CO
2
Gas flow reading
is unstable, oscillating
or does not reach set
value.
CO
2
Gas supply line is
not connected correctly.
Inspect CO
2
gas line to ensure gas supply line
is connected securely and correctly.
Insufficient
CO
2
gas
pressure.
Set CO
2
gas pressure to 1 bar (14.5 psi).
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.
The N
2
gas line valve is
open but not in use and
not connected to N
2
gas
supply (unit with O
2
control only).
If the O
2
channel is not in use, close the N
2
gas
supply line (dead end tubing) and set the O
2
channel to ”OFF” on the device display or In-
cuControl.
The O
2
concentration is
set too high.
Make sure the ratio of O
2
/CO
2
concentration is
set correctly.
The CO
2
level over-
shoots the set point
considerably.
Defective valve or flow
sensor.
Contact
CO
2
regulation is very
slow.
CO
2
level
has
not
reached the set value.

Let CO
2
level adjust for 15 minutes.
CO
2
The channel has
been turned “ON” just
after it was “OFF” for a
while.
It will take up to 10 minutes for the CO
2
level
to reach the adjusted set point.

Open the dead-end tubing for the N
2
gas sup-
ply.
N
2
Gas supply line is
not opened.

2
gas line.
N
2
Gas supply line is

Inspect N
2
gas line to ensure gas supply line is
connected securely and correctly.

Please note that it can take up to 5 minutes until the set CO
2
concentration is reached
3
The gas mixer must not be switched off for a CO
2
concentration of ambient air (appr. 0,04%). Please set the CO
2
value
in the gas mixer at 0% to reach a CO
2
concentration of ambient air.
