Investigation: the investigation was performed using a keyence vhx-5000 digital microscope.The pin is broken, but the fragment is not available for investigation.The manufacturing date is not longer comprehensible, the last maintenance of the instrument was carried out in march 2007.Deposits can be found all over the surface, caused by an insufficient reprocessing.The blade of the lower part is damaged, most likely caused by grasping a hard object.Conclusion and root cause: based on the information available as well as a result of our investigation the root cause of the failure is most probably related to an insufficient usage.Rational: in correlation with the old age of the instrument and the damaged blade, the breakage of the pin was most likely caused by high operating force during application.No capa is necessary.
