LI-600 Porometer/Fluorometer Instruction Manual
7-2
Caution: Do not apply pressure to the aperture
clamp to achieve a seal on the leaf. This can warp the
aperture clamp, interfere with the instrument’s
optics, and produce measurement errors.
Instrument will not automatically log a
measurement
If the instrument will not automatically log a meas-
urement, check that Auto Mode is enabled for the given
configuration (see Automode Setup on page5-2).
Ensure that the instrument is properly sealing on a leaf.
Ensure that stability criteria are adequate for your meas-
urement. See Stability criteria on page9-9.
The display layout is blank
A blank layout will appear on the display if no variables
are selected in the configuration. A measurement can
still be taken if the display layout is blank. The user
selects variables for the display layout in configuration
management in the software (see Display Layout on
page5-9).
A blank layout will appear on the display if a con-
figuration was removed from the instrument before exit-
ing a corresponding menu. Upload the configuration
using the computer software then select it on the instru-
ment.
A completely blank display (without time, battery per-
centage, or other indicators) indicates a problem with
the display itself.
