3.3.4.5 General correction
Each measurement could be corrected according to the concentration of H
2
O (Dil. Probe mode), to
the concentration of O
2
, to the concentration of CO
2
and to the sample gas pressure.
Calculations made for each correction:
Correction of H
2
O:
Measurement (corrected) = Measurement x 100 / (100 – Measurement (H
2
O))
Correction of O
2
:
Measurement (corrected) = Measurement x (21 – Ref.(O
2
)) / (21 – Measurement (O
2
))
Correction of CO
2
:
Measurement (corrected) = Measurement x Ref.(CO
2
) / Measurement (CO
2
)
Correction of pressure:
Measurement (corrected) = Measurement x Ref.(Pres) / Measurement (Pres)
