module
<4 s@70 mL/min
Measured by using neonatal watertrap and 2.5 m neonatal
sampling line.
<5.5 s@100 mL/min
<7 s@70 mL/min
Measured by using adult watertrap and 2.5 m adult sampling line.
Pump rate 70 mL/min and 100 mL/min optional
Pump rate accuracy ±15﹪ of the set value or ±15 mL/min, whichever is greater
Start time
30 s. The module enters the warming up status after the startup
1 minute later, it enters the Full accuracy status
Stability ±0.8 mmHg within 24 hours

*Additional error caused by gas interference when measured at 0 to 40 mmHg
*Typical accuracy measurement conditions are:
1. Measurement starts when the module warm-up state ends.
2. Ambient pressure: 750 to 760 mmHg; room temperature: 22 to 28ºC.
3. The gas under test is dry gas and the balance gas is N2.
4. Pump rate: 100 mL/min; breath rate: not greater than 50 rpm; fluctuation of breath rate:
less than ±3 rpm; I:E: 1:2.
Operating temperature (approximate to the module detector): 15 to 25°C or 50 to 55°C.
Measurement accuracy: ±4 mmHg (0 to 40 mmHg) or ±12% of the reading (41 to 99 mmHg)
when the breath rate is greater than 50 rpm.
