The function of each of the default Data Channels is described below:

CONC:

Samples NO

, NO and NO

concentration data at one minute intervals and

stores an average every hour with a time and date stamp. Readings during
calibration and calibration hold off are not included in the data. The last 800
hourly averages are stored.

PNUMTC:

Collects sample flow and sample pressure data at five minute intervals and
stores an average once a day with a time and date stamp. This data is useful for
monitoring the condition of the pump and critical flow orifice(sample flow)
and the sample filter(clogging indicated by a drop in sample pressure) over
time to predict when maintenance will be required. The last 360 daily averages
(about 1 year) are stored.

CALDAT:

Logs new slope and offset every time a zero or span calibration is performed,
also records the sample concentration reading just prior to performing a
calibration.

NOTE:
This Data Channel collects data based on an event (a calibration) rather than a
timer. This Data Channel will store data from the last 200 calibrations. This
does not represent any specific length of time since it is dependent on how
often calibrations are performed. As with all Data Channels, a time and date
stamp is recorded for every data point logged.
