The x-axis of the graph represents time
elapsed. As the measurement progresses the
graph will move to the right. The graph can
display approximately two minutes of
measurement at a time. The y-axis of the
graph displays the range of the concentration
in % for CO
2
and O
2
, and the dynamic range is
labeled at the top. The y-axis scale is set by
the highest value shown in the buffer.
The total measurement time is displayed below
the graph. The flowrate (mL/min) is displayed
at the bottom. If Relative Humidity (% RH) and
Temperature (degrees Celsius) are not seen
on the display, go to Setup > RH Conversion
and enter the actual temperature of the
measurement gas (see page on page 33).
