SO
Range
The SO
2
outputs. For example, a SO
to concentrations between 0 and 50 ppb.
The display shows the current SO
used to change the range. The range screen is similar for the single, dual,
and autorange modes. The only difference between the screens are the
words "High" or "Low" displayed to indicate which range is displayed. The
example that follows shows the SO
information about the dual and autorange modes, see "Single Range
Mode", "Dual Range Mode", and "Autorange Mode" earlier in this
chapter.
Table 3–5 lists the available standard ranges.
