The CO
2
Range screen defines the concentration range of the analog
outputs. For example, a CO
2
range of 0–500 ppm restricts the analog
output to concentrations between 0 and 500 ppm.
The display shows the current CO
2
range. The next line of the display is
used to change the range. The range screen is similar for the single, dual,
and auto range modes. The only difference between the screens are the
words “High” or “Low” displayed to indicate which range is displayed. The
following example shows the CO
2
range screen in single mode. For more
information about the dual and auto range modes, see “
Single Range
Mode
”, “
Dual Range Mode
”, and “
Auto Range Mode
” earlier in this
chapter.
Table 3–5
lists the available ranges.
