NO/NOX/NO2 MODE

→
Example above: NO
To change to the NO/NO
x
/NO
2
Mode, press from the Measure Mode menu. The
current measuring mode (cycle) is indicated above the analyzer range.
The cycle times of the sample read are set on the
NO/NO
x
/NO
2
Mode Times screen. All
NO and NOx readings are displayed as averaged values.
The cycle begins with the NO reading. When the NO reading is completed, the analyzer
switches to the NO
x
mode (through the converter). When the NO
x
cycle is completed, the
analyzer updates the averaged NO and NO
x
values on the screen and the analog outputs.
At that point, the difference between the averaged value of NO and NO
x
is calculated as
the NO
2
concentration.
The cycle continues to repeat.
For advanced calibration and operation in NO/NOx/NOx mode, see NOx Correction
Factors.
NOTE: The NO/NO
x
/NO
2
Mode activates the “sample and hold” feature which allows
the analyzer to automatically cycle between NO and NO
