    DMTA-10004-01EN, Rev. D, November 2016 NOTE You can also achieve a material sound velocity and zero calibration procedure by performing the operations in the reverse order, starting with the zero calibration, followed by the material sound velocity calibration. 5.2.5 Entering a Known Material Sound Velocity When preparing to measure thicknesses on parts made of a different material, if you know the sound velocity for the material, you can directly enter the velocity without performing a material sound velocity calibration procedure.

  • Page 85: Locked Calibrations

    Calibration The accuracy of any ultrasonic measurement is only as good as the accuracy and care with which you calibrate the instrument. The 38DL PLUS ships from the factory with standard setups for a number of transducers and applications. In some cases, it may be desirable to optimize these setups for specific measurement situations.
  • Page 86 DMTA-10004-01EN, Rev. D, November 2016 maximum accuracy is to be achieved, then the coupling technique must be consistent. In order to accomplish consistent measurements, use a couplant of reasonably low viscosity; employ only enough couplant to achieve a reasonable reading; and apply the transducer with uniform pressure. Practice will show the degree of moderate to firm pressure that produces repeatable readings.

  • Page 87: Measuring Thicknesses

    The phase or polarity of a returning echo is determined by the relative acoustic impedances (density × velocity) of the boundary materials. The 38DL PLUS assumes 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.

    The 38DL PLUS offers three parameters to draw a time-dependent gain curve: INIT GAIN, TDG SLOPE, and MAX GAIN (see Figure 13-8 on page 230). From the initial gain level, receiver gain slopes up to the maximum gain level at the rate determined by the TDG SLOPE setting.

    DMTA-10004-01EN, Rev. D, November 2016 13.7 Main Bang Blank The main bang blank is effectively a blank zone that protects the receiver from false readings generated by the main bang. This blank or dead zone (up to 18 microseconds from the excitation pulse) prevents the detection of the trailing edge echoes of the excitation pulse as if they were back-wall or interface echoes.

    The 38DL PLUS comes standard with a USB cable for communicating using the USB 2.0 protocol. You must purchase an optional RS-232 cable (see Table 23 on page 246) to use RS-232 communication. The 38DL PLUS can send data to any device capable of receiving ASCII-formatted data using the RS-232C/D protocol. This includes personal computers, minicomputers, dataloggers, and printers.

  • Page 256: Setting Up Usb Communication

    Press [MEAS] to return to the measurement screen. Connect one end of a USB cable to the USB client connector under the I/O door of the 38DL PLUS, and the other end to a USB port of the computer (see Figure 14-1 on page 245).

    The 38DL PLUS can transmit stored data and displayed readings over its input/output (I/O) RS-232 cable to any device with a RS-232 serial interface. The 38DL PLUS can also receive and execute commands sent from any device with a serial interface. Such devices include personal computers and printers.

  • Page 258: Table 23 Optional Rs-232 Cables

    Since all computers do not have the same serial port connector, the correct cable must be ordered from Olympus. The RS-232 cable is an option for the 38DL PLUS, which you can specify at the time of order (see Table 23 on page 246).
