<strong>Calibration</strong> <strong>Kits</strong>12INTERFACE GAUGES: Checking the interfaces of connectors and adapters upon incominginspection is not only highly recommended, it is definitely a necessity. Interfaces not meetingspecification will not only lead to degraded specification of the components, furthermorethese out of specification interfaces may damage the connectors of mating components orruin the connectors of test equipment. Connector Gauges consist of an especially adapted dialindicator with appropriate bushings and pins that are designed to mate with the specificconnector under test. The indicator of each gauge is zero set by a specific master gauge.Whenengaged to a connector, it measures the specific interface dimension from a reference plane.For every dimension of interest, a special gauge will be offered. This gives the most accurateresults, allows easy calibration, fast testing and helps to avoid mistakes. Gauges are availableas “Hand Held” or “Thread On”. Faster testing is possible by using the “Hand Held” gauges,the more accurate readings will be achieved from the “Thread On” gauges, as threading onthe gauges will perfectly align with the connector. Hand Held means aligning gauge andconnector freely, which may allow for mistakes.TORQUE WRENCHES: Connectors have to be mated and need to be tightened. Peoplewho are using nothing but their fingers for tightening, usually undertorque. The electricalperformance will vary from tightening to tightening, depending how tired the fingers are. Inaddition: If the same component gets tested several times and by different people, using fortightening nothing but their fingers, the electrical performance will even vary more, as differenttorque will be applied, equivalent to the strength of the individual. But the strength doesnot only depend on the physical ability of the individual, furthermore also to the strength setby the mind. Tightening connectors by hand will result from very loose fits to almost correctfits, but usually always incorrect fits. Tightening connectors by hand is obviously inadequateand not recommendable. People who are using a regular wrench, usually overtorque. Shortwrenches may lead to torsional forces that are only a little high, the use of longer wrencheshowever usually results into applying very high torque. Overtorquing of up to three times hasbeen seen. This will deform the interface of the connectors, proper test results from then oncannot be obtained anymore. For proper test results and long life of the connectors the rulesneed to be obeyed. For each individual connector series a torque has been specified, a torquethat ensures proper mating conditions, repeatable electrical performance and guarantees mechanicallya long life of the connectors. Using the Torque Wrench guarantees that the connectionis not too loose, it also ensures that the connection is not too tight, preventing possibleconnector damage and impaired electrical performance. Using the Torque Wrench also assuresthat all connections are equally tight, each time. No connection at a network analyzer, duringcalibration and testing of components, should be made without using the proper torque wrench.THREAD LIMIT GAUGES: Out of limits thread on connectors and adapters can createserious problems and may damage the connectors of mating components or ruin theconnectors at the test equipment. <strong>Spectrum</strong> <strong>Elektrotechnik</strong> <strong>GmbH</strong> offers therefore a comprehensiveline of thread limit gauges to check the thread on a “GO” / “NO GO” basis.The pitch diameter, pitch angle and number of threads per unit are being examined. Acomplete Set of gauges consists of two Ring Gauges and one Bolt Gauge.<strong>Spectrum</strong> <strong>Elektrotechnik</strong> <strong>GmbH</strong> P.O. Box 45 05 33, 80905 Munich, Germany Tel.
