6.4. Verification
The verification kit contains two optical filters (labeled “low” and
“high”) with certified reference absorptions of approximately 0.09 A
and 0.18 A, which corresponds to approximately 250 ppb and 500
ppb of ozone. The exact values are specified in the enclosed calibra
-
tion certificate. The absorption of the filters were chosen to lie in the
center and at the upper limit of the measurement range of the AMI
Codes-II O3.
The verification procedure confirms the photometric accuracy and
linearity of the core components of AMI Codes-II O3, i.e. photometer
and converter electronics, over the entire measurement range by
comparison of the absorbances measured by the AMI Codes-II O3
with the certified reference values. A maximum deviation of ±0.010A
is required for a successful photometer verification.
