If the CI-
301CS is used, enter number “1”. If the CI
-
301AD is used, enter number “2”. If the CI
-301LA is
used, enter number “4”. If both the CI
-301CS and the CI-
301AD are used, enter number “3”. If both the
CI-301CS and the CI-
301LA are used, enter number “5”. If the CI
-301AD and the CI-301LA are used,
enter number “6”. If all the three accessories are used, enter number “7”. To operate the CI
-340 without
any accessories, enter number “0”, or just press
key. If one or more accessories are to be used,
you will be asked to enter one or all of following parameters:
Desired Temperature? (Deg C)
___
Desired CO
2
Concentration? (ppm)
___
Desired Relative Humidity? (%)
___
Desired PAR? (mmol/m
2
/s)
___
For each question, enter a number and press
key. Refer to the appendices for detailed
information.
At this point, an area of the leaf sample will be asked for. Enter the area (in cm
2
). It has been designed
so that areas too large or small will severely affect necessary calculations for photosynthesis,
transmission or stomatal conductance rates. The allotted range is .001 ~ 10,000 cm
2
. If the leaf you are
using fully covers the leaf chamber window, enter the area of the window. Table 7-1 and 7-2 at the end
of this chapter list the window sizes of all the leaf chambers CID, Inc. manufactures.
Flow rate? (lpm)
___
Enter the intended flow rate (in lpm). The pump and flow sensor have been designed to operate under
controlled specifications. Use a flow rate between 0.1 and 1 lpm.
But if the CI-301AD is used, the flow
rate should be < 0.5 lpm.
Finally, the CI-340 will ask whether an open or closed system measurement will be conducted. The
default entry is for the open system (press
to use the default). Press “C” to select the closed
system measurement or “O” for open system. The closed system function will ask for t
he chamber
volume (in liters). Refer to Table 7-2 for closed system chamber information. Closed system
measurements can be terminated when a certain change in time ( T) or change in CO
2
( CO
2
) has been
measured, or the
key can be pressed. Press “T” for
T or press “C” for
CO
2.
The system will
then ask for the length of time or the change in CO
2
required for the measurement. Also, refer to the
CLOSED AND OPEN SYSTEMS section for further elaboration of measuring procedures.
