Calibration
Since all sensors of the Cicero EM are calibrated fully
automatically, the use of this menu is not required in
normal operation. The following functions can be
calibrated in this menu:
– O
2
sensor with 21% O
2
by volume.
– Flow sensor.
– O
2
sensor with 100% O
2
by volume.
– Linearity check of the O
2
sensor.
– Zero point of the gas sensor.
The significance of the symbols is as before:
?
= Enquires whether an action has been performed
or a setting made.
u
= Waiting period. The selected test step is being
carried out by the system.
✔
= The action has been completed successfully.
O
2
-sensor 21% by volume
New sensors must be allowed to run in for 15 minutes.
(The zero point stability is increased)
For the inspiratory O
2
-sensor:
●
Remove the sensor cell and expose to ambient air.
●
Select the
»O
2
sensor«
field and confirm.
The sidestream O
2
-sensor is calibrated automatically.
For manual calibration:
●
Select the
»O
2
sensor 21 Vol.%«
field and confirm.
Wait until the clock symbol (
u
,
U
, … ) is replaced by a
tick (
✔
).
●
Reconnect the inspiratory sensor (if used).
Flow sensor
This procedure is only required if the flow sensor is not
calibrated automatically. Auto-calibration is only possible
if gas measurement is connected.
Manual calibration deactivates auto-calibration until the
equipment is restarted or for a maximum of 24 hours.
●
Ensure that there is no movement of air inside the
sensor and that pure air is present in the sensor (seal
one side with your hand and hold horizontally to
prevent false calibration. See also page 177).
●
Select the »
flow-sensor
« field with the rotary control
and press to confirm. The tick (
✔
) indicates that
calibration is complete.
