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 and temperature 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 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 LogDat2TM 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.

Chapter 3 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 ( ) 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.

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
The display setup menu is where you will set up the desired parameters to be displayed on the running screen. With a parameter highlighted you can then use the ON soft key to having it show up on the running screen or select the OFF soft key to turn off the parameter. Use the 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

The 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 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 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.

D ATA LOGGING

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.

LogDat2TM Downloading Software

The TSI® Model 9535/9535-A comes with special software called LogDat2TM 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 LogDat2TM 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 LogDat2TM software. Within the LogDat2TM software, either select the tests to be downloaded or double-click on a test to open it.

Chapter 4 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® Incorporated for annual recalibration.

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.
