Chapter -2 Setting-up

Supplying Power to the Alnor® AVM410/AirflowTM Instruments TA410

The Alnor® AVM410/AirflowTM Instruments 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/ AirflowTM Instruments 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 and temperature 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 pulling gently on the probe cable with the other hand.
