Setting-Up
Supplying Power to the Q-T
The Q-T
RAK IAQ Monitor must be powered in one of two ways: four size
AA batteries or the supplied AC Adapter.
Installing the Batteries
Insert four size AA batteries as indicated by the diagram located on the
inside of the battery compartment. TSI ships the Q-T
batteries. NiCd rechargeable batteries may also be used.
Using the AC Adapter
The AC Adapter allows you to power the Q-T
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
NiCd batteries.
The Q-T
RAK 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.
Instrument Setup
The Q-T
RAK comes with special software called TRAKPRO, which is
designed to provide you with maximum flexibility and power when using
the Q-T
RAK. The following sections describe how to install the software and
setup the computer.
Setting-up T
RAKPRO software contains a very comprehensive Help Function. This
T
RAKPRO Data Analysis Software
utility provides all the necessary information to guide you in all aspects
of software operation.
Connecting the Q-T
Each Q-T
RAK comes equipped with an RS-232 cable and a 25-pin to
9-pin serial cable adapter. One end of the cable is a 25-pin D
subminiature connector labeled COMPUTER; the other end is an RJ-45
modular connector that mates with the logging instrument. Serial port
connectors always have pins (male) on the computer side.

1. Locate an available serial port on your computer: COM1, COM2,
COM3, or COM4.
2. If the port has a 25-pin connector, you do not need the adapter. If
the port has a 9-pin connector, plug the 25-pin end of the adapter
into the RS-232 cable.
Connect the RS-232 cable to the available serial port on your

Set-Up the Communications Port
To communicate with the Q-T
the proper COM port. T
specific COM port, or it can automatically find a Q-T
RAK, the software must be configured for
RAKPRO can be manually set to operate on a
RAK that is
attached to any COM port. To set up the COM port, do the following:
1. Turn on the Q-T

Select the baud rate for the port. Higher baud rates
are recommended to transfer data at a faster rate.
Select a lower baud rate only if you are having
trouble communicating at a higher rate.
4. Select Test to verify that you have set up the communications port
properly. The system displays an informative message indicating
whether it was able to establish communications.

RAK.
6. Select
OK to accept the setup or Cancel to discard the changes.
Note: Some computers do not communicate reliably at baud rates
above 9600.
Setting the Real-Time Clock
The Q-T
RAK has an internal real-time clock that keeps track of the time
of day (the format is HH:MM where HH is the hour in 24-hour format
and the MM is minutes) and the date. It is very important for the
RAK to have the time and date correctly set; otherwise, date and time
Q-T
stamping of recorded data and calibrations will not be correct.
There are two ways to set the time and date. The first is to use the
supplied T
RAKPRO Data Analysis Software.
Programming the Date/Time Using TrakPro

1. Make sure the Q-T

to the Q-T
RAK using the “arrows” keys. Alternately, the date and
time may be manually entered into the dialog box.
4. Select Send to reprogram the Q-T
RAK.

Manually Setting the Real-Time Clock
To set the time and date with the keypad, you must press and hold the
SAMPLE key down while the Q-T

RAK displays the time of day during
RAK “beeps.” You will
have an opportunity to view and/or change the hours, minutes, year,
month and day of month in sequence. Use the up and down arrow keys
(!") to change a setting. Use the SAMPLE key to store each setting
and advance to the next one.
Using the Probe Stand
For your convenience, the Q-T
RAK is supplied with a probe stand so
that the probe can be located above a table surface while unattended. To
use it, simply detach the probe from the Q-T
RAK mounting clips and
slide it onto the stand.
Connecting the Optional Model 8925 Portable Printer
To connect the Model 8925 printer to the Q-T
RAK, locate the Printer
Interface cable (supplied with optional printer) and connect the 9-pin
end labeled “PRINTER” to the printer and the other end to the data port
on the Q-T
RAK. Always turn the Q-TRAK on BEFORE the 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 Model 8925 Portable Printer Operation and Service Manual.

Operation
Overview
The Model 8550 and Model 8551 Q-T
temperature, and relative humidity. In addition the Model 8551 also
measures CO concentration. All parameters are measured simultaneously in
a single probe. The Q-T
RAK has four modes of operation, Survey, LOG 1,
LOG 2, and LOG 3. When the Q-T
mode which is used to display real-time readings and to determine statistics
such as average, minimum, and maximum readings. LOG 1 mode is used to
record individual data points for later analysis using a factory set protocol.
LOG 2 and LOG 3 modes have user-defined protocols, set up using
RAKPRO software. TRAKPRO software is used for analysis of data taken in
T
any of the three LOG modes, but cannot be used on samples taken in Survey
mode.
