Calibration for Additional Accuracy

For additional measurement accuracy, you can perform a two point calibration while
the Corrosion Module is active. See "Calibration" on page 62 for instructions on
performing a two point calibration. Remember that the calibration must be performed
using an Olympus dual transducer.
11.9.6 Echo-to-Echo Measurements
The Echo-to-Echo function measures the distance between an echo in Gate 2 and an
echo in Gate 1. In some limited applications, you may want to measure the thickness
of a material using this function. The Echo-to-Echo function is most common when
measuring coated materials, as a measurement of the first back wall will include the
thickness of the coating. By measuring the distance between the second successive
back wall and the first, a more accurate measurement of the base material is obtained.
This allows you to ignore the coating layer.
To perform an echo-to-echo measurement
1. Use the NEXT key to navigate to the Gate2 menu item (group 2/4).
