If unsatisfactory results are observed, please refer to Section 7 - troubleshooting.
5.7
NO
2
to NO Converter Efficiency
The efficiency of the NO
2
to NO converter can impact readings and may degrade over time. The
converter efficiency must be measured to ensure the efficiency is 96% or greater and to compensate
for converter inefficiencies impacting results.
In the S44 there are two NO
2
to NO converter coils and both of these needs to be tested on a regular
basis (refer to Section 1.5.8).
Standard Error of Y about X must be less than 1% of FS value for both NOx and Nx channels.
