Abstract : The procedures for calibrating a precision leadscrew type comparator are described and the results of the calibration of the ballistic plate comparators in use at AMR are given. The errors to be calibrated are: (1) periodic leadscrew error, (2) scale error and secular leadscrew error, (3) weave and curvature of the ways and (4) nonperpendicularity of axes. The standard error of the plate coordinates obtained from Mann comparators 422C66 and 422D49 and Wild/Stereo Comparator STK-1 were reduced from 2.2, 4.9 and 5.2 microns to 1.2, 1.2 and 1.9 microns, respectively as a result of the calibrations.
