7.14 CO
2
Monitoring Failures
Phenomenon
Possible Cause
Solution
No CO
2
waveform.
Bad connection of CO
2
module.
Power off, reconnect CO
2
module.
CO
2
module defective.
Replace CO
2
module.
The CO
2
waveform is
smooth.
CO
2
module stays in
Standby mode.
Change the working mode of CO
2
module to Measurement.
The CO
2
sampling tube is
jammed or not connected
well.
Unplug the sampling tube and clear
foreign matters, and then connect it
again. Or replace the sampling tube.
CO
2
waveform looks a
mess, and the numeric value
has obvious errors.
CO
2
module has not been
zeroed for a long time, thus
the measurement is
inaccurate.
Open CO
2
setup menu and zero CO
2.
CO
2
waveform is smooth
and the numeric value
displays - - -.
CO
2
module stays in
standby mode.
Change the working mode of CO
2
module to Measurement.
Tube jam displays on the
interface in CO
2
measurement.
CO
2
sampling tube has a
jam.
Unplug the sampling tube and clear
foreign matters, and then connect it
again. Or replace the sampling tube.
CO
2
waveform is normal,
but data measurement has
an error.
CO
2
module has not been
zeroed for a long time, thus
the measurement is
inaccurate.
Open CO
2
setup menu and zero CO
2.
The settings of
compensation gas and air
pressure are inaccurate.
Open CO
2
setup menu and set
compensation gas and air pressure
correctly.
7.15 IBP Monitoring Failures
Phenomenon
Possible Cause
Solution
The IBP waveform is
available, yet IBP
measurement value is
unavailable.
The IBP module has not
been zeroed or zero drift
occurs.
Zero the IBP module.
The IBP waveform appears
and disappears time after
time.
Bad connection of the IBP
cable and sensor
Check the connection of IBP cable
and sensor.
The IBP waveform is flat
and there is no apparent
An unsuitable selection of
the ruler
Check whether the IBP label is
consistent with the measured site of
