Tools for measuring electrometer dispenser response

摘要

An apparatus is provided for determining the response of an electrometer used in an electrophotographic recording apparatus. The apparatus includes a movable base disposed adjacent said electrometer. The base includes a non-conductive material. A conductive pattern is disposed on the base. The conductive pattern is electrically connected to a variable power supply. A motor moves or drives the base past the electrometer. The motor is controlled by a motor control to vary the speed of movement of said base. A method is also provided for determining the response of an electrometer used in an electrophotographic recording apparatus. An electrometer to be tested is selected and the operational parameters of the electrometer are dynamically tested.
