17.2.2 Preparations for CO2 Measurement

Plug the water trap into its receptacle before the measurement.

Open the CO2 SETUP menu and set WORK MODE to MEASURE. The “CO2 START

UP” prompt information is displayed on the screen until the startup is finished.

After the module start-up, the “CO2 WARM UP” prompt information is displayed on

the screen. At this time, the module is in the Warming–up status.

After the module warm-up, the module enters the Ready-to-measure status.

When the monitor is powered on for the first time, the CO2 module enters the STANDBY

mode by default. To activate the CO2 module, you must change the work mode to

MEASURE. The work mode of the CO2 module keeps unchanged when the monitor is

restarted. For instance, if the monitor is power off when the CO2 module is working in the

MEASURE mode, the CO2 module will automatically enter the MEASURE mode after the

monitor is restarted. For details about WORK MODE, please refer to the section Other Setup

in 17.2.3CO2 .

The measure CO2 concentration can be compensated in two ways:

•

ATPD (Ambient Temperature and Pressure, Dry Gas);

•

BTPS (Body temperature and pressure, Saturated);

ATPD means the CO2 value is measured in ambient temperature and pressure and dry gas,

while BTPS means the CO2 is measured at a temperature of 37., a relative humidity of 95%

and a 47mmHg (pH2O) partial pressure of moisture.
