Jig for calibration of measuring instrument and measuring instrument calibration system using the same jig

PURPOSE: A jig for calibration of a measuring instrument and a measuring instrument calibration system using the same are provided to improve calibration accuracy because a location detection sensor of an IGPS(Intelligent Global Positioning System) is settled in a sensor mounting hole of an upper block unit by a magnet. CONSTITUTION: A jig for calibration of a measuring instrument comprises a block body and a target sheet(300). A location detection sensor of a IGPS for calibrating errors of a measuring instrument is coupled to a sensor mounting hole(110) of the block body. The target sheet is coupled to the block body.
