Page 4: General Information
General information The model TO-EE is an ultrasonic material thickness gauge with several operating modes. Based on the same operating principles as SONAR, the instrument can measure the thickness of various materials with an accuracy of down to 0.1 / 0.01 millimetres. - Page 5 3.0 ~ 300.0 mm for thick, strongly (in steel) weakening 20 mm strongly scattering 40 mm (in grey cast materials iron HT200) Φ 20 mm × 1 ~ 600.0 mm Normal 3,0 mm measurement (in steel) Φ 20 mm × 1 ~ 600.0 mm Normal N05/90°...

2.2 Control panel The design of the device allows the user quick access to all device functions. A user- friendly menu system allows access to any function by pressing a few keys. Function keys for selecting the desired function on the display. In the following sections of this manual they are referred to as F1, F2 and F3, from left to right. - Page 9 • Absorption and scattering: If the ultrasound propagates through any material, it is partially absorbed. If the material through which the sound propagates has a grain structure, the sound waves are scattered. These two effects reduce the strength of the waves and thus the ability of the instrument to detect the returning echo.

The left figure shows a typical transducer from below. The two semicircles of the contact surface are visible, as is the barrier separating them. One of the semicircles is responsible for propagating ultrasound in the material to be measured and the other semicircle is responsible for returning the echo to the transducer. -

To turn off the instrument, press and hold the button until the shutdown message appears. The meter also has an automatic power-off function to save battery capacity. If there is no operation for a certain period of time (set as automatic power-off delay), the meter will automatically turn off. -
Page 13: Operation
5 Operation 5.1 Setting the working mode Users and inspectors often deal with coated materials such as pipes and tanks on site. Typically, inspectors must remove the paint or coating prior to measurement or take into account a certain number of defects caused by paint or coating thickness or speed. The error can be eliminated with this meter by using a special echo-echo mode designed for measurements in such cases. -

4. Press the transducer against the probe plate and make sure that the transducer is flat against the surface. 5. When the progress bar is complete, remove the transducer from the probe plate. Repeat this procedure four times if necessary. 6. - Page 15 Note: One or two-point calibration must be performed on a material after the removal of paint or coating. Otherwise, it will result in a calculation of the material speed that is different from the actual material speed of the material to be measured. 5.4.1 Calibration to known speed Note: This procedure requires a sample of the specified material to be measured, the exact thickness of which is known, e.g.
- Page 16 5.4.3 Two-point calibration Note: This method requires two known thickness points on the test piece, which are representative for the range to be measured. 1. The "Probe Zero" function must first be performed on the standard plate of the instrument. 2.

Figure below: Measuring the second point during two-point calibration. 7. Repeat steps 2 to 6 at the second calibration point. 8. Finally, press the / F3 key to complete the two-point calibration. The meter is now ready to take measurements within this range. 5.5 perform measurements When the instrument displays thickness measurements, the display shows the last measured value stored until a new measurement is performed. -

Note: When removing the transducer, a thin film of coupling agent is occasionally drawn between the transducer and the surface. If this is the case, the measurement is made through this film of coupling agent, resulting in a reading that is greater or less than it should be. -

Diff Mode. Both the last thickness reading and the differential thickness value are displayed (of the absolute thickness value and the nominal thickness value). Although the gauge is excellent for single point measurements, it is sometimes advisable to examine a larger area and search for the point with the smallest thickness. The gauge has a "Scan Mode"... -

Page 29: Instructions For Use
10 Instructions for use 10.1 Measurement of large and small pipes When measuring a pipe section to determine the thickness of the pipe wall, the alignment of the transducers is important. If the pipe diameter is larger than approx. 4 inches, the measurements should be carried out with the transducer arranged so that the gap of the contact surface is perpendicular (at right angles) to the longitudinal axis of the pipe. -
Page 30: Measuring Of Laminate Materials
10.3 Measuring of laminate materials Laminate materials are unique in that their density (and thus the speed of sound propagation) can vary considerably from one piece to another. Some laminate materials can even show significant variations in the speed of sound on a single surface. -
Page 31: Coupling Agents
10.6 Coupling agent All ultrasonic applications require a medium to couple the sound from the transducer to the specimen. Normally a liquid with high viscosity is used as medium. The propagation in air of the sound used for ultrasonic thickness measurement is ineffective.
