2
control)
•
After turning in the chamber, the ambient oxygen concentration of approx. 20.9 vol.-% is displayed
after a delay of 10 minutes. During the first 10 minutes, O
2
control is not defined. Then O
2
is regulated
to the displayed setpoint value of 21 vol.-%.
•
For high O
2
setpoint values (with alternative control range option), equilibration time is max. 1.5 hours.
Humidity (without active humidification)
•
With humidity control effected via the Permadry

6.6 Operating the DuoDoor™ door lock
The DuoDoor™ door lock offers two different ways to open the doors, dependent on the glass door lock
position.
Opening outer door and glass door independently
When closing the glass door, close the glass door lock.
Then you can close and open the outer door using its handle.
The glass door will remain closed until you manually open the
glass door lock.
Figure 18: Closed position
Opening outer door and glass together
When closing the glass door leave the glass door lock in open
position. Then close the outer door. The glass door is pressed
against the gasket so that both doors are securely closed.
When opening the outer door, a magnetic device also opens the
glass door.
