Rem --> Determine minimizing C by calculating average epsilon
epsilon_sum = 0
C = 1
For T = T_min To T_max Step T_step
epsilon_sum = epsilon_sum + epsilon(T)
Next
epsilon_mean = (epsilon_sum / n)
C = epsilon_mean + 1
Rem =============================================================
Rem --> Determine epsilon sum
epsilon_sum = 0
For T = T_min To T_max Step T_step
epsilon_sum = epsilon_sum + epsilon(T) ^ 2
Next
epsilon_rms = Math.Sqr(epsilon_sum / n)
Rem =============================================================
Rem --> Determine if new optimum parameters were found
If epsilon_rms < epsilon_rms_opt Then
epsilon_rms_opt = epsilon_rms
TL_opt = TL
TQ_opt = TQ
End If

Rem =========================================================================
Rem --> Finally retrieve the best TL, TQ values stored during the sweep
TL_final = TL_opt
TQ_final = TQ_opt
After the iteration is complete, the values TL
values shall be programmed into the sensor's EEPROM.
