Operation

The O

Reference SETUP Screen is displayed by repeatedly pressing the

key from the Combustion Test Screen. Use this screen to select the

reference level that the analyzer will use to calculate the CO and NX

gas levels as referenced to Oxygen.

NOTE:

The O

reference level for ‘standard’ PCA models 20,

25, 30 and 35 is preset to 0% O

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

keys until

the desired level is displayed, and then press the

ENTER

key.
