Page 4: General Information
A1207 and A1207C are small hand-held Ultrasonic Echo-pulse Thickness Gauges in a form of marker-pen, designed for general thickness measurements. A1207C is a special version of A1207 that is equipped with single crystal probe (“C” in the end of the marking means ‘single crystal probe’). -
Page 5: Description
A1207C version is equipped with single crystal probe on 2,5 MHz operating frequency and with 10 mm operating surface diameter. The structure of A1207 and A1207C allows replacing the probe’s capsule in case of Acoustic Control Systems, Ltd. Moscow, 2006... - Page 6 ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) wearing. This replacement can be made by the operator himself and is described in the item 7.3 of this manual. The digital light-emitting diode display makes possible the application of the device in a wide range of temperatures (from -30°C up to +50°C).

Page 9: Measurements And Adjustment Of Device
For that you need to use the steel testing sample block that is in the basic set of the device. To test the device (both A1207 and A1207C) you need to do the following: Press the On button. Acoustic Control Systems, Ltd. - Page 10 ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) On the screen you will see horizontal strokes. With the help of Velocity choice buttons set the ultrasound velocity for the control steel sample block. Put the device on the control block and hold for 1- 2 seconds, until the reading stops changing on the display.

On the screen you will see the horizontal strokes. With the help of Velocity Choice button choose the rarely used meaning of ultrasound velocity, that can be changed (for ex. 5400 m/s) Put the device on the sample block.
- Page 15 ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) Change the ultrasound velocity in the device. Put the device on the sample block and compare the real thickness with the readings of the device. If it is necessary you will need to repeat these actions until the device shows the same thickness of the sample block as it’s real thickness is.

Page 18: Principles Of Operation
ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) PRINCIPLES OF OPERATION A1207 and A1207C operate on the ultrasonic pulse-echo principle. The device measures the time of double travels of ultrasonic oscillations through the material from one surface to another. This time is recalculated to the meaning of thickness. -
Page 19: Some Notes On Operation
Electro-acoustic screen (that is the line on the operating surface of the probe) in A1207 should be directed perpendicular to the tube’s axle. Pressing the probe to the tube’s surface and watching the readings of the device, you need to lean the probe from side to side in the plane perpendicular to the tube’s axle. - Page 20 ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) Acoustic characteristics of material. Some characteristics of constructive materials can essentially limit the exactness of measurement and range of measured thickness. 1. Sound dispersion In some materials (for example, some types of stainless steel, cast-iron, composites) the sound energy is dispersing (on crystallite moulding or on additions in composites).

ULTRASONIC THICKNESS GAUGE - A1207 (A1207C) After that leave the velocity choice button. On the display you will see horizontal strokes. In 1-2 seconds they should blink, and that will mean that the device is ready for work. 7.3. REPLACEMENT OF THE PROBE’S CAPSULE When the probe’s capsule is worn out it is possible to replace it. - Page 23 After you have replaced the probe’s capsule you need to check the exactness of measurement on the testing samples. A1207 is tested on the testing samples with known ultrasound velocity in them with the thickness of 0,8 – 30 mm. The A1207C version is tested on the samples of 10 –...
