2.5.2 TS1–TS2–TS3–TS4 Calibration

  1. Apply a known temperature in 0.1°C, and verify that temperature TEMPTSx is applied to the thermistor connected to the TSx pin. "TSx" refers to TS1, TS2, TS3, or TS4, whichever is applicable.
  2. Read the TSx offsetold from External x Temp Offset, where x is 1, 2 ,3, or 4.
  3. Read the appropriate temperature from the DAStatus2() block as TSx.
  4. Calculate the temperature offset:
    Equation 6. T S x   o f f s e t   =   T E M P T S X -   T S x   +   T S x   o f f s e t o l d

    Where x is 1, 2, 3, or 4.

  5. Write the new External x Temp Offset (where x is 1, 2, 3, or 4) value to data flash.
  6. Re-check the DAStatus2() reading. If the reading is not accurate, repeat steps 1 – 5.
