    Abstract: A method for testing a conductive web includes moving a conductive web past at least one electrostatic probe, providing an alternating current or voltage which generates an alternating current to the at least one electrostatic probe, measuring a current or voltage in the at least one electrostatic probe induced by a capacitance between the conductive web and the at least one electrostatic probe, comparing the measured current or voltage to a reference value, and determining a level of bagginess of the conductive web based on the step of comparing.
