MEASUREMENT AND ADJUSTMENT OF A CHARGE OF A WORKPIECE

Last updated:

Abstract:

An apparatus, system, and method for managing an electrostatic charge of a workpiece are disclosed. The method comprises coupling an electrostatic voltmeter to a conductor, coupling a charge-adjustment system to the conductor, and coupling the conductor to the workpiece. A level of charge in the workpiece is adjusted, via the conductor, with the charge-adjustment circuit and a voltage of the workpiece is monitored, via the conductor, with the electrostatic voltmeter. A controller may be used to adjust the charge on the workpiece based upon the monitored voltage.
