1. Select the waveform area to access the waveform setup menu.
2. Select [
Waveform
] and select [
CO2

8.3.3 Measurement Limitations
Measurement accuracy may degrade due to:
„ Leakage or internal leakage of the sample gas.
„ Mechanical shock
„ Cyclic pressure which is greater than 10 kPa (100 cmH2O)
„ Other interference source (if available)
8.3.4 Troubleshooting
When the sampling system of the CO2 module works incorrectly, check if the sampling tube
is kinked. If not, remove the sampling tube from the watertrap. Then, if a prompt message
indicating airway malfunction appears on the screen, it means that the watertrap is occluded.
In this case, you must replace the watertrap. If no such prompt message is displayed, it means
that the sampling tube is occluded. Then you must replace the sampling tube.
