For a negative set-point entry, enter the numerical value first and only then the negative sign
(-).
When operating without humidity (humidity switch (4) OFF) set the humidity set-point in Man-
ual Mode to 0 % r.H. in order to avoid alarms (in case of the humidity deviating by more than
+/- 5% from the set-point).
8.2 Entering the set point values when operating without illumination
The KBF LQC has been adjusted for operation with illumination. Since the illumination creates a heat
input in the chamber, this must be considered when entering a setpoint without illumination. For this rea-
son, adapting the setting of the temperature set-point according to the following table is required.

Adapting the setting of the humidity set-point according to the following table is also required.

8.3 Performance after power failure in Manual Mode
In Manual Mode (HAND), all functions reinstate exactly to the same situation the chamber had before
power failure. The set-points are immediately resumed. The power failure will appear in the event list. No
error message indicating that a power failure has taken place is displayed.
