13. Humidity system
The humidity system is turned on with humidity switch (4) located in the right lateral control panel.
The climatic chamber KBF-LQC is equipped with a capacitive humidity sensor. This results in a control
accuracy of up to
±
3 % r.H. of the set point. The temperature-humidity diagrams (Figure 23) show the
possible working ranges for humidity.
The preset temperature and humidity values should be situated within the optimum range
(hatched range in Figure 23).Only within this area can the unit will not be exposed to excessive
moisture due to condensation.
In the short-term set points outside the optimum range can also be targeted. The control accu-
racies of
±
3 % r.H., however, cannot be guaranteed in this case.
