5.4.3.2. DUAL RANGE MODE (DUAL)  
Selecting the DUAL range mode allows the A1 and A2 outputs to be configured with 
different reporting ranges.  The analyzer software calls these two ranges low and high.   
 The 
LOW range setting corresponds with the analog output labeled A1 on the rear 
panel of the instrument.   
 The 
HIGH range setting corresponds with the A2 output.   
While the software names these two ranges low and high, they do not have to be 
configured that way.  For example: The low range can be set for a span of 0-1000 ppm 
while the high range is set for 0-500 ppm.   
In  DUAL  range mode the RANGE test function displayed on the front panel will be 
replaced by two separate functions: 
  RANGE1: The range setting for the A1 output. 
  RANGE2: The range setting for the A2 output. 
To select the DUAL range mode press following buttonstroke sequence 
.  
 
When the instrument’s range mode is set to DUAL, the concentration field in the upper 
right hand corner of the display alternates between displaying the low range value and 
the high range value.  The concentration currently being displayed is identified as 
follows: C1LOW (or A1) and C2 = HIGH (or A2).

In DUAL range mode the LOW and HIGH ranges have separate slopes 
and offsets for computing CO concentrations. The two ranges must be 
independently calibrated.
