5.4.3.3. AUTO RANGE MODE (AUTO)  
In AUTO range mode, the analyzer automatically switches the reporting range between 
two user-defined ranges (low and high).   
  The unit will switch from low range to high range when the CO
2
 concentration 
exceeds 98% of the low range span.   
  The unit will return from high range back to low range once both the CO
2
 
concentration falls below 75% of the low range span. 
In AUTO Range Mode the instrument reports the same data in the same range on both 
the  A1 and A2 outputs and automatically switches both outputs between ranges as 
described above.  Also the RANGE test function displayed on the front panel will be 
replaced by two separate functions: 
  RANGE1: The LOW range setting for all analog outputs. 
  RANGE2: The HIGH range setting for all analog outputs. 
The high/low range status is also reported through the external, digital status bits (See 
Section 3.3.1.4).
