completes the internal self-check, it will
display the approximate percentage of

stabilize in still air before displayed readings
can be considered accurate. Moving the
instrument may decrease this stabilization time.

Carbon dioxide concentrations will be
displayed in parts per million (ppm). The
IAQ10 can be left in a room to monitor
general conditions, but it is important to
ensure that the sensing holes at the top of
the meter are not covered or in a
downward position.
Press the READ key once to start taking a
CO2 sample; press it again to end the
sample. The minimum sample time is five
