15.4 Setting RR Source
To set RR source:
1. Enter the [CO2 Setup] menu.
2. Select [RR Source] and then select a source or [Auto] from the dropdown list.
The [RR Source] settings of Resp and CO
2
module are linked. For details, please refer to the section Setting RR Source of
chapter Resp.
15.5 Setting Barometric Pressure Compensation
Both sidestream and microstream CO
2
modules have the function of automatic barometric pressure compensation (the
system automatically measures the barometric pressure which the monitor is exposed to). You must modify the
barometric pressure based on the actual situation as follows:
1. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password→[Maintain
CO2 >>]→[Calibrate CO2 >>].
2. Select [Barometric Pressure] and then enter the value of barometric pressure to which the monitor is exposed to.
15.6 Measurement Limitations
The following factors may influence the accuracy of measurement:
 Leaks or internal venting of sampled gas
 Mechanical shock
 Cyclic pressure up to 10 kPa (100 cmH
2
O)
 Other sources of interference, if any
15.7 Leakage Test
When the sidestream CO
2
module needs maintenance, the monitor prompts on the CO
2
waveform area: [Need
maintenance. Enter CO
2
setup menu.] Then, you can access [User Maintenance >>]→ [Maintain CO
2
>>], and
perform leakage test according to the prompt messages on the menu.
