A method and apparatus to verify that proper tooling has been installed in a cable preparation apparatus and/or to calibrate the tooling prior to running the cable preparation apparatus with a cable inserted therein. The method includes: inserting a reference device between blades of the cable preparation device; moving the blades inward toward the reference device until the blades engage the reference device; collecting data to determine when the blades engage the reference device; and comparing the collected data of the blades to an expected range of data of the reference device, wherein if the collected data of the blades does not conform to the expected range of data of the reference device the tooling is not validated, and the apparatus alerts the user.

A cutting unit for thermoplastic pipes includes a ring rotating about an axis and in which a pipe is progressively moved in a sliding fashion such that a longitudinal axis of the pipe coincides with said axis of rotation and a cutting arm mounted on the ring. A distance measurement sensor located on the ring is configured for acquiring, during rotation of the ring, values representing a radial distance between the measurement sensor and an outer surface of the pipe. The distance is measured on a measurement plane transversal to the axis of rotation. The cutting unit also includes a processing and control unit operatively connected to the measurement sensor and configured for receiving the values measured and for calculating, on the basis of the values, at least one parameter representing a peripheral profile of the pipe on the measurement plane.
