CHAPTER 7 THE MODE-MENU
modified via SET and the arrow-keys. The change is terminated via
MODE.
Display of battery voltage. The value in
brackets shows the voltage observed
during the last saturation pulse (transiently decreased value due to
high current of halogen lamp). YIELD-measurements may become
erroneous, if the voltage during a pulse drops below 8.0 V (Error
message 6: CHECK BATTERY). The battery voltage is a non-linear
function of the remaining battery capacity. When dropped below
11.2 V (without saturation pulse) the remaining capacity is approx.
20 % and recharging soon will become necessary. In this case there is
a warning (BAT-sign blinking in the left corner of the upper display
line).
34: BATT: 12.8V (12.3)
F: 448 745Y 6.2E 20L
Display of internal temperature of the
instrument which is measured close to the
optical unit. An increase of temperature causes a decrease of
measuring light intensity and, hence, simulates a decrease of
fluorescence yield. This may effect measurements of qP, qN and
NPQ, but not
of YIELD and ETR.
35: INT.TEMP: 24C
F: 448 745Y 6.2E 20L
Command to reset all instrument settings
(which can be varied via the MODE-
menu) to the standard settings preset at the factory (see in section
7.1).
36: RES.SETTINGS: (SET)
F: 448 745Y 6.2E 20L
Number and date of origin of current
program version of the MINI-PAM which
is resident on EPROM.
37: PROGR.M2.24(170299)
F: 448 745Y 6.2E 20L
Function to move the present MEMORY-
front to any number between 1 and 4000.
This function may be important when the MEMORY is full and the
user wants to avoid overwriting of certain older data.
38: MEMORY: 125 (SET)
F: 448 745Y 6.2E 20L
