Cuvette Flow
Alteration to an existing flow rate causes transient disruption of CO
2
control which in turn affects calculated assimilation rate and Ci so wait a
minute or so for the system to readjust before collecting data. If the
new Control value is ± 20% of the old value a brief message will appear
in the status bar: “cuvette flow 20% out from set value”. This is simply a
transient that will disappear as the new target flow is approached.
Leaf Area
Options are identical to those described in Settings (See Settings (F2)
on page 73.
Controls Graph Set (F5)
Press Controls (F3) > Graph Set (F5) to change your Graph View options. You will find this especially
useful after completing system stability checks when a leaf is in the chamber. Then, your focus will likely
be on calculated parameters more than measured parameters. Because the dynamic range of a leaf
sample’s physiology may be unknown to you, it could be difficult to set the correct Y-axis scale, for
example, to keep constant oversight of rapid changes and trends over time. Here, Graph Set will allow
you to make quick corrections to Y-axis scales. The options are identical to those described in Settings
(F2)> Graph Set (F5). Press Controls (F3) > Graph Set (F5) > Clear (F5) at any time to refresh plotted
data in the graphs.
Toggle View (F4)
Toggle View (F4) is a simple function key used to switch between Numeric and Graph View. For
example, use Toggle View if there is a variable that you would like to monitor, but it is not currently
displayed in Graph View. One of many possible configurations of Graph View can be seen below with the
CO
2
control steps of an A/Ci curve displayed in the upper graph.
