Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
The function of each of the default Data Channels is described below:
CONC: Samples Carbon Monoxide concentration (Low Range) 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.
This Data Channel also records the instrument 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.
4.12 Software Configuration
The software configuration can be displayed by entering the button sequence SETUP-CFG-
NEXT. For example the M300M could display:
MODEL M300M CO Analyzer
Stating that the instrument is Carbon Monoxide analyzer using the SBC40 computer. This
feature is useful for showing any special features that are present in the currently installed
PROM.
