18 The list of all parameters for aluminum
To fine-tune the instrument settings for ferromagnetic material (steel)
1.
Perform steps 1–3 of the procedure in this section on the steel standard with a
good and bad hole.
2.
Observe the following possible differences when using a ferromagnetic material
(as compared to aluminum):
— A different lift-off (probe motion) angle in the good hole
— A different notch angle in relation to the lift-off (closer to 90°)
— Lower gains in general
— Possibly identical H and V gains
An example for a steel hole is shown in Figure 5-19 on page 134. The list of all
parameters is shown in Figure 5-20 on page 134. Note that compared to the signal
for aluminum material, the impedance plane signal of ferromagnetic material has
a reverted figure.
