Page 3: Overview
1 Overview The model MT150/MT160 is a digital 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. It is suitable for a variety of metallic and non-metallic materials. -

Selection of the proper transducer is often a matter of tradeoffs between various characteristics. It may be necessary to experiment with a variety of transducers in order to find one that works well for a given job.

Page 8: Condition And Preparation Of Surfaces
3.2 Condition and Preparation of Surfaces In any ultrasonic measurement scenario, the shape and roughness of the test surface are of paramount importance. Rough, uneven surfaces may limit the penetration of ultrasound through the material, and result in unstable, and therefore unreliable, measurements. The surface being measured should be clean, and free of any small particulate matter, rust, or scale. -
Page 9: Sound Velocity Calibration
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. -
Page 10: Making Measurements
Press the key again, so that The M/S (or IN/μS) symbols are flashing. Use the key and the key to adjust the sound velocity value up or down, until it matches the sound velocity of the material to be measured. You can also press the key to switch among the preset commonly using velocities. -

4.6 Changing Resolution MT160 has selectable display resolution, which is 0.1mm and 0.01mm. This function is not available for MT150, which is fixed to 0.1mm. Press down the key while turning on the gauge will switch the resolution between “High” and “Low”. -
Page 12: Memory Management
At the end of the inspection process, or end of the day, the user may require the readings be transferred to a computer. The following steps outline this procedure. This function is only available for MT160, and not for MT150. Before printing, please insert one connection plug of the print cable (Optional parts) into the socket on the up-left of the main body, and insert the other plug into the communication socket of the mini-printer. -
Page 13: Beep Mode
Use the key and the key to select the desired file. Press the key to print the selected file. This operation will send all the data in current file to the mini printer via RS232 port and print them out. -

As materials heat up, the velocity of sound through them decreases. In most applications with surface temperatures less than about 100 ℃...
- Page 16 A wide variety of couplant materials may be used in ultrasonic gauging. Propylene glycol is suitable for most applications. In difficult applications where maximum transfer of sound energy is required, glycerin is recommended. However, on some metals glycerin can promote corrosion by means of water absorption and thus may be undesirable.
