Y.
Coefficient for Linearity Correction [Address Number: 172, 173, 174, 175, 176, 177, 178, 179]
Parameter to correct the linearity error of output against the solar irradiance [k1, k2, k3, k4]
*Linearity correction is not setup in default setting. Do not change this value.
If linearity compensation is necessary, refer to the following compensation formula:
