Includes offset deviation from 0g value including calibration error and drift over lifetime, temperature and supply voltage. Includes offset deviation from 0g value including calibration error and drift over lifetime. 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. Biggest change of output from RT value due temperature.
