Failed Verification
It is possible for the analytic to mis-count aerofoils during verification. Some or all blades may not be detected due to insufficient contrast between the
blade edge and the background scene. Alternatively, the Blade Counter may trigger unexpectedly if other edges are detected within the tracking region.
Because of this, it is important to press the ‘No’ softkey (shown below) and re-attempt blade counter setup.
If verifcation has failed, please try one of the following:
• Re-assign the lines to a different position within the given FoV that presents a greater contrast.
• Press the ‘Sensitivity: low’ softkey to activate a function to increase the analytics ability to detect lower contrast threshold limits.
Note:
‘Sensitivity:
low' setting is the recommended default. Note – it is not possible to adjust this setting post-verification
• Re-adjust the probe to an alternative viewpoint in order to achieve greater contrast of the blade edge.
• Adjust the illumination or brightness setting.
