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.
NOTICE 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.
3

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 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 LogDat2TM 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.

Chapter 3 Operation

Keypad Functions
ON/OFF Key
Arrow () Keys (Enter) Key Arrow ( or ) and Menu Soft Keys

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.

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
Time Constant

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.
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 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.
NOTICE
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 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.

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.
