ABSTRACT: This is the user guide for the Maury Microwave model A050A Connector Gage Kits (2.92mm and 3.5 mm digital, metrology grade). The Maury model A050A connector gage kit is designed to measure 2.92/3.5mm connectors with either female or male interfaces. The digital indicators used in the A050A connector gage kit provide a measurement resolution of .0001” when used in the inch mode or .001mm (0.000040 inches) when used in the metric mode. For simplicity, the rest of this manual will refer to measuring in inches. However, the principles presented apply equally when used in metric mode. The Maury A050A connector gage kit achieves excellent repeatability by maintaining tightly controlled tolerances on all machined parts. To achieve maximum accuracy, Maury recommends that an average of 3 measurements taken at different gage orientations be used to minimize random errors.
