    • An electric-field meter provided with a housing, an electrode assembly, a shield assembly, a movement assembly, a position detection assembly, a charge measurement circuit, and a leakage current compensation circuit. The electric-field meter can be characterized as a field mill, an induction voltmeter, an electrostatic fluxmeter or an agrimeter. The electrode assembly is selectively exposed to the electric field. The shield assembly alternately covers and exposes the electrode assembly to the electric field. The movement assembly has a source of motive force and a linkage operably connected to one of the shield assembly and the electrode assembly for alternately covering and exposing the electrode assembly to the electric field. The charge measurement circuit receives charge on the electrode assembly. The charge measurement circuit provides a charge detection signal indicative of the charge induced on the electrode assembly as the electrode assembly is selectively exposed to the electric field. A current compensation circuit is provided for offsetting an average leakage current at the input of the charge measurement circuit.
    • 具有壳体,电极组件,屏蔽组件,移动组件,位置检测组件,电荷测量电路和泄漏电流补偿电路的电场仪表。 电场表可以表征为现场研磨机,感应电压表,静电通量计或农用扫描仪。 电极组件选择性地暴露于电场。 屏蔽组件交替地将电极组件覆盖并暴露于电场。 运动组件具有动力源和可操作地连接到屏蔽组件和电极组件中的一个的连接件,用于交替地将电极组件覆盖并暴露于电场。 电荷测量电路在电极组件上接收电荷。 当电极组件选择性地暴露于电场时,电荷测量电路提供指示在电极组件上感应的电荷的电荷检测信号。 提供电流补偿电路用于抵消在电荷测量电路的输入处的平均漏电流。
