to prevent changes to setups, and prevent access to certain functions. A change to the calibration is one action that can be locked. In such case, the message shown in Figure 5-10 on page 61 appears momentarily on the help text bar (see “Locking the Instrument”...

  • Page 71: Factors Affecting Performance And Accuracy

    Calibration The accuracy of any ultrasonic measurement is only as good as the accuracy and care with which you calibrate the instrument. The 45MG ships from the factory with standard setups for a number of transducers and applications. In certain cases, it may be desirable to optimize these setups for specific measurement situations.
  • Page 72 DMTA-10022-01EN, Rev. C, January 2015 couplant than larger-diameter transducers. In all modes, tilting the transducer distorts echoes, and causes inaccurate readings, as noted below. Curvature of the test piece A related issue involves the alignment of the transducer with respect to the test piece.

  • Page 73: Measuring Thicknesses

    Phase reversal or phase distortion The phase or polarity of a returning echo is determined by the relative acoustic impedances (density × 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.

  • Page 74: Figure 5-11 Coupling A Dual Element Transducer

    DMTA-10022-01EN, Rev. C, January 2015 NOTE In general, use a thinner couplant (such as propylene glycol, glycerin, or water) for smooth material surfaces. Rough surfaces require a more viscous couplant, such as gel or grease. Special couplants are required for high-temperature applications. Using moderate to firm pressure, couple the tip of the transducer to the surface of the test material, and keep the transducer as flat as possible on the material surface (see Figure 5-11 on page 64).

  • Page 75: Saving Data

    Figure 5-12 Reading the measured thickness Saving Data The 45MG optional datalogger is a file-based system, in which one file is opened at a time.

  • Page 161: Adjusting The Extended Blank With Dual Element Transducers

    Incorrect use of the extended blank can cause the gage to misread areas of thin material. Normally, the 45MG searches for echoes down to nearly zero thickness. However, some special circumstances, such as a high degree of near-surface corrosion, aluminum material, enclosed flaws, or laminations, can generate echoes that the instrument may falsely detect as the low thickness.

    DMTA-10022-01EN, Rev. C, January 2015 To use the extended blank Press [GAIN/WAVE ADJ] (only available when the waveform is active). The waveform adjustment parameter and its value appear on the measurement screen (see Figure 9-2 on page 152). If needed, use the [] and [] keys to select EXT BLANK. The extended blank becomes active, but initially, its value is zero.

  • Page 163: B-Scan

    NOTE If the measurement point changes when the extended blank is moved, echoes can change in height. This is because in the normal waveform display mode, the 45MG attempts to adjust the height. The instrument also attempts to make the most accurate measurement by identifying the beginning of an echo.

    Once the Single Element High Resolution option has been activated, the 45MG includes predefined setups for standard single element transducers. In some cases, a 45MG ships from the factory preprogrammed with one or more custom setups to meet special customer requirements. You can create your own custom setups to meet the need of a particular single element transducer, or for a particular application.

    Refer to “Echo Window” on page 177 for information on the modes in relation with the echo window. 10.4 First Peak With single element transducers, the 45MG normally detects peaks on either the highest positive or highest negative peak of the RF waveform. This feature works well for most precision thickness applications.

Higher voltages may provide greater penetration at the expense of a lower near- surface resolution, especially in mode 1.

    Figure 10-7 Comparing pulser powers set to 60 V and 200 V NOTE When the 45MG displays the SAT flag below the thickness reading, the input voltage from the transducer is above the maximum range, and proper measurements cannot be made. This can normally be corrected by lowering the PULSER POWER until the SAT flag no longer appears.

By effectively making the excitation pulse or interface echo smaller, the TDG curve allows for detection of echoes occurring close to the pulse.

In mode 1, however, the length of the main bang blank determines the minimum thickness that can be measured, and must therefore be positioned with care after selecting the initial gain level (see Figure 10-9 on page 176).
