Sound velocity of the instrument
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 material selection and sound
velocity setting.

Material selection
If the material and its sound velocity is known, users can select a sound
velocity which is almost that of the standard material. The material options
give the sound velocity of 9 different materials which can be select by
yourself.
Note: the 9 values are just the theriotic values, if users want to get
accuret measuremnts , please refer to the sound velictiy function and get
he more accurate sound velocity.
The 9 materials are: aluminum, titanium, steel, stainless steel, glass,
copper, brass, polystyrene and nylon.
