How cables and connectors impact measurement uncertainty

April 27, 2006
This application note presents information meant to help minimize uncertainty due to choosing the wrong cable for the setup, inappropriate connections, or problems caused by inadequate preventative maintenance.

MORE OFTEN than perhaps known, the outcome of a calibration procedure can depend on the technician knowing which cables and connectors are appropriate for the calibration setup. Choosing the wrong cables and/or connectors can have a significant impact on the overall uncertainty of the setup or calibration system. If you’re new to DC and low-frequency AC calibration, it’s important to understand the impact connectors and cables have on overall measurement uncertainty, as well as the importance of cable maintenance.

There are many factors that affect measurements that are not necessarily pointed out in calibration procedures. It is the knowledge and skill of the technician performing the measurement that impacts the overall uncertainty of a measurement.
