After you have acquired the image, only for the first of the six steps, the operator is
requested to confirm whether the acquired sphere appears clean and free of dust
grains (refer to Figure 7-8).
Figure 7-8: Check that the calibration sphere is clean
If the operator confirms that it is clean, pressing [Yes] will cause the software to trace
the 28 mires, and the screen will appear as shown in Figure 7-9, where the operator
must verify that the reconstruction of the rings, at the edge of the mires, is complete
and lacks any exclusions.

Otherwise, if the [NO] button is pressed, you will return to the screen shown in Figure
7-6.
The message “Step 1 of 6” informs the operator of the current calibration step. The
described sequence is repeated another 5 times until the concluding message
appears (Figure 7-10).
