Interpretation of Parameters
CO
2
(in)
The amount of CO
2
(in ppm) at the inlet of the analyzer
CO
2
(out)
The amount of CO
2
(in ppm) at the outlet of the leaf chamber
CO
2
(dif)
The difference between the CO
2
in and CO
2
out values.
H
2
O (in)
The amount of H
2
O (in kPa) at the inlet of the analyzer
H
2
O (out)
The amount of H
2
O (in kPa) at the outlet of the leaf chamber
H
2
O (dif)
The difference between the H
2
O in and H
2
O out values.
PAR
Photosynthesis Active Radiation in terms of цmol/m
2
/s
FLOW
The set flow rate of the analyzer (in lpm)
W
Mass flow rate in terms of mol/m
2
/s
T (air)
Temperature of the ambient air (in °C) in the leaf chamber. This requires the temperature
sensor to be installed for meaningful results.
ATM
Atmospheric pressure (in kPa)
Pn
Net photosynthesis rate in terms of цmol/m
2
/s
InTCO
2
Internal CO
2
цmol/mol
T (leaf)
Temperature of the leaf as measured by infrared temperature sensor (in °C)
C
Leaf Stomatal conductance mmol/m
2
/s
Internal T
Temperature of the analyzer environment (in °C)
E
Transpiration Rate mmol/m
2
/s
“EXIT to quit”
Aborts current operating function to the default menu
“ENTER file menu”
Allows the user to enter the file menu system:
“SHIFT 2 (D) = del”
Command to delete an existing file; press +
“EXIT file menu”
Returns to the default menu
“Y = delete ALL”
Command to delete all existing files; press + . This must be confirmed
before the instrument will erase all the files.
“Date”
Current running date
“Time”
Current running time
“START/ENTER to go”
Reminds the user that pressing will start the measurement process.
“ENTER to select”
Notifies the user to press to perform the listed functions:
“Change clock”
Allows the user to change the time and date settings
“Calibrate CO
2
”
Allows the user to calibrate the zero and span for CO
2
measurements.
“Calibrate H
2
O”
Allows the user to calibrate the zero and span for H
2
O measurements using external
sources
“Calibrate Temp”
Allows the user to set the TSCAL1 and TSCAL2 parameters of the temperature sensor.
“Calibrate Flow”
Allows the user to calibrate the flow meter to external standards.
“Calibrate ATM Pr”
Precisely adjusts atmospheric pressure (in kPa)
