Setting The Sound Velocity - GE DMS Go+ Operating Manual

Carrying out the calibration

Setting the sound velocity

If the sound velocity in the test object is known, you can
also set it directly without applying one of the calibration
methods using a calibration block.
You can find a list of typical sound velocities in different
materials in chapter 10 of this manual (see Section
Sound velocities, page 10-4).
N o t e
It is recommended to verify the velocity set-
ting by means of an object with known thick-
ness which is made of the same material as
the test object.
