ABSTRACT:
An apparatus for obtaining measurements of the charge on a surface of a member during a period of time while applying a charge to the surface of the member is provided. The apparatus includes a frame. The member is rotatably secured to the frame. The apparatus also includes a charging device for applying the charge to the member. The charging device includes a charging device portion thereof positioned proximate to an external periphery of the member. The apparatus also includes a mechanism for rotating the member. The mechanism is operably associated with the frame. The apparatus also includes a charge measuring device operably associated with the support for measuring an electrical field emanating from the member. The charge measuring device includes a measuring device portion thereof positioned proximate to a measured position on an external periphery of the member. The mechanism is cooperable with the member to rotate the member. The charge measuring device is adapted to measure a charge at the measured position after the member is so rotated.
