Unpacking and Parts Identification

Carefully unpack the instrument and accessories from the shipping
container. Check the individual parts against the list of components below. If
anything is missing or damaged, notify TSI immediately.

1. Carrying case

2. Instrument

3. USB cable

4. CD-ROM with downloading software

Chapter 1

N o t e

For temperature measurements, make sure that at least 3 inches
(7.5 cm) of the probe is in the flow to allow the temperature sensor to
be in the air stream.

Chapter 2

Setting-up

Supplying Power to the Model 9545/9545-A

The TSI Model 9545/9545-A VELOCICALC 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.

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 pulling gently
on the probe cable with the other hand.

Connecting to a Computer

C a u t i o n

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.

Use the Computer Interface USB Cable provided with the Model
9545/9545-A to connect the instrument to a computer for downloading
stored data.

For more information on how to download stored data see Chapter 3 section
titled LogDat2™ Downloading Software.

4 Chapter 2

ON/OFF Key

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.

Arrow () Keys

Press to scroll through choices while setting a
parameter.

 (Enter) Key

Press to accept a value or condition.

Arrow ( or ) and
Menu Soft Keys

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.

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”.

Operation

Keypad Functions

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.

5

Menus

N o t e

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.

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  or  soft keys to scroll through the settings for each option and
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  or  soft keys to scroll through the types and
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.

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

Log Settings

Auto-save

Log Interval

Cont-key

Log Interval

Measurements

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

Log Mode/Log Settings

You can set Log Mode to Manual, Auto-save or Cont-key.
 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.

 In Cont-key mode, the user starts taking readings and logging by

pressing the  key. The instrument will continue taking
measurements until the  key is pressed again.

 Auto-save and Cont-Key modes have the following additional Log

Settings:

 Pressing the  keys simultaneously will lock the keypad to

prevent unauthorized adjustments to the instruments. To unlock the
keypad, press the  keys simultaneously.

LogDat2™ Downloading Software

The Model 9545/9545-A comes with special software called LogDat2
Downloading Software, which is designed to provide you with maximum
flexibility and power. To install this software on your computer, follow the
instructions on the label of the LogDat2 CD-ROM.

To download data from the Model 9545/9545-A, connect the supplied
computer interface USB cable to the Model 9545/9545-A and to a computer
USB port. Then run the LogDat2 software. Within the LogDat2 software,
either select the tests to be downloaded or double-click on a test to open it.

Chapter 4

Maintenance

The Model 9545/9545-A requires very little maintenance to keep it
performing well.

Recalibration

To maintain a high degree of accuracy in your measurements, we
recommend that you return your Model 9545/9545-A 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 9545/9545-A 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
9545/9545-A. If the enclosure of the Model 9545/9545-A 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.
