Six-Position Testing of MEMS Accelerometer

A six-position testing method of MEMS accelerometer is introduced mainly.According to the error model of MEMS accelerometer the scale factor of MEMS accelerometer,bias of MEMS accelerometer and error on installation of MEMS accelerometer are derived.When the user gets these parameters,the user should pack the function of the concrete mathematics model in C code.By analyzing the results of examination,the six-position testing method of MEMS accelerometer is simple on principle,easy to realize and high in precision as long as the user gets the error model of MEMS accelerometer.And the scale factor nonlinearity is improved by the error model of MEMS accelerometer.
