*: means an extra error should be added in case of gas interference when CO2 measurements are
performed under 0-40mmHg.
Alarm limit Range Step
EtCO2 High (low limit + 2) to 99 mmHg
EtCO2 Low 0 to (high limit - 2)mmHg
FiCO2 High 0 to 99 mmHg

* Accuracy applies for the following conditions:
1. Measurements begin after the CO
2
module warms up;
2. Ambient pressure is from 750 to 760 mmHg, and ambient temperature from 22 to
28ºC;
3. The measured gas is a dry gas and the balance gas N
2
;
4. Gas sample flow rate is 100 ml/min, respiration rate is 50 rpm with a fluctuation
between ±3 rpm, and I:E is 1:2.
When the operating temperature (near the module detector) is 5-25°C or 50-55°C, or the
respiration rate is greater than 50 rpm, the measurement accuracy is: ±4 mmHg (0 to 40
mmHg) or 12% of the reading (41 to 99 mmHg).
