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 pulling
gently on the probe cable with the other hand.
