chamber.  This dual wavelength method of measuring CO

2

 allows the instrument 

to compensate for ancillary effects like sensor aging and contamination. 

12.3. OPERATION WITHIN THE T803 ANALYZER 

Operationally, both the CO

2

 and O

2

 sensors are transparently integrated into the 

core analyzer operation.  All functions can be viewed or accessed through the 
front panel. 

 The 

CO

2

 concentration is displayed in the upper right-hand corner, alternating 

with O

2

 concentration.   

  Test functions for the slope and offset of CO

2

 and of O

2

 are viewable from the 

front panel along with the analyzer’s other test functions. 

  Calibration of each 

 

sensor is performed via the front panel CAL.  See 

Section 9 for more details. 

Stability of each

 

sensor can be viewed via the front panel (see Section 9).   

12.3.1.1. ELECTRONIC OPERATION OF THE CO

The CO

2

 PCA is powered by 12 VDC from the analyzer via the relay card, which 

outputs a 0-5 VDC analog signal to the analyzer’s CPU via the motherboard that 
corresponds to the concentration of CO

2

 measured by the probe.
