Instantaneous value and concentration value:

The concentration display of Ch (component) where sampling components such as “CO2”, “CO” or “O2 are displayed in the component display, indicates current concentration values of the measured components contained in gas that is now under measurement.

O2 correction concentration values:

Ch components where “cv**” is displayed as “cv CO” in the component display are calculated values. They are obtained from the following equation by setting sampling components, O2 instantaneous/ concentration values and O2 correction reference value (see item 6.8).

Correction output = ⎛ 21- On ⎞ ⋅ Cs ⎝⎜ 21− Os ⎠⎟
