after one
minute of operation, shut off heating module immediately and repeat "Prepare for Start Up"
checklist. (
See “Air-free method of measuring CO”)
The Air-free method of measuring CO
Air-free
measurement of CO takes account of the amount of excess air by incorporating an
adjustment to the as-measured ppm value, thus simulating air-free (oxygen-free) conditions in
the combustion gases. To do this, a reading of oxygen (O2) or carbon dioxide (CO2)
percentage is taken from the combustion gases along with the as-measured CO reading. This
can be done with a meter having the capability of measuring CO
and
O2 or CO2 percentage,
or it can be done with two different meters, one measuring CO ppm and one measuring O2 or
CO2 percentage.
If air-free CO is determined with a single meter, an integral electronic chip calculates the
air-free level from as-measured CO ppm and O2 percentage.
