ABSTRACT:
A calibration tool comprises two relatively movable elements. A compression spring is operatively positoned between the first and second elements for resisting closure of the elements with respect to each other. Displacement of the first element is determined with respect to the second element when the spring is compressed by a predetermined pressure. A connecting element, such as a band, is coupled to the calibration tool and to the tensioning apparatus such that actuation of the tensioning apparatus causes the band to effect relative movement of the first and second elements whereby the force exerted by the tensioning apparatus is determined.
