Setting-up

Supplying Power to the Model 9565 Series

The Model 9565 VelociCalc® Air Velocity Meter can be powered in
one of two ways: four size AA batteries or the AC adapter.

Installing the Batteries

Insert four AA batteries as indicated by the diagram located on
the inside of the battery compartment. The Model 9565 is
designed to operate with either alkaline or NiMH rechargeable
batteries. Battery life will be shorter if NiMH batteries are used. If
NiMH batteries are used the DIP switch will need to be changed.
Refer to the next section, DIP Switch Settings. Carbon-zinc
batteries are not recommended because of the danger of battery
acid leakage.

DIP Switch Settings

To access the DIP switch, remove the batteries from the battery
compartment. On the inside of the battery compartment, there is
a window with a single DIP switch (see figure below). The table
below shows the functions for the switch.

N O T E

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.

“D” Shaped
mini-DIN connector

Connecting Ventilation or IAQ Probes

The ventilation and IAQ probes have a “D” shape overmolding on the
mini-DIN connector which must align with the connector at the base of
the 9565 series meter. This will ensure the probe is properly
connected and remains so during use. Once connected and turned
on, refer to the DISPLAY SETUP for displaying the desired
measurements.

Using the Telescoping Thermoanemometer Probes

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.

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.

N O T E

The pitot velocity needs a valid temperature to perform the
standard or actual velocity correction. This is accomplished
in the “Actual/Std Setup” menu. If no probe capable of
measuring temperature (plug in probe or thermocouple) is
connected, the“Temp Source” must be set to “Entered”. The
duct air temperature must then be manually inputted by the
user using the “Entered Temp” setting. If the “Temp Source”
is set to Probe or Thermocouple 1 or 2, and no probe is
connected, dashes (------) will appear on the display.

For more information on entering the temperature manually,
refer to the Actual/Standard Setup section of this manual.

Connecting an Optional Pitot Probe or Airflow (straight
pitot) Probe

When connected to a pitot probe, air velocity or air volume can be
measured. A pitot probe can be connected to the “+” and “-”
pressure ports on the Model 9565-P using two pieces of tubing of
equal length. The total pressure port of the pitot probe connects
to the “+” port on the meter, and the static pressure port of the
pitot probe connects to the “-” port on the meter.

Maintenance

The Model 9565 and probe accessories require very little
maintenance to keep it performing well.

The Model 9565 and accessory probes can also be recalibrated in the
field using the CALIBRATION menu. These field adjustments are
intended to make minor changes in calibration to match a user's
calibration standards. The field adjustment is NOT intended as a
complete calibration capability. For complete, multiple-point
calibration and certification, the instrument must be returned to the
factory.

Cases

If the instrument case or storage case needs cleaning, wipe it off with
a soft cloth and isopropyl alcohol or a mild detergent. Never immerse
the Model 9565. If the enclosure of the Model 9565 or the AC adapter
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.
