Echo-to-Echo Measurements
The corrosion module echo-to-echo mode measures the distance between an echo in
Gate 2 and an echo in Gate 1. Echo-to-echo measurements are most commonly used to
determine the thickness of coated materials, since the first back wall measurement
includes the thickness of the coating. Measuring the distance between the second
successive back wall and the first back wall provides a more accurate measurement of
the base material, so you can ignore the coating layer.
