[Cause]
iRCalibration 's visual measurement error. The target rotation angle exceeds the "rotation angle range" set in the Visual Settings image.
[Countermeasure]
The response is through the following steps.
・To confirm whether the target rotation angle in the starting position of the measurements matches the model. If the target rotation angle does not match the model, the target phase angle (sets) is changed or the model is reteached.
・ If the above countermeasures are ineffective, check that the measurement posture is correct, then expand ‘Rotation angle range’.
