NOx/NO Factor
NOx/NO: all the nitrogen oxides which are present in the flue emissions (Nitrogen oxide = NO, Nitrogen dioxide
= NO
2
); total nitrogen oxides = NOx (NO + NO
2
).
In the combustion processes, it is found out that the NO
2
percentage contained in the fumes is not far from very
low values (3%); hence it is possible to obtain the NOx value by a simple calculation without using a direct
measurement with a further NO
2
sensor.
The NO
2
percentage value contained in the fumes can be however set at a value other than 3% (default value).
Autozero/Pump:
This submenu is used to set the duration of the analyser auto-calibration cycle. It may also be used to switch off
or switch on the sample pump temporarily. The sample pump cannot be switched off if the auto-calibration cycle
is under way.
Operator:
The name of the operator conducting the analysis may be set or modified through this submenu. A maximum of
three names may be stored. The name of the selected operator will be printed on the analysis report.
Report header setup:
This allows the Company or Owner’s name to be entered in four lines with 24 characters each, together with
other details (e.g. address, tel. no.). This data will be printed on the heading of the analysis report.
