O2 correction is only carried out, if O2 corrections > 11%.
For O2 < 11% no correction is allowed.
It’s require to correct the value for the 11% O2 by following formula
For O2 < 11% no correction is allowed.
It’s require to correct the value for the 11% O2 by following formula
Es = {(21 - Os) / (21 - Om) } x EM
Es = Calculated emission concentration at the standard percentage oxygen concentration
Em = Measured emission concentration
Os = Standard oxygen concentration
Om = Measured oxygen concentration
