Line of variables "NOx correction factor":
In this line you can set up the NO
x
to NO flow correction factor.
Options: 0.1 to 10
Menu line "Calculate factor using pressure ration...":
Via this line you can change to a submenu, where you can start the calculation of an
NO/NO
x
correction factor. This method will calculate the correction factor using the
capillary pressure ratio between NO and NO
x
:
1) Give NO and NO
x
to the analyzer with the same pressure and flow as you would do for
a sample detection.
2) Press the F3 key (CALC): The NO/NO
x
correction factor will be calculated by the
signals automatically.
Menu line "Calculate factor using span gas response ratio...":
Via this line you can change to a submenu, where you can start the calculation of an
NO/NO
x
correction factor. This method will calculate the correction factor using the span
gas pressure ratio between NO and NO
x
:
1) Give span gas to the analyzer with the same pressure and flow as you would do for a
sample detection.
2) Press the F3 key (CALC): The NO/NO
x
correction factor will be calculated by the
signals automatically.
