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.
NOTE: 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.
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 gently 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
9535/9535-A to connect the instrument to a computer for downloading
stored data. Connect the end labeled “COMPUTER” to the computer USB
port and the other end to the data port of the Model 9535/9535-A.
For more information on how to download stored data see Chapter 3 section
titled LogDat2™ Downloading Software.
Caution: 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.

Operation
Keypad Functions
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.
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”.

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  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 5 types: Round Duct, Rectangle Duct, Duct
Area, Horn and Pressure Units. 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.
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.

Chapter 3
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 CD-ROM.
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 double-click on a test to open it.

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.
