Setting-up

Supplying Power to the Model 9515 VELOCICALC Air Velocity Meter

The Model 9515 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 Model 9515 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 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.

cloth and isopropyl alcohol or a mild detergent. Never immerse the
Model 9515. If the enclosure of the Model 9515 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.
