3.3.3 Calculation Example (Continued for Frequency Compensation)

Given that Coriginal = 6062, Cnew = 6175, FREQ_SLP1original = -92, and FREQSLP2original = -374, begin by calculating the original error percentage used in frequency compensation:

Equation 27. ErrorFS1=-920.01×(6062-18687.13)=0.729%
Equation 28. ErrorFS2=-3740.01×(6062-92-18687.13)=2.94%

Then use those percentages to calculate the new frequency compensation register values:

Equation 29. FREQSLP1new=0.01×6175-18687.13×0.729%=-91
Equation 30. FREQSLP2new=0.01×6175-91-18687.13×2.94=-371

The same calculations are repeated for the secondary sensor using the original register values.
