Refer to the figures and callout descriptions.
1. Select model wave shape (Reference, Surface, Interface).
2. Selected model appears on the graph in brown to distinguish it from the blue echo curve.
3. Click and drag cursor to move the model over the relevant part of the curve. In this example,
the Surface model is being used, therefore drag it to the part of the curve where the Surface
would be expected (to the right of the Reference).
4. The closer the model shape matches the curve shape, the lower the Objective Function value. In
the example, the brown Surface model does not match the blue curve at that position (around
570cm) so the Objective Function value is high (greater than 1).
Adjusting the Correlation algorithm based on the new model
Adjust the width, gain, attenuation parameters using FF DTM based on the surface and interface the
new model(s) data calculated using HART DTM/Field Set up Tool. Read the echo curve again as
described above to adjust the objects models further if any object is still not being read correctly.
