Gas line restriction.
Make sure that the gas lines are not blocked
or kinked. Please note: The system must be
restarted after the interruption is removed.

Please make sure the set values are set to ambient air values (0% CO
2
, 21% O

) in case the correspond-
ing gas is not connected. Additionally, keep in mind that the maximum O
2
concentration depends
on the set CO

concentration. See chapter
for further details.

Humidity Channel Readings
Error Description
Possible Cause
Possible Solution
Humidity
channel
reading is “0”.
Humidity sensor not con-
nected.
Connect the Incubation Chamber as shown
in Figure
Condensation on the humid-
ity sensor.
Open and turn around the Heated Lid (Fig-
ure
), remove water with a lint free tissue
and allow the sensor to dry. If set humidity
is close to 100%, reduce set value by about
5–10%.
Defect humidity sensor.
Blow exhaled air directly on the sensor. You
should see an increase of humidity. If the
humidity sensor is not giving readings, it is
likely defective. Contact
The humidity does
not reach set value.
Incubation Chamber open or
not closed properly.
Make sure the Incubation Chamber is closed
properly.
