Correction-factor for the Cp-calculation. The Cp-value = calculated Cp * correction-factor
O2%-Offset
Corrective offset for O2%.
O2ppm-Offset
Corrective offset for O2ppm.
LogO2-Offset
Corrective offset for LogO2.
Attention! The corrective offsets for the different representations of the O2 partial pressure are inde-
pendent from each other. If all three O2-oOffsets are not 0, is not guaranteed that the representation-
forms are consistent among each other!
K1, K2,
The calculation of the C-potential with application of a lambda probe (result Cpl) , uses beside the the
CO-value the coefficients K1 and K2. Default values are:
K1
907.0
K2 0.2145
By means of these coefficients, corrections can be made for the calculation of Cpl. It is recommended
however not to change K1 and K2. It is better to do corrections with USOFS and the correction-factor
(see above).
