Monitoring Problems
When troubleshooting EtCO
2
problems, it is recommended to replace the EtCO
2
sensor first. If the
problem still exists, try to replace internal tubing, and tubing of the EtCO
2
module.
If the EtCO
2
module does not start work when you connect a sampling line, try to repeat the standard
testing sequence, for example:
1 Return to the Main Menu
2 Reconnect the sampling line
3 Reenter the Service EtCO
2
screen
4 Reenter the Test screen

Monitoring Problems
Symptom Possible Causes Suggested Solution
Failure to display measurement EtCO
2
Module failure • Replace the sampling line
•Replace EtCO
2
module
Processor PCA failure Replace Processor PCA
Therapy PCA failure Replace Therapy PCA
Reading inaccurate Sampling line is blocked or
damaged
• Replace sampling line
•Replace EtCO
2
module
The EtCO
2
Module does not start
when the sampling line is connected to
the DFM100. There is no EtCO
2
waveform on the display
• Sampling line is damaged
•EtCO
2
module failure or
sensor failure
• Replace sampling line
• Run an OpCheck. If the EtCO
2
test fails,
replace the EtCO
2
Module. If the EtCO
2
test
passes, examine the sensor for dirt or foreign
objects and clean the sensor. If the problem still
exists, replace Processor PCA.
