Slide caliper assembly and method of use

slide caliper assembly comprises a caliper including a shaft defining a gaging surface. A first jaw is coupled to and a second jaw is slidably coupled to the shaft. Each jaw defines a gaging surface. One of the jaws is adjustably pivotable relative to the shaft about a pivot axis coinciding with an intersection of the gaging surface of the shaft and another axis extending along the associated gaging surface of one of the jaws. A case houses the caliper, and has a plurality of side edge sections defining a periphery of the case. One side edge section and an adjacent side edge section form a non-right angle there between such that the shaft can abut the side edge section, the first jaw can abut an adjacent side edge section, and the second jaw can abut another adjacent side edge section for calibrating or demonstrating the use of the caliper.
