Setting Up
Supplying Power to the Q-TRAKTM Plus IAQ Monitor
The Model 8552/8554 Q-TRAKTM Plus IAQ Monitor may be powered with
four AA alkaline batteries or the optional AC adapter.
Installing the Batteries
Insert four AA-size batteries, as indicated by the diagram located on the
inside of the battery compartment. TSI ships the Q-TRAK Plus monitor
with alkaline batteries. Rechargeable batteries may also be used (battery
charger and batteries are not included and are not available from TSI).
Using the AC Adapter
The AC adapter allows you to power the Q-TRAK Plus monitor from an
AC wall outlet. When using the AC adapter, the batteries (if installed)
will be bypassed. The AC adapter is not a battery charger and will not
charge rechargeable batteries.
The Q-TRAK Plus monitor has an internal, non-user accessible battery
that is used to keep memory intact when power is turned off. Changing
the AA-size batteries or disconnecting the AC adapter will not cause
data to be lost. This battery is designed to last for years. TSI will install
a new battery, if necessary, when the unit is returned to the factory for
service.
!
Caution
The use of an improper AC adapter will cause severe damage
to the instrument.
Instrument Software and Communications Setup
The Q-TRAK Plus IAQ Monitor comes with special software called
TRAKPROTM Data Analysis Software, which is designed to provide you with
maximum flexibility and power when using the Q-TRAK Plus monitor. The
following sections describe how to install the software and set up the
computer.
5
Setting up TRAKPROTM Data Analysis Software
Follow the instructions on the label of the TRAKPRO software to install
the software on your computer. TRAKPRO software contains a very
comprehensive Help Function. This utility provides all the necessary
information to guide you in all aspects of software operation. The
software is shipped on a CD-ROM. It is available on diskette format,
upon special request. Updates are available from the TSI website.
Connecting the Q-TRAK Plus IAQ Monitor to the Computer
Each Q-TRAK Plus monitor comes equipped with an RS-232, 9-pin
serial cable. One end of the cable is a 9-pin D subminiature connector
labeled COMPUTER; the other end is an RJ-45 modular connector that
connects with the Q-TRAK Plus communications port. Serial port
connectors always have pins (male) on the computer side.
1.
Locate an available RS-232 serial port on your computer: for
example, COM1 or COM2.
2.
Connect the RS-232 cable to the available serial port on your
computer.
3.
Connect the RJ-45 connector to the Q-TRAK Plus monitor
communications port.
Setting up the Communications Port
To communicate with the Q-TRAK Plus monitor, the software must be
configured for the proper COM port. The TRAKPRO software can be
manually set to operate on a specific COM port, or it can automatically
find a Q-TRAK Plus monitor that is attached to any COM port. To set up
the COM port, do the following:
6
1.
Turn on the Q-TRAK Plus monitor.
2.
Start the TRAKPRO software.

correctly and that it is communicating with the Q-TRAK Plus
monitor. The system displays an information message indicating
whether it was able to establish communications.
5.
As an alternative, select Find Port, to have the monitor search the
available COM ports, looking for an attached Q-TRAK Plus
monitor.
6.
Select OK to accept the setup, or Cancel to discard the changes.
Using the Optional Instrument Stand
The Q-TRAK Plus IAQ Monitor can be used with an instrument stand
(available as an accessory). When placed on a level surface, the instrument
stand is designed to hold the instrument and the probe at a convenient
viewing angle. The instrument stand may also be used to hang the monitor
on a wall.
To use the stand, simply detach the battery door from the monitor and
replace it with the instrument stand (see Figure 2-2).

Chapter 3
Operation
Overview
The Model 8552/8554 Q-TRAKTM Plus IAQ Monitor measures CO2,
temperature, relative humidity, calculates dew point, wet bulb, and %
outside air, and measures one (1) additional parameter. The Model 8554 will
also measure CO. The instruments have three main modes of operation:
Survey, Sample, and Data Log.
Survey mode: When the Q-TRAK Plus monitor is first turned on, it will
be in the Survey mode. This mode is used to display the real-time
readings of the sensors. The instrument will update the displayed
readings once each second.
Sample mode: The Sample mode is used to capture a 10-second,
averaged reading of all the parameters. These “single sample points”
may be stored in memory and can be displayed later, or downloaded to a
computer using the TRAKPRO software.
Data Log mode: The Data Log mode is used to record readings over a
period of time, and store these readings in the instrument memory. Data
files may be downloaded to a computer for later analysis using the
TRAKPRO software. Q-TRAK Plus has three different data log modes.
Q-TRAK Plus IAQ Monitor Keypad
The Model 8552/8554 Q-TRAK Plus IAQ Monitor is controlled through a
series of menus that are navigated using the arrow keys (S,T,W, X) (see
Figure 3-1). The Enter key () is used to select the desired option, while the
Escape key ( ) is used to go back to the previous menu. Each screen
contains prompting words and symbols. When pressing the keys on the front
panel, the monitor beeps to confirm each key press. The key allows access
to the Main Menu from the Survey mode.
Turning the Instrument On
Use the ON/OFF key to turn the Q-TRAK Plus monitor on and off. The
instrument's power-up sequence consists of a startup screen that displays the
instrument’s model number, serial number, firmware version, available
memory, date and current time. The display will also show various status
messages. The startup sequence lasts for 20 seconds before entering Survey
mode. A reminder may appear when the instrument is due for servicing.

Survey Mode
After the instrument has completed its power-up sequence, the Q-TRAK Plus
monitor will automatically go into the Survey mode.
Note:
It is not unusual for gas sensors to take some time to become
stable. If readings appear unusual at start-up, please allow
about one-half minute for the sensors to stabilize.
In the Survey mode, the Q-TRAK Plus monitor displays all parameters
simultaneously. The values are updated once per second. You may select
any of the parameters to be shown in large font at the top of the display. This
is called the primary parameter. Select the primary parameter by using the S
or T keys to highlight the parameter of interest, then press the key to
display that parameter in large font at the top of the screen. In addition, the
units of some parameters may also be changed. For example, temperature
may be shown in either °F or °C. To adjust the units, scroll to the desired
parameter using the S or T keys, then adjust the units using the W or Xkey
(refer to the units section in this chapter, see Figure 3-2).

Memory Considerations
The Q-TRAKTM Plus IAQ Monitor has a great deal of memory and
will not normally run out. The instrument contains separate
memory for the single points and for the logged tests (filling up the
memory for one type of data will have no affect on the other type).
The Q-TRAK Plus monitor can store approximately 440 separate
single points; in addition to 48,671 logged data points separated by
as many as 110 tests. That is, the instrument can also store
approximately 811 hours (33 days) of logged tests, when recording
at 1 minute logging intervals (the number of hours of logged tests
may be more or less, depending upon the logging interval).
The total test time should be considered when selecting a logging
interval. Shorter logging intervals use memory more quickly than
longer intervals. The logging interval and the available memory
determine the maximum possible duration of a data logging session.
Maximum logging duration = %memory available x 48,671 x logging interval
To prevent loss of any logged data, it is recommended you
download your data to the computer using the TRAKPRO software
as often as possible.
Auxiliary Sensor
For each of the logging modes the auxiliary sensor parameter is
logged along with the standard parameters as long as the auxiliary
probe is connected to the instrument prior to the start of logging.
If….
the auxiliary sensor is connected
before the start of logging…
Then….
…the Q-TRAK Plus monitor will
record the sensor data during
logging.
the auxiliary sensor is connected
after the start of logging…
…the Q-TRAK Plus monitor will
NOT record the sensor data during
logging.
the auxiliary sensor is disconnected
during logging…
…the Q-TRAK Plus monitor will
display "Invalid Data" for the
sensor for any time while the
sensor is disconnected.

Chapter 3
Keypad Lockout Switch
Recording data over extended time periods in Log Mode 1, 2, or 3
often requires leaving the Q-TRAK Plus monitor unattended. To
reduce the risk of having an unauthorized person either
intentionally or inadvertently interrupt the measurements, you can
lock the keypad. When lockout is engaged, no values can be seen
on the display.
The keypad lockout switch is located on the side of the Q-TRAK
Plus monitor between the probe mounting brackets. It is a small
slide switch and is recessed so that a pointed instrument must be
used to move it.
The instrument case is labeled next to the switch with the symbols
"|" and "0." With the switch in the "|" or on (up) position, all keypad
functions will work normally. There are two ways to use the
lockout switch.
If….
…the lockout is engaged prior to the
start of logging (switch is in the "0"
position)…
Then….
…the Q-TRAK Plus monitor will
operate normally until logging
begins.
…the lockout is engaged after the
start of logging.
…the keypad will ignore any key
presses until the switch is placed in
the | position.

Calibration and Maintenance
The Model 8552/8554 Q-TRAKTM Plus IAQ Monitor requires very little
maintenance to keep it performing well.
The Q-TRAK Plus monitor may be calibrated in the field using the
instructions below. Even so, we recommend that you return your Q-TRAK
Plus monitor to TSI for calibration annually. For a nominal fee, we will
quickly clean and recalibrate the unit, update software and firmware, and
return it to you in “as new” working condition along with a Certificate of
Calibration and NIST Traceability. The factory calibration is more precise
than can be accomplished with the procedures below. This “annual checkup”
helps ensure that the Q-TRAK Plus monitor is always in good operating
condition.
Calibrating the CO2 Sensor
TSI recommends calibrating the Q-TRAK Plus monitor CO2 measurement
monthly to help ensure accurate readings.
To calibrate the CO2 sensor, please follow the procedure below. You can
also follow the prompts displayed on the screen while in user calibration
mode. You will need a cylinder of zero CO2 air or nitrogen for the zero
calibration and a cylinder of gas with a known concentration of CO2 for the
span calibration. Contact your local TSI distributor for available CO2
calibration kits (see Figure 4-4).
Note:
If using air for zero calibration, it must be specified to have
less than 10 ppm CO2. Ambient room air cannot be used (see
Appendix A).
The calibration procedure can be aborted at any time by pressing the key.
Any step in the calibration procedure can be repeated by pressing the S key.
1.
To put the Q-TRAK Plus monitor into CO2 calibration mode, press the
S or T keys to select CALIBRATION in the Setup Menu.

Calibrating the Temperature or Relative Humidity Measurement
To perform a temperature or humidity calibration on the Q-TRAK Plus
monitor you will need a reference temperature or humidity device, one that
is more accurate than the Q-TRAK Plus monitor. To obtain the best accuracy,
care must be taken so that both the Q-TRAK Plus probe and the reference
device are able to sense the same air. Also, it’s best to calibrate at a
temperature and humidity that is near the range you typically measure.
Note:
!
User calibration of humidity sensor can only be done in units
of %RH.
Caution
Never submerge the probe or Q-TRAK Plus monitor in water or
any other liquid. The sensor will be damaged.
1.
Locate the Q-TRAK Plus probe and the reference device sensor so that
they sense the same air conditions.
2.

Using the Telescoping Probe
To extend the probe, grasp the handle in one hand while gently pulling
on the probe tip with your other hand. Be aware that the AVP cable
slides through the telescoping probe as it is extended or retracted.
To retract the probe, grasp the handle and push the probe tip toward the
handle. The rest of the probe sections can then be collapsed using a
finger or the palm of your hand. Be sure not to block or hold the cable at
the handle since the cable should freely pass through the handle while
the probe is collapsed.
The thermistor bead velocity sensor is located in the sensor window of
the telescoping probe. When using the probe, be sure that the last
section of the probe is fully extended exposing the entire sensor
window.
Measuring Air Velocity
When the AVP is connected to the Q-TRAK Plus, velocity
measurements will automatically be displayed along with the standard
Q-TRAK Plus parameters. The velocity measurement units are userselectable between feet per minute (fpm) and meters per second (m/s),
and between actual and standard units as illustrated in Table 5-1. To
select the velocity measurement units, highlight the velocity reading
Auxiliary Sensors

with the S or T (up/down arrow) key and then change the units
displayed using the W or X (left/right arrow) key.
Table 5-1: Velocity Measurement Units

Measurements are made by holding the probe so the sensor window is
positioned in the desired measurement location with the sensor window
perpendicular to the air flow stream. Be sure the sensor window is fully
exposed and the orientation indicator arrow on the probe tip is pointing
downstream. Hold the probe as still as possible while the measurement
is taken.
!
Caution
When positioning the probe for a measurement, be certain the
orientation indicator arrow on the probe tip is pointing
downstream in the direction of the air flow.
Measuring Air Flow Rate or Average Velocity
Volumetric flow rate can be estimated based on an average velocity
measurement across a known area such as a duct. You can input the
cross-sectional dimensions for round, square, or rectangular ducts and
flow rate will be displayed in cfm, m3/h or L/s accordingly. The
measurement units can be changed by simply highlighting the flow
displayed with the S or T key and then changing the units displayed
using the W or X key.

Maintenance
Periodically inspect the AVP sensor window to ensure that it is clean.
Dust and oil deposits on the sensor will affect measurement accuracy.
The telescoping probe should also be kept clean. Dirt or oil
accumulation will affect the ability to extend and retract the probe. Use
a soft cloth dampened with water to remove accumulation of unwanted
material. Dry the probe with a gentle stream of air or allow to air dry. If
oil or grease is present, a small amount of high-grade isopropyl alcohol
may be applied to clean the AVP.
!
Caution
Be sure the probe is disconnected from the Q-TRAK Plus before
cleaning so the AVP is not powered. Do not use strong
solvents or high-pressure air to clean the probe or sensor—
permanent damage could result.
Calibration
For the highest degree of accuracy, TSI recommends that instruments be
returned to the factory annually for calibration. For a nominal fee, the
probe will be checked and recalibrated to original factory specifications
and returned to you with a new National Institute of Standards and
Technology (NIST) calibration certificate. To have your AVP
recalibrated, please follow TSI’s Returned Material Authorization
(RMA) procedure on our web site at http://rma.tsi.com.
Special Display Messages
In extreme cases, temperature or velocity conditions may exceed the
operating specifications of the AVP potentially inhibiting the AVP from
providing an accurate measurement. If the temperature at the sensor
exceeds the maximum operating limit, the Q-TRAK Plus display will
read TEMP HI. If temperature is below the minimum operating range,
the instrument display will read TEMP LO. If the air velocity exceeds
the upper range of the specification, the Q-TRAK Plus display will read
VEL HI. Under such conditions, the measurement accuracy may be
compromised and the AVP might be damaged.
Storage
It is recommended that the Air Velocity Probe accessory be stored
unattached from the Q-TRAK Plus IAQ Monitor when not in use.

Appendix B
Standard Velocity vs. Actual Velocity
Measurements
Thermal air velocity sensors are sensitive to changes in both air density and
air velocity. Thermal anemometers, therefore, typically indicate velocities
with reference to a set of standard conditions. For TSI instruments, standard
conditions are defined as 70°F (21.1°C) and 14.7 psia (101.4 kPa). Other
manufacturers may use a different set of standard conditions.
Standard velocity is the velocity the air would be moving if temperature and
pressure were at these standard conditions. It is usually the most useful
measure of air flow because it defines the heat carrying capacity of the air.
Actual velocity is the velocity at which a microscopic particle of dust would
be traveling if it were in the air stream with zero acceleration.
In some instances, actual air velocity may be of interest rather than standard
air velocity. To obtain the actual velocity, multiply the standard velocity by
the density correction factor:
Actual Velocity = (Standard Velocity)
(460 + T)(14.7)
(460 + 70)(P)
where T is ambient temperature in ºF and P is the ambient pressure in psia.
The conversion in metric units is:
Actual Velocity = (Standard Velocity)
(273 + Tm )(101.4)
(273 + 21.1)(Pm )
where Tm is the ambient temperature in ºC and Pm is the ambient pressure in
kPa.
