7.3.4 Sensors
Selection of “Sensors” in the Main Menu opens the window
“Sensor Settings” (Fig. 48). This window consists of five links
leading to submenus (distinguished by

) and the option to se-
lect for light measurements the MINI-PAM-II internal PAR sensor
or the external sensor of the 2035-B leaf clip (Use Ext. PAR/Use
Int. PAR). An overview on window Sensor Settings and its com-
plex structure of submenus gives Fig. 49 (page 86).
Selecting “Internal PAR” opens the window “Internal PAR Sensor
Settings” (Fig. 50, page 87). This window is dedicated to calibra-
tion of MINI-PAM-II internal PAR sensor. The window displays
the current “Calibration Factor” of the internal PAR sensor. If the
miniature Spectrometer should be used for calibration of the in-
ternal PAR sensor, the spectrometer calibration factor
(Spec. Cal. Factor) is important. This factor corrects for the effect
of inhomogeneous illumination by actinic light of the diffusing
disk of the miniature spectrometer. Typically, the
Spec. Cal. Factor is adjusted by comparing the Calibration Fac-
