Abstract
A force measurement apparatus that provides means to compensate for thermal or other disturbances. The apparatus utilizes non-contact electron transfer mechanisms to provide indications of force sensed on a test mass. A plurality of electrodes are used in a differential measurement mode to provide self-zeroing and distortion compensation.
