Performing zero calibration during
ventilation
The zero calibration is performed with a clean
CO2 sensor that has been removed from the
cuvette!
1 Connect the CO
2 sensor and wait at least
3 minutes for the CO
2 sensor to complete its
warm-up phase.
2 Remove the CO
2 sensor (A) from the
cuvette (B).
3 Press the Settings key.
4 On the screen, select and activate the
CO
2 Zero calib. – Run line. The screen
displays the text Remove the sensor from
cuvette then press rotary knob.
5 Confirm. The zero calibration starts and the line
displays Busy. During the zero calibration, the
message ! CO
2meas. inaccurate/failed is
displayed.
Note the possible warm-up time. During zero
calibration, ventilation settings can be changed.
After a successful zero calibration, the message
Pass is briefly displayed.
6 Reattach the CO2 sensor (A) to the cuvette (B).
If zero calibration was not successful:
Oxylog 3000 plus displays the alarm message
!!! CO
2 Zero calib. failed.
Redo the zero calibration.
If zero calibration is still not possible:
1 Check whether the sensor (A) is soiled and
clean it if necessary. If the sensor is defective,
replace the sensor.
2 Redo the zero calibration.
WARNING
Risk of patient injury
The CO
2 measurement can be inaccurate and
lead to a risk of patient injury.
– Before the CO
2 filter check can be per-
formed, perform a CO2 zero calibration.
– Do not breathe on the CO
2 sensor during
the CO
2 zero calibration and the CO2 filter
check.
– Only perform the CO
2 zero calibration and
the CO2 filter check at ambient tempera-
tures between 10 and 40 °C (50 and
104 °F).
– Do not perform the CO2 zero calibration
when exposed to direct sunlight.
