CHAPTER 7 THE MODE-MENU
time constants (defined for 63.2 % of a signal change): 1: 0.05 s,
2: 0.2 s, 3: 1 s.
Setting of electronic signal gain
(amplification factor) which can be varied
between 1 and 12. By increasing GAIN not only the signal but also
the noise increases in proportion. Any change in GAIN requires a
new determination of the unavoidable background signal via AUTO-
ZERO (menu point 2).
49: OUT-GAIN: 2 (SET)
F: 448 745Y 6.2E 20L
Setting of intensity of measuring light
which can be varied between 0 and 12.
Any change in MEAS-INT requires a new determination of the
unavoidable background signal via AUTO-ZERO (menu point 2).
50: MEAS-INT: 8 (SET)
F: 448 745Y 6.2E 20L
Letter from A to Z for identification of a
particular type of sample. This MARK is
entered into the MEMORY with every new data set measured in
connection with a saturation pulse. It can be helpful when a number
of different plants are assessed in the field.
51: MARK: A (SET)
F: 448 745Y 6.2E 20L
