Data Labels
Data Labels are user-specified labels that can be
applied to each measurement, for example genotype,
plot number, or replicate. A label can be formatted as a
number, list, or barcode. A configuration can have up to
three labels, and at least one label must be a barcode to
enable the barcode scanner on the instrument.
Automode Setup
Automode Setup enables or disables Auto Mode meas-
urements on the instrument (see Taking a measurement
in Auto Mode on page 3-3) and Taking a measurement in
Manual Mode on page 3-4). Auto Mode automatically
monitors stability criteria.
When Auto Mode is enabled, the LI-600 determines
when to log a data point. It computes stability criteria
and compares it to the settings. Once two consecutive
data points are below the set threshold, the meas-
urement is considered stable, and the LI-600 logs the
data point. This is based on monitoring changes over
time (in seconds) to both the computed stomatal con-
ductance (
gsw ) and/or the de-modulated fluorescence sig-
nal ( F ).
When Auto Mode is not enabled, the instrument is in
Manual Mode , and a measurement is logged by press-
ing the Enter button when the user's stability criteria
are met.
Remarks
Remarks are optional comments that can be added to
each measurement. You can create up to three remarks;
one of those remarks can be applied to each meas-
urement. Remarks are selected on the instrument when
