Setting-up
Supplying Power to the Model TA465 Series
The Model TA465 AIRFLOWInstruments Air Velocity Metercan 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.

4 Chapter 2
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.

Connecting Ventilation or IAQ Probes
e
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.
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.
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.
6 Chapter 2
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.

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.
10 Chapter 2
Connecting the Optional Bluetooth®Portable Printer Device
To connect the Bluetooth printer to the Model TA465, power on the
unit and the printer. Then press the MENU soft key. From the Menu
use the and keys to highlight Bluetooth Functions and press the
key. Highlight Discover Devices and press the key. If other TSI
Bluetooth-printers are in the area, turn them off before searching. The
Model TA465 will then search for and list all available Bluetooth
devices.
For more information on establishing Bluetooth connections, refer to
TSI Applications Note AF-150.
Connecting to a Computer
Use the Computer Interface USB Cable provided with the
Model TA465 to connect the instrument to a computer for
downloading stored.
USB Communications Port
C a u t i o n
This symbol is used to indicate that the data port of the
Model TA465 is not intended for connection to a public
telecommunications network. Connect the USB data port
only to another USB port on a safety certified computing
device.
Protection provided by the instrument could be impaired
if used in a manner other than specified in this user
manual.

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 r
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

DISPLAY SETUP
Display Setup menu is where you will setup the desired parameters to
be displayed on the instrument screen. With a parameter highlighted
you can then use the ON soft key to have it show up on the instrument
screen or select the OFF soft key to turn off the parameter. Use
PRIMARY soft key to have a parameter show up on the instrument
screen in a larger display. A total of 5 parameters can be shown on
the display, 1 primary (large font) and 4 secondary. Parameters
shown in the Display Setup screen are dependent on the type of
probe currently connected.
When set to PRIMARY, measurement will be the large font on the
display.
When set to ON, measurement will be displayed as a secondary
parameter (up to 4 can be displayed).
When set to OFF, measurement will not be displayed.
