Setting-up

Supplying Power to the Alnor CF910/AIRFLOW IAQ910

The Alnor CF910/A

Installing the Batteries

Insert four AA batteries as indicated by the diagram located on the
inside of the battery compartment. The Alnor CF910/AIRFLOW IAQ910
is designed to operate with either alkaline or NiMH rechargeable
batteries, although it will not recharge NiMH batteries. Battery life will
be shorter if NiMH batteries are used. Carbon-zinc batteries are not
recommended because of the danger of battery acid leakage.

Using the Integral Probe

The sensing probe relies on the diffusion of air. For best results, try to
keep the sensing probe surrounded by moving air. Do not breathe on the
probe. Humans exhale CO
take time for the probe to re-stabilize.

IRFLOW IAQ910 is powered with four size AA batteries.

Press to begin the field-calibration process. To re­calibrate in the field, first connect zero gas to the
instrument and open the regulator. Then use the

ST and ENTER keys to select ZERO. The

instrument will automatically make zero itself after
one minute.

After zeroing the sensor, connect span gas to the
instrument and open the regulator. Then use the

ST and ENTER keys to select SPAN. The

instrument will take one minute to make a reading.
Then use the
concentration displayed on the instrument to
match the concentration on the gas cylinder.
