Setting-up
Supplying Power to the Model 7575 Q-TRAK™ IAQ Monitor
The Model 7575 Q-TRAK Indoor Air Quality (IAQ) Monitor can be powered
in one of 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 7575 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 the next section, DIP
Switch Settings. Carbon-zinc batteries are not recommended because of
the danger of battery acid leakage.
DIP Switch Settings
To access the DIP switch, remove the batteries from the battery
compartment. On the inside of the battery compartment, there is a
window with a single DIP switch (see figure below). The table below
shows the functions for the switch.
Caution: Make certain that power is turned off before changing the
DIP switch settings.

Do not attempt to charge alkaline batteries.
Using the AC Adapter
The AC adapter can be used to power the instrument or to charge
the NiMH batteries when the DIP switch in the battery
compartment is set to NiMH. If the DIP switch is set to Alkaline,
and the AC power adapter is connected, then the batteries will be
bypassed and the monitor will be powered by the AC adapter. Be
sure to provide the correct voltage and frequency, which is marked
on the back of the AC adapter.
AC Adapter input
Connecting IAQ or Ventilation Probes
The ventilation and IAQ probes have a “D” shape overmolding on the miniDIN connector which must align with the connector at the base of the 7575
monitor. This will ensure the probe is properly connected and remains so
during use. Once connected and turned on, refer to the DISPLAY SETUP for
displaying the desired measurements.

Chapter 2
Using Optional Telescoping Thermoanemometer Probes
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 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 robe from extending.
Retracting the Probe
To retract the probe, hold the handle in one hand while gently pulling
the probe cable until the smallest antenna section is retracted.
Do not use the instrument or probes near hazardous
voltage sources since serious injury could result.
Thermocouple Ports
The 7575 series includes two thermocouple ports at the base of the monitor.
Any K-Alloy thermocouple with mini-connector can be attached. See
Display Setup for setting the thermocouple temperature readings to be
displayed as TC1, TC2, or TC1-TC2.
Connecting the Thermocouples
The K-Alloy thermocouple with mini-connector has one terminal wider
than the other. The wider terminal will be inserted into the bottom of the
TC1 or TC2 connector port.

Thermocouples from an alternate TSI supplier must have
the metal sheath electrically isolated from the wires
inside. Failure to meet this requirement may result in
false readings, electrical shock, or fire hazard.
Do not use the instrument or probes near hazardous
voltage sources since serious injury could result.
Connecting the Optional Bluetooth® Portable Printer Device
To connect the Bluetooth printer to the Model 7575, power on the unit and
the printer. Then press the MENU soft key. From the Menu use the  and 
keys to highlight Discover Bluetooth and press the
key. If other TSI
Bluetooth-printers are in the area, turn them off before searching. The
Model 7575 will then search for and list all available Bluetooth devices.
For more information on establishing Bluetooth connections, refer to TSI
Applications Note TSI-150.
Connecting to a Computer
Use the Computer Interface USB Cable provided with the Model 7575 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 7575.

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”.
Log Interval
The logging interval is the period over which the
instrument will average the logged sample. For
example, if the logging interval is set to 30 minutes,
each sample will be the average over the previous
30 minutes.
Test Length
This is the time over which the data will be logged
in the “Continuous-Time” mode of data logging.

The Model 7575 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 7575. If the enclosure of the Model 7575 or the AC adapter becomes
broken, it must be replaced immediately to prevent access to hazardous
voltage.
