Setting-up
Supplying Power to the Model TA465 Series
The Model TA465 AIRFLOW™ Instruments 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 TA465 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.
Caution: Make certain that power is turned off before changing the
DIP switch settings.

Do not attempt to charge alkaline batteries.
Using the AC Adapter
The AC adapter can be used to power the instrument or to
charge the NiMH batteries when the DIP switch in the battery
compartment is set to NiMH. If the DIP switch is set to
Alkaline, and the AC power adapter is connected, then the
batteries will be bypassed and the meter will be powered by
the AC adapter. Be sure to provide the correct voltage and
frequency, which is marked on the back of the AC adapter.

Chapter 2
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 TA465 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.
“D” Shaped
mini-DIN connector
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.
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 robe from extending.
Retracting the Probe
To retract the probe, hold the handle in one hand while gently
pulling the probe cable until the smallest antenna section is
retracted.
Setting-up
5
Do not use the instrument or probes near hazardous
voltage sources since serious injury could result.
Using the Pressure Ports (TA465-P)
The TA465-P includes pressure ports that can be used to measure
static and differential pressures in ductwork. For more information,
see Application Note AF-107.
Negative (-) Pressure Port
Positive (+) Pressure Port
Connecting the Static Pressure Probe
The Static Pressure probe included with the TA465-P is
connected to the + port on the TA465-P using the included
tubing. The Static Pressure probe is used to measure the duct
static pressure and features a magnet which holds the probe to
the ductwork.
6
Chapter 2
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 TA465-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.
For information on how to perform a duct traverse, refer to
Application Note AF-106.
NOTE
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.

Thermocouple Ports
The TA465 series includes two thermocouple ports at the base of the
meter. Any K-Alloy thermocouple with mini-connector can be
attached. See Display Setup for setting the thermocouple
temperature readings to be displayed as TC1, TC2, or TC1-TC2.
Connecting the Thermocouples
The K-Alloy thermocouple with mini-connector has one terminal
wider than the other. The wider terminal will be inserted into the
bottom of the TC1 or TC2 connector port.
K-alloy Thermocouple
TC1
TC2
Thermocouples from an alternate TSI supplier must have
the metal sheath electrically isolated from the wires
inside. Failure to meet this requirement may result in
false readings, electrical shock, or fire hazard.
Do not use the instrument or probes near hazardous
voltage sources since serious injury could result.

Common Terms
In this manual there are several terms that are used in different
places. The following is a brief explanation of the meanings of those
terms.
Sample
Consists of all of the measurement parameters
stored at the same time.
Test ID
A group of samples. The statistics (average,
minimum, maximum, and count) are calculated for
each test ID. The maximum number of test IDs
is 100.
Time Constant
The time constant is an averaging period. It is used
to dampen the display. If you are experiencing
fluctuating flows, a longer time constant will slow
down those fluctuations. The display will update
every second, but the displayed reading will be the
average over the last time constant period. For
example, if the time constant is 10 seconds, the
display will update every second, but the displayed
reading will be the average from the last 10
seconds. This is also referred to as a “moving
average”.
Log Interval
The logging interval is the period over which the
instrument will average the logged sample. For
example, if the logging interval is set to 30 minutes,
each sample will be the average over the previous
30 minutes.
Test Length
This is the time over which the data will be logged
in the “Continuous-Time” mode of data logging.

To maintain a high degree of accuracy in your measurements, we
recommend that you return your Model TA465, 960 series
thermoanemometer probes, IAQ and VOC probes to TSI for annual
recalibration. Please contact one of TSI’s offices or your local
distributor to make service arrangements and to receive a Return
Material Authorization (RMA) number. To fill out an online RMA form,
visit TSI’s website at http://service.tsi.com.

The Model TA465 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 TA465. If the enclosure of the Model TA465 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.

Temperature compensated over an air temperature range of 40 to 150°F (5 to
65°C).
The accuracy statement of ±3.0% of reading or ±3 ft/min (±0.015 m/s), whichever is
greater, begins at 30 ft/min through 9999 ft/min (0.15 m/s through 50 m/s).
Pressure velocity measurements are not recommended below 1000 ft/min (5 m/s)
and are best suited to velocities over 2000 ft/min (10.00 m/s). Range can vary
depending on barometric pressure.
Accuracy is a function of converting pressure to velocity. Conversion accuracy
improves when actual pressure values increase.
Accuracy with instrument case at 77°F (25°C), add uncertainty of 0.05°F/°F
(0.03°C/°C) for change in instrument temperature.
Accuracy with probe at 77°F (25°C). Add uncertainty of 0.1% RH/°F (0.2% RH/°C)
for change in probe temperature. Includes 1% hysteresis.
Overpressure range = 190 in. H2O (7 psi , 360 mmHg, 48 kPa).
