wall echoes. Therefore, a good usage of the E-E option is for measuring
through coatings (Max. 2mm) to measure only the true metal thickness.

8.5.1 Velocity rate
Sound velocity played an important role in measurement. Different
material is of different sound velocity. When the sound velocity is
incorrect, it will cause wrong measured results. There are two ways to
select the material's sound velocity, which are Velocity selection and
Velocity measurement.
8.5.1.1 Materials
The gauge gives the sound velocity of 9 different materials which can be
select by yourself. The 9 materials are: aluminum, titanium, steel, stainless
steel, glass, copper, brass, polystyrene, cast iron.

Press
to confirm.
Notice: the 9 values are just the theoretic values, if users want to get
accurate measurements , please refer to the” Velocity measurement”
and get the more accurate sound velocity.
8.5.1.2 Velocity input
When the sound velocity of 9 materials is not satisfied with the
requirements of the users, there is a sound velocity table which gives the
sound velocity of various materials in the appendix. Use this table to set
the correct sound velocity. The usage is as follows:
