General description
1.1 Scope of applications
The handheld microprocessor-controlled thickness gauge is designed for
measuring the thickness of metals, and non-metallic materials e.g. aluminum,
titanium, plastics, ceramics, glass and any other good ultrasonic wave-conductor
as far as it has two parallel surfaces on the top and bottom.
The TT100 can be used in industrial applications to perform precise
measurements on various kinds of new materials, parts and components, and it
can also be used to monitor various kinds of pipes and pressure vessels for the
decrease of their thickness due to corrosion and/or erosion.
1.2 Basic working principle
The principle of ultrasonic wave in the thickness measurement is similar to that of
optical wave. The ultrasonic wave pulses transmitted by the probe will be reflected
back, while they reach the interfaces. The thickness of the object is determined by
precisely measuring the time the ultrasonic wave travels in the object.
1.3 Basic configuration and each part description of the tester
1.3.1 Basic configuration:
main processor: 1 piece

Push On-key to turn on the unit. As it is shown in the figures below, after the full screen display for a few seconds, the screen will display the sound velocity used last time. The measurement can start now, but read other paragraphs first. - Page 5 The screen will display the content of the current memory unit of sound velocity. Each time the VEL-key is pushed the sound velocity memory unit will change. Five different sound velocity values will be displayed in turn.

This indicates that the calibration is over: 4.4 Calibration to a known velocity: thickness measurement Put the coupling agent in the place to be measured.

Page 8: Maintenance
While measuring the thickness, the value measured will be stored in the chosen unit automatically. Each time a new value is measured, the old value in this unit will be automatically replaced. U1 >> Push the VEL-key once more to leave the thickness memory state. - Page 9 Grease, oil and dust will make the cable of the probe aged and cracked, therefore, after the use, the cable should be cleaned of dust and dirt. If the unit is not to be used for a long time, remove the batteries. Strictly avoid any collision or damp environment, etc.
