What is the difference between calibration and normalization?� Calibration
– Uses a discreet point or defect that affects only a small number of probe coils to set inspection parameters.
– Sets all coil values to the same values as the values of the coils that detect the defect.
� Normalization– Uses a uniform defect
that affects all probe coils to set inspection parameters.
– Ensures that all coils respond the same way to the same defect.
