The same applies when the depth of holes and cracks is measured.3.4.2 Shiny surfacesWith shiny surfaces, it is important to ensure that the direct reflection does not strike the receiver. This can beprevented by tilting the sensor slightly. To check this, place a sheet of white paper on the disc of the receiver;the direct reflection can then be seen clearly.3.4.3 Round, shiny surfacesWith round, shiny surfaces, the sensor should be aligned in the same axis as the round object in order toavoid reflections.
