Page 3: Overview
Available models: TN 80-0.1US TN 230-0.1US TN 300-0.1US TN 80-0.01US TN 230-0.01US TN 300-0.01US 1 Overview Model TN- US is a digital ultrasonic thickness gauge based on the same operating principles as SONAR. The instruments are capable of measuring the thickness of various materials with an accuracy of 0.1/0.01 mm. -

2.1 Digital Display 1 Coupling status: Indicates the coupling status. While measurements are taken, the coupling status should be on. If it isn’t or if it isn’t stable, the instrument has got difficulties in achiev- ing stable measurements and the thickness value displayed will most likely be erro- neous. - Page 7 speaking, the best transducer for an operation is the one that sends sufficient ultra- sonic energy into the material to be measured in the way that a strong, stable echo is to be received in the instrument. There are several factors that affect the strength of the traveling ultrasound.

Below there are shown two photos and a short description of the instruction use of a transducer. The left figure is a bottom view of a typical transducer. The two semicircles are visibly separated in the middle of the surface. One of the semicircles is conducting the ech- oed sound back into the transducer. -

penetration of the ultrasound through the material resulted by an unstable and there- fore unreliable measurement. The surface being measured should be clean and free of any small particulate mat- ter, rust or scale. The transducer must be placed on a flat and even surface. To get it clean it might be helpful to use a wire brush or a scraper. -

5) The transducer is to be pressed flat against the surface of the control plate. Now you can see the value 4mm, because the thickness of the control plate is 4mm and the instrument is calibrated of 4mm. 6) Now the transducer is to be removed from the control plate. At this point, the instrument has successfully calculated its internal error factor and will compensate for this value in all following measurements. -

6) The and the key has to be used to adjust the displayed thickness up or down until the thickness of the sample piece is matched. 7) The key has to be pressed again. The M/S (or IN/µS) should start flashing. Now the sound velocity value, which has been calculated based on the thickness value that was entered, is displayed. -

6) The and the key have to be used to adjust the sound velocity up and down until it matches the sound velocity of the sample piece. 7) The key has to be pressed. 1OF2 will be shown on the display. Steps 3 to 6 are to be repeated on the second calibration point. -
Page 13: Change Of Measuring Sound Velocity
The responsibility for a proper use of the instrument, as well as the recognition of these types of phenomenon solely depends on the user of this instrument. 4.4.1 Change of measuring sound velocity In appendix A you find the different sound velocities, that are to be applied for meas- uring the different materials. -
Page 14: Memory Management
4.8 Memory management 4.8.1 Storing a reading There are 20 files (F00-F19) which can be used to store the measurement values inside the instrument. At most 100 records (thickness values) can be stored in each file. The measured thickness value will be saved to the current file by pressing the key after a new measurement reading appears. -
Page 15: Data Printing
4.9 Data printing At the end of the inspection process or at the end of the day, it may be required the readings being transferred to a computer. This procedure is only possible with TN xx-0.01 US, not with TN xx-0.1 US: 1. -
Page 16: System Reset
4.14 System reset key has to be pressed while powering on the instrument: factory defaults will be restored. All the memory data will be cleared during system reset. The only time this might be helpful is if the parameter in the instrument was somehow corrupted. 4.15 Connection to PC TN xx-0.01 US is equipped with a RS-232serial port. -

Some laminated materials may even exhibit noticeable changes in sound velocity across a single surface. The only way to a reliable measurement is to perform a calibration on a sample piece of known thickness.
