Operation
The O
2
Reference SETUP Screen is displayed by repeatedly pressing the
MENU
key from the Combustion Test Screen. Use this screen to select the
O
2
reference level that the analyzer will use to calculate the CO and NX
gas levels as referenced to Oxygen.
NOTE: The O
2
reference level for ‘standard’ PCA models 20,
25, 30 and 35 is preset to 0% O
2
and cannot be changed.
For PCAs with just a CO sensor, the Combustion Test Screen can show
both the measured level of CO, and its calculated level referenced to
Oxygen displayed as CF. For PCAs with both CO and NX sensors, the
Combustion Test Screen can only show either the measured levels of CO
and NX, or their calculated levels referenced to Oxygen displayed as CF
and NF, respectively. Refer to Section 4.17 for set up instructions.
To select the analyzer’s Oxygen reference level, press the
st
keys until
the desired level is displayed, and then press the
ENTER
key.
