main menu. Control keys are different between windows. For in-
stance, the uppermost button in the sidebar triggers saturation
pulse analyses in case of the first three top level windows (cf.
Table 6, page 50) but the same button starts automated experi-
ments in windows A Yield, Induction Curve, Light Curve
and Recovery Curve.
Sections 7.2.1 to 7.2.10 will introduce all 10 top level windows in
detail.
7.2.1 Basic Data
The Basic Data window (Fig. 27, page 53) displays a reduced set
of four data for fast sampling under field conditions. From these
data, the Ft and PAR represent current measurements but the
Y(II), or F

M
, and the ETR are derived from the last saturation
pulse analysis.
The bottom edge of the Basic Data window provides keys for
frequently used commands: the command Rec starts a new da-
ta set (Record), Fo,Fm determines maximum PS II photochem-
ical yield, Clock starts repetitive triggering of saturation pulses
or an automated experimental routine, and Mark opens the
window “New Marker” in which the letter saved with each satura-
tion pulse analysis (“mark”) can be defined.
To change the marker letter, use up and down keys in the win-
dow “Change Marker”. The currently selected letter is shown on
the top edge of the window. Touching the SET key confirms
the current selection and returns to the Basic Data window.
