Unpacking and Parts Identification

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

1. Carrying case

2. Instrument

3. USB cable

4. CD-ROM with downloading software

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 9535/9535-A

The TSI Model 9535/9535-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 9535/9535-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

Use the Computer Interface USB Cable provided with the Model
9535/9535-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

C a u t i o n

This symbol is used to indicate that the data port of the Model
9535/9535-A is not intended for connection to a public
telecommunications network. Connect the USB data port only to
another USB port.

ON/OFF Key

Press to turn the Model 9535/9535-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”.

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.

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 adjust 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

Measurements

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

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™ Downloading Software

The TSI Model 9535/9535-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 CD­ROM.

To download data from the Model 9535/9535-A, connect the supplied
computer interface USB cable to the Model 9535/9535-A and to a
computer USB port. Then run the LogDat2 software. Within the
LogDat2 software, either select the tests to be downloaded or double­click on a test to open it.

Maintenance

The Model 9535/9535-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 9535/9535-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

The Model 9535/9535-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 9535/9535-A. If the enclosure of the Model 9535/9535-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.
