ABSTRACT:
System and method for mitigating errors in electrostatic force balanced instrument is provided. The system and method mitigate errors in measurement readings caused by charge buildup in force balanced instruments that employ charge pulses to generate an electrostatic force to null an inertial proof mass disposed between opposing electrodes. The system and method mitigate charge buildup by applying charge pulses to each opposing electrode of a sensing element for a given charge cycle time period in a normal polarity configuration followed by charge pulses to each opposing electrode of the sensing element for a second given charge cycle time period in a reverse polarity configuration.
