Page 4: Overview
1 Overview The model MT660 is a multi-mode ultrasonic thickness gauge. Based on the same operating principles as SONAR, the instrument is capable of measuring the thickness of various materials with accuracy as high as 0.1/0.01 millimeters. The multi-mode feature of the gauge allows the user to toggle between pulse-echo mode (flaw and pit detection), and echo-echo mode (eliminate paint or coating thickness). -

The transducer is the “business end” of the instrument. It transmits and receives ultrasonic sound waves that the instrument uses to calculate the thickness of the material being measured. The transducer connects to the instrument via the attached cable, and two coaxial connectors. -

To insert the batteries: Loosen the two screws of the battery cover. Lift the cover off upward. Insert the batteries into the battery compartment. Close the battery compartment and fasten the screws. Turn on the instrument to make sure the battery is installed correctly and firmly. -

The main unit and the display is switched off and consumes almost no energy. Pressing any key will stop the unit entering power off state while it prompts out “Idle Timeout!” and return back to run state. -
Page 12: Sound Velocity Calibration
5 When the progress bar shows complete, remove the transducer from the probe disc. If necessary, repeat this procedure for times. 6 At this point, the instrument has successfully calculated its internal error factor, and will compensate for this value in any subsequent measurements. When performing a “probe zero”, the instrument will always use the sound velocity value of the built-in probe-disc, even if some other velocity value has been entered for making actual measurements. -

3. Press the to enter the “Input Nominal Thickness” dialog. See right figure. Press F1/F2 to input the thickness value, until it matches the thickness sample piece. -

In order for the transducer to do its job, there must be no air gaps between the wear-face and the surface of the material being measured. This is accomplished with the use of a “coupling” fluid, commonly called “couplant”. This fluid serves to “couple”, or transfer, the ultrasonic sound waves from the transducer, into the material, and back again. -

Page 16: Changing Resolution
5.9 Changing Resolution gauge selectable display resolution, which is 0.1mm and 0.01mm. When the resolution is set to 0.01mm, the tested piece surface should be smooth to get accurate test result. When measuring rough surface or coarse grained materials, it is suggested to use low resolution. -

Note: For saving power, lower down the LCD brightness in good light environment. 5.14 Display Standby Setting Standby state lower down the LCD brightness and puts the CPU in a power conserving mode. The change from run state to standby state is controlled by the setting of the Display standby delay. -

Page 23: Appendix B Applications Notes
Appendix B Applications Notes Measuring pipe and tube When measuring a piece of pipe to determine the thickness of the pipe wall, orientation of the transducers is important. If the diameter of the pipe is larger than approximately 4 inches, measurements should be made with the transducer oriented so that the gap in the wearface is perpendicular (at right angle) to the long axis of the pipe. - Page 24 Measuring through paints and coatings are also unique, in that the velocity of the paint/ coating will be significantly different form the actual material being measured. A perfect example of this would be a mild steel pipe with approximately 0.6mm of coating on the surface. Where the velocity of the pipe is 5920m/s, and the velocity of the paint is 2300m/s.
