Setting-up

Supplying Power to the Model 9545/9545-A

The TSI Model 9545/9545-A
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.

VELOCICALC Air Velocity Meter is powered

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.

Connecting to a Computer

Use the Computer Interface USB Cable provided with the Model
9545/9545-A to connect the instrument to a computer for downloading
stored data or for remote polling. Connect the end labeled “COMPUTER” to
the computer USB port and the other end to the data port of the Model
9545/9545-A.

For more information on how to download stored data see Chapter 3 section

LogDat2™ Downloading Software.

Caution: This symbol is used to indicate that the data port
of the Model 9545/9545-A is not intended for connection
to a public telecommunications network. Connect the USB
data port only to another USB port.

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

Test ID

Press to turn the Model 9545/9545-A on and off.
During the power up sequence the display will show
the following: Model Number, Serial Number,
Software Revision and Last Date Calibrated.

Press to scroll through choices while setting a
parameter.

Press to accept a value or condition.

Press arrow keys to change choices while setting a

parameter. Press the Menu soft key to select the

Menu selections, which are Display Setup,
Settings, Flow Setup, Actual/Std Set up, Data
Logging and Calibration.

Consists of all of the measurement parameters
stored at the same time.

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

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

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”.

Menus

DISPLAY SETUP

Display setup menu is where you will setup the desired parameters to be
displayed on the running screen. With a parameter highlighted you can then

use the ON soft key to have it show up on the running screen or select the
OFF soft key to turn off the parameter. Use PRIMARY soft key to have a

parameter show up on the running screen in a larger display. Only one
parameter can be selected as a primary, and up to 2 secondary parameters
can be selected at one time.

SETTINGS

Settings menu is where you can set the general settings. These include
Language, Beeper, Select Units, Time Constant, Contrast, Set Time, Set
Date, Time Format, Date Format, Number Format, Backlight and Auto Off.
Use the g
use the  key to accept settings.

FLOW SET UP

In Flow Setup mode, there are 4 types: Round Duct, Rectangle Duct, Duct

Area, and Horn. Use the g
then press the  key to accept the desired type. To change the value,

highlight the Enter Settings option and press the  key. Use the instructions

below to change the value of the type that you selected.

or h soft keys to scroll through the settings for each option and

or h soft keys to scroll through the types and

NOTE: The horn numbers are the models of the horns. For example, 100

refers to a horn model number AM 100. Only horns with Model
numbers as follows can be used with this function: AM 100,
AM 300, AM 600 and AM 1200. If a horn model number is chosen,
the instrument will return to measuring mode and use a
preprogrammed curve to calculate flow rate from velocity.

ACTUAL/STANDARD SETUP

Choose Actual/Standard measurements and parameters in the Act/Std Setup
menu. Within this menu, the user can also select Standard Temperature,
Standard Pressure and a source for the actual temperature. The actual
barometric pressure must be entered to convert air velocity and volume
measurements to actual conditions.

DATA LOGGING

Measurements

Measurements to be logged are independent of measurements on the
display, and must therefore be selected under DATA LOGGING Æ
Measurements.

Log Mode/Log Settings

You can set Log Mode to Manual, Auto-save.

• Manual mode does not automatically save data, but instead prompts

the user to save a sample.

• In Auto-save mode, the user manually takes samples that are

automatically logged.

Delete Data

Use this to delete all data, delete test or delete sample.

% Memory

This option displays the memory available. Delete All, under Delete
Data, will clear memory and reset the memory available.

™

LogDat2
