ELECTROMETER APPARATUS FOR REPRODUCTION MACHINES ABSTRACT OF THE DISCLOSURE Apparatus to enable potentials applied to various operating components of an electrostatic type reproduction machine to be measured by an electrostatic voltmeter. In one embodiment, the apparatus comprises structures design- ed to place the sensing element of the voltmeter in pre- determined spaced relationship with a test plate, the test plate being electrically connectable to the source of potential to be measured. In another embodiment, the apparatus locates the voltmeter sensing element in pre- determined spaced relation with both the reproduction machine photoreceptor and the test plate. As a further alternative, a source of calibrating potential is provided for use in calibrating the voltmeter through the test plate.
