If the above message is repeated, the BabyCO meter must be
returned to CareFusion Ltd, or an authorised agent, for sensor
replacement.
Sensor life greater than 2 years. The sensor life depends upon both
the amount of exposure to CO and other gases, particularly solvents
such as alcohol and cleaning fluids.
If the signal from the CO sensor is too high, a new calibration value
will not be stored and the following will be displayed when
calibration is attempted:
The most likely cause for this is using an incorrect concentration of
calibration gas. Ensure that the concentration of calibration gas is
correct (20ppm), that the connections to the gas cylinder are
secure, and then repeat the calibration procedure.
In order to stop any gas leak from the can after calibration, ensure
that the control knob is tightened firmly.
Important Notes:
•
Only certified calibration gas from a reputable source should be
used.
•
Ensure that no CO is present on the sensor for 3 minutes before
starting the calibration procedure.
•
Ensure that the instrument and gas cylinder have stabilised at
room temperature before calibrating.
