Abstract
A method for reducing bias drift in electrical-mechanical systems sensor such as an accelerometer is provided. The method includes the steps of arranging at least one accelerometer in a chamber and initiating a plurality of temperature cycle sets. Each temperature cycle set has a minimum temperature, a maximum temperature, and a ramp rate. The conditioning method monitors the accelerometers until a bias drift is stabilized within a desired bias drift range. The minimum temperature and the maximum temperature limit a temperature range in which the accelerometer is cycled. Use of temperature limiting can quickly accelerate stabilization of the bias drift while also reducing degradation.
