16.5 Influence factors
The following factors may affect the measurement accuracy:
n Leakage or internal leakage of sampling gas.
n Mechanical shock.
n Other interference sources of interference.
16.6 Alarm Information and Prompts
When the alarm switches are set to "ON" in relevant menus, the physiological alarms caused by the parameter
exceeding the alarm limit may possibly trigger the recorder to automatically output the alarm parameter value and
corresponding waveforms.
Tables below describe the possible physiological alarms, technical alarms and prompt messages occurring during CO
2
measurement.

SENSOR
FAULT
The sensor error.
HIGH
Check that the sensor is properly plugged
in. Reinsert or reset the sensor if necessary.
If error persists, return sensor to factory for
servicing.
CO
2
SENSOR
OVER TEMP
The sensor temperature is
greater than 40℃
HIGH
Make sure the sensor is not exposed to
extreme heat. If error persists, return sensor
to factory for servicing.
CO
2
CHECK
SAMPLING LINE
The atmospheric pressure
exceeds the specified range.
LOW
Check whether the sampling cannula is
occluded or twined.
CO
2
ZERO
ERROR
An error was found during
Zeroing
LOW
Check and clean the air adapter, if the error
is not corrected, please calibrate zero.
CO
2
OUT OF
RANGE
The value being calculated is
greater than the upper CO
2
limit.
LOW
Calibrate zero.
