Abstract
A system for measuring the conductivity of a flexible media positioned between a conductive backing and a conductive roller, wherein the conductive roller contacts the flexible media in a roller contact region. A pressure control mechanism presses the conductive roller against the second surface of the flexible media with a specified contact pressure, and a motion control system provide a relative motion between the conductive roller and the flexible media. A resistance measuring system connected to the conductive roller and the conductive backing measures the conductivity of the flexible media within the roller contact region. A data recording system records the measured conductivity of the media as a function of position.
