Make sure to press the key(s) firmly and hold until the “beep” sounds. When the
instrument is busy performing a task, it may not respond immediately to a pressed key.
•
Check to see that the key sequence(s) are valid. Randomness does not guarantee a proper
operational instrument.

O readings dramatically fluctuate or deteriorate during measurements . .
•
Check for proper tube, chamber connections. A good secure fit obtains and promotes
more accurate measurements and results.
•
Make sure the chamber head is closed properly. The measuring environment should be
appropriately sealed by the chamber head so that the intended sample is analyzed
accurately.
•
The sample(s) may not be a good source.
•
Ambient, internal operating temperatures may be too extreme. Check with the instrument
accessory specifications for ideal operating conditions.

•
Check for proper calibration(s). Using a Di-nitrogen (N2) source for both the CO
2
and
H
2
O concentration is highly recommended for the 0-ppm source. Using a 300- or 600-
ppm source is highly recommended for the known source of CO
2
; a known source
between 1 ~ 7.5 kPa of water vapor pressure is required.
•
The sample(s) may not be a good source.
If at the end of setting photosynthesis parameters, the “Exit to Quit” screen remains on longer
than 30 seconds, it is possible that the flow calibration is not calibrated properly.
