The Range Setting screen defines the concentration range of the analog
outputs. For example, an SO
2
range of 0–50 ppb restricts the analog output
to concentrations between 0 and 50 ppb.
The screen shows the current SO
2
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. For more information about the dual and auto range modes, see
“ Range Mode Selection ” on page 3-66 . Pressing Range Setting, High
Range Setting or Low Range Setting, brings up a numeric keypad whereby
the user can select a range.
