The Auto/Manual Mode screen allows selection of the automatic mode
(NO/NO ), NO mode (manual NO), NO
x
prereactor mode (manual prereact). The auto cycle mode switches the
mode solenoid valve automatically on a 10 second cycle so that NO, NO
and NO concentrations are determined. The manual NO mode puts the
x
mode solenoid valve into the open position so that the sample gas bypasses
the NO -to-NO converter. Therefore, only the NO concentration is
2
determined. The manual NOx mode puts the mode solenoid valve into the
closed position so that the sample gas passes through the NO
converter. Therefore, only the NO
manual modes, additional averaging times of 1, 2, and 5 seconds are
available from the Averaging Times screen.
