Operation
For accurate results the BabyCO meter should be used at room
temperature. If the instrument has been stored in cool or hot
conditions then allow time to reach room temperature prior to use.
Install the PP3 battery by sliding open the battery cover, clipping the
battery in place and replacing the cover. Insert the mouthpiece
adapter into the BabyCO meter and then insert a disposable
mouthpiece into the adapter. Turn the unit on by pushing the slide
switch to the middle position (CO). The display will show the
software version number momentarily whilst correction for ambient
levels is executed. During this time the unit must not be exposed to
any source of CO. The buzzer will then sound and the display will
change to:

Upon hearing the buzzer instruct the subject to inspire fully and hold
their breath for as long as is comfortable. The breath-holding period
is recommended to allow time for equilibration of alveolar gas.
The subject should then seal their lips around the mouthpiece and
exhale slowly and fully.
After emptying the lungs completely the display will show the
expired CO concentration in the expired air in parts per million
(ppm):
