Setting-up
Supplying Power to the Model 9555 Series
The Model 9555 V
two ways: four size AA batteries or the AC adapter.
Installing the Batteries
Insert four AA batteries as indicated by the diagram located on the
inside of the battery compartment. The Model 9555 is designed to
operate with either alkaline or NiMH rechargeable batteries. Battery life
will be shorter if NiMH batteries are used. If NiMH batteries are used
the DIP switch will need to be changed. Refer to Appendix B,
Switch Settings. Carbon-zinc batteries are not recommended because of
the danger of battery acid leakage.
Using the 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.
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.
ELOCICALC Air Velocity Meter can be powered in one of
DIP
NOTE: For temperature and humidity measurements, make sure that at
least 3 inches (7.5 cm) of the probe is in the flow to allow the temperature
and humidity sensors 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 the Optional Bluetooth Portable Printer
To connect the Bluetooth printer to the Model 9555, power on the unit and
the printer. Then select the MENU soft key. From the Menu use the
S and T
keys to highlight Discover Printer and press the key. If other TSI Bluetoothprinters are in the area, turn them off before searching. The Model 9555 will
then search for and list all available Bluetooth devices. Select the device
”Handy700”.
If the Model 9555 has previously been connected to a TSI printer, then it
should automatically reconnect to that printer.
If the printer prints question marks (??????), asterisks (******), or random
characters, reset it by turning it off and then on again. If necessary, refer to
the Portable Printer Manual.
Connecting to a Computer
Use the Computer Interface USB Cable provided with the Model 9555 to
connect the instrument to a computer for downloading stored data or for
remote polling. Connect the end labeled “COMPUTER” to the computer
USB port and the other end to the data port of the Model 9555.
For more information on how to download stored data see Chapter 3 section
TrakPro™ Data Analysis Software.

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
Press to turn the Model 9555 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. Pressing the
will lock the keypad to prevent unauthorized
adjustments to the instruments. To unlock the
keypad, press the
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

Set up, Data Logging, Applications, Calibration
and Printer.

stored at the same time.
ST keys simultaneously
ST keys simultaneously.
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.
5
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”.
Logging Interval
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 4 secondary parameters
can be selected at one time.
PRESSURE ZERO
To zero the pressure reading, select the Pressure Zero menu. The instrument
will indicate if the pressure zero was successful.
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.

The logging interval is a frequency period that the
instrument will log readings. For example, if the
logging interval is set to 30 minutes, each sample
will be the average of the last 30 minutes.
FLOW SET UP
In Flow Setup mode, there are 5 types: Round Duct, Rectangle Duct, Duct
Area, Horn and K-Factor. Use the g
types and then press the key to accept the desired type. To change the
value, highlight the Enter Settings option and press the key.

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 Model 9555
measures the actual barometric pressure.
DATA LOGGING
Measurements
Measurements to be logged are independent of measurements on the
display, and must therefore be selected under DATA LOGGING Æ
Measurements.
Log Mode/Log Settings
You can set Log Mode to Manual, Auto-save, Cont-key, Cont-time,
Program 1 or Program 2.
• 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.
• In Cont-time mode, the user starts taking readings by pressing the
key. The instrument will continue taking samples until a set period
of time has passed.
• Auto-save, Cont-Key and Cont-time modes have the following
additional Log Settings:

This option displays the memory available. Delete All, under Delete
Data, will clear memory and reset the memory available.
APPLICATIONS
You can choose Draft Rate, Heat flow, Turbulence and % Outside Air in the
Applications menu. After choosing one of these applications, take
measurements or enter data for each line.
Printing Data Using the Portable Printer
To print logged data, first enter the DATALOGGING menu. Then, use the
CHOOSE TEST item to select the data to be printed. After the test is
selected, use the VIEW STATS and VIEW SAMPLES items to select
statistics or individual data points to view and print. After selecting VIEW
STATS or VIEW SAMPLES, press the PRINT key to print the data.

Maintenance
The Model 9555 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 9555 to TSI for annual recalibration.

The Model 9555 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 9555. If the enclosure of the Model 9555 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.
