Verification
Verification process is the opportunity to test the analytic with the assigned
tracking region. It is best practice to rotate the engine to present at least three
blade aerofoils through the tracking region to ensure successful operation
during the actual visual examination.
There is no upper limit to the number of blades to include during this step.
It is possible to view the count of aerofoils detected during this verification
stage. See information presented within the blue banner located at the top
of the screen (Figure 5).
Figure 5. Showing the banner message associated with blade counting during verification.
Ensure the count coincides with the true number of blades passing through
the tracking region and more specifically the trigger point.
Stop engine rotation after at least three blades have been rotated.
Now press 'Complete Verification' softkey and answer the following question
presented in Figure 6.

Fig 6. Did you rotate 'x' blades?
If NO, then press that softkey and proceed.
If Yes, then press that softkey and follow next steps.
Before starting the visual inspection, it is now possible to:
• Enter the total number of blades in that stage. This function enables the
counter to return to blade number 1 at the appropriate point to ensure
a complete revolution had been performed (Figure 7a). Maximum limit
is 999 blades.
• Enter the blade number upon which the inspection begins (Figure 7b).
