Abstract : Deficiencies possibly resulting from excessive speed under normal field operating conditions, were observed on the M15 Elevation Quadrant Counter. Therefore, a program to experimentally measure maximum speeds of the counter shaft was undertaken. Results of the investigation indicated that revolutions per minute attained were extremely high for the type of counter used. Several recommendations are made concerning continued investigations on the counter. (Author)
