Abstract
A method for self-testing a dual-mass linear accelerometer in which a self-test voltage is applied to urge the two masses to move in opposite directions. Self-test signals are then applied to obtain a differential mode signal to detect masses repositioned in opposing directions. During testing, common disturbances to the two masses are rejected as common mode signals.
