Setting-up
Supplying Power to the Alnor AVM410/AIRFLOW TA410
The Alnor AVM410/AIRFLOW TA410 is powered with four size AA
batteries.
Installing the Batteries
Insert four AA batteries as indicated by the diagram located on the
inside of the battery compartment. The Alnor AVM410/AIRFLOW
TA410 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 Telescoping Probe
The telescoping probe contains the velocity, temperature, and humidity
sensors. When using the probe, make sure the sensor window is fully
exposed and the orientation dimple is facing upstream.
NOTE: For temperature measurements, make sure that at least 3 inches
(7.5 cm) of the probe is in the flow to allow the temperature sensor to be in
the air stream.
Extending the Probe
To extend the probe, hold the handle in one hand while pulling on the
probe tip with the other hand. Do not hold the cable while extending the
probe as this prevents the probe from extending.
Retracting the Probe
To retract the probe, hold the handle in one hand while gently pushing
on the probe tip with the other hand. If you feel the probe antenna
binding, pull gently on the probe cable until the smallest antenna section
is retracted. Collapse the rest of the antenna by pressing the probe tip.

Maintenance
The Alnor AVM410/AIRFLOW TA410 requires very little maintenance to
keep it performing well.
Recalibration

recommend that you return your Alnor AVM410/AIRFLOW TA410 to TSI
for annual recalibration. Please contact one of TSI’s offices or your local
distributor to make service arrangements and to receive a Return Material
Authorization (RMA) number. To fill out an online RMA form, visit TSI’s

AIRFLOW TA410 becomes broken, it must be replaced immediately to
prevent access to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month to
prevent damage due to battery leakage.
