Takeover Of Sound Velocity To The Instrument; Measurement With The Td Special Gold; Interpretation Of The Measured Value - sauter TD GOLD 40 Instruction Manual

Please click into the line „new component". Here please now select the first compo-
nent of the composition – other than gold – and define the share of mass in percent
of the composition. The software now adds automatically the relevant mass.
After adding all components, the software shows the exact and individual sound ve-
locity of the test object.
This individual sound velocity is to be set into the SAUTER TD Ultrasound instru-
ment.

8 Takeover of sound velocity to the instrument

Please turn the instrument on. Then please press the VEL key. Now a sound velocity
appears, e.g. 5000 m/s. By pressing the arrow keys ▲ and ▼the sound velocity can
the changed in 10 m/s steps. Please round the calculated sound velocity accordingly.
By pressing VEL again, this setting is stored.

Measurement with the TD special gold

Please put a little bit coupling gel (ATB-US 03, can be reordered) onto the test object.
Place the sensor on the gel, gently pressed by hand. The sensor has to be connect-
ed with the TD display unit.
If the connection is fine, in the display can now be seen:
((●)) This symbol shows the successful coupling. This
means, that the ultra sound travels regularly
through the material, is reflected and captured
with its echo.
Value (mm) This number indicates the thickness in mm
of the test object

10 Interpretation of the measured value

The measured value of the TD ultrasound instrument shall be within the tolerances
calculated by the SSG software.
