Apply the couplant evenly to the tested area, tightly couple the
probe to the surface of the tested material, and the screen will
display the thickness of the tested area. When the probe and
the material to be tested are well coupled, the screen will display
the coupling mark . If the coupling mark flashes or there is no
coupling mark, it means that the coupling is not good and needs
to be added with couplant. When the probe is removed, the
coupling symbol disappears and the thickness value remains.
