2.5.1 Internal Temperature Sensor Calibration

  1. Apply a known temperature in 0.1°C, and verify that temperature TempTINT is applied to the device.
  2. Read the TINT offsetold from Internal Temp Offset.
  3. Read the reported temperature from DAStatus2():
    • TINT = AAaa of DAStatus2()Is TINT > 0? If yes, TINT = AAaa – 2732.
  4. Calculate temperature offset:
    Equation 5. T I N T   o f f s e t   =   T E M P T I N T   -   T I N T   +   T I N T   o f f s e t o l d
  5. Write the new Internal Temp Offset value to data flash.
  6. Re-check the DAStatus2() reading. If the reading is not accurate, repeat steps 1 – 5.
