Where:
On: The value of the O
2
correction reference value (Value set by
application)
Os: Oxygen concentration (%)
Cs: Concentration of relevant measured component. Note that Os
does not exceed the O
2
limit value set in “Other Parameter”
See Section 3.6 Maintenance Mode.
The corrected sampling components are NO
X
, SO
2
and CO only.
O
2
correction concentration average value:
In the Ch (component) and O
2
average value where “CV/AV **” is
displayed as “ AV CO” in the component display, a value obtained by
averaging O
2
correction concentration value or O
2
average value in a
fixed time is output every 30 seconds.
Averaging time can be changed between 1 minute and 59 minutes
or 1 hour and 4 hours according to the average time settings (See
Section 3.5.7 Parameter Setting).
The set time is displayed as “1h” , for instance, in the range display.
* The measurement ranges of O
2
correction concentration value and O
2
correction concentration average value are the same as that of the
measuring components. Also, the measurement range of O
2
average
value is the same as that of O
2
.
