A pulse-width-modulated signal provides inherently linear electrostatic force feedback for application in gravity meters. Previous methods were linearized through the use of dual-force rebalance plates and careful adjustment. The suggested system works equally well with single- and dual-plate systems and requires no adjustment. Although dial-setting errors and noise limit individual observations to a few microGals, a calibration accuracy of 0.25% was achieved. A careful analysis of residuals after regression analysis revealed no evidence of nonlinearity.
