To measure thicknesses
1. Apply couplant to the test block or tested part at the measuring spot.
In general, use a thinner couplant such as propylene glycol, glycerin, or water for
smooth material surfaces. Rough surfaces require a more viscous couplant such as gel
or grease. Special couplants are required for high temperature applications.
2. Using moderate to firm pressure, couple the tip of the transducer to the surface of
the test material, and keep the transducer as flat as possible on the material
surface (see Figure 5-9 on page 76).

3. Read the measured thickness value for the tested part.
