Setting modulation light source intensity.
It is adjustable between 0.1
:
mol and
1
:
mol when using an open body clip, a PAR Clip, or a dark clip. The settings range
from 5% to 100% in 5% increments. The correct setting depends upon the distance from
the sample and the nature of the sample. The optimum setting for RLC is not as critical as
it is for Fv/Fm and quenching measurements if momentary dark adaptation is used as in
Ralph (2005), but it is important if true dark adaptation is required, as in Rascher (2000).
It must, however, be high enough to make a measurement and prevent the “Fluorescence
signal too low” error.
Put a leaf, of the type to be measured in a study, into the PAR Clip or open body clip, or
dark clip, and place the fiber optic probe all the way into the PAR Clip or Open body
Clip, or dark clip.
The modulated light is always on when a measuring screen is viewed.
