During test, it should be noted that the metal magnetism and surface roughness of the standard piece should be similar to the test piece. 2. Keep the side head perpendicular to the surface of the sample during measurement. 3. Pay attention to the critical thickness of the base metal when measuring. If it is greater than this thickness, the measurement will not be affected by the thickness of the base metal.
