Supplying Power to the Model 9545/9545-A
The TSI Model 9545/9545-A
V
ELOCI

ALC
Air Velocity Meter
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 9545/9545-A 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 Optional AC Adapter
When using the AC adapter, the batteries (if installed) will be bypassed.
Be sure to provide the correct voltage and frequency, which is marked
on the back of the AC adapter. The AC adapter will not recharge the
batteries.
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 and humidity measurements, make sure that at
least 3 inches (7.5 cm) of the probe is in the flow to allow the temperature
and humidity sensors 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 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.
