B) Includes offset deviation from 0g value including calibration error and drift over lifetime, temperature and supply voltage. C) After mounting of ECU the application and after offset zero-setting at room temperature. Relevant offset failure due to temperature dependency of offset as well as aging over lifetime D) Includes offset deviation from 0g value including calibration error and drift over lifetime. E) Offset drift due to temperature. Value is a relative value and has been centered to zero. Error defined as maximum change of offset in temperature range. Offset (max)-Offset Min). 100% tested in production. F) Biggest change of output from RT value due temperature.
