Notes about Operation
Wireless CO2 Recorder
RTR-576 User's Manual
Do not connect an RTR-576 to your computer before first installing the supplied software that comes with the Base Unit you are using.
This product cannot measure CO or O2. Do not use it for purposes such as avoiding
O2 deficiency, CO intoxication or any other health related purpose.
Thank you for purchasing our product. To ensure safe and proper operation, please
read this manual thoroughly before use.
RTR-576 Package Contents
Setting up the RTR-576
This product has been designed for use in normal living conditions, and is not suited
for controlled environments such as a CO2 incubator. When measuring outdoors,
avoid exposure to sunlight, dust, rain, or wind. Also make sure to use in the
operating environment indicated in the specifications.

User's Manual (Warranty Included)
Do not expose the Unit to a strong impact. This will adversely affect measurement
accuracy and may cause the case to break resulting in bodily injury.
The measurement accuracy of the CO2 sensor can not be guaranteed for CO2
concentrations of 5,000ppm or more.

AC Adaptor
When measuring and recording over long periods of time, please
use a supplied AC adaptor.
Four AA Alkaline Batteries
If running on only batteries, the estimated battery life is about two
days. Keeping batteries in the unit allows a backup source of
power for when and if electrical power is cut from the AC adaptor.
As a Remote Unit, RTR-576 requires a Base Unit to carry out wireless
communication.
(Compatible Base Units: RTR-500, RTR-500NW/500AW, RTR-500DC)
• Note: When using batteries as a backup power supply, it is
recommended to replace them approximately once every two years to
avoid battery leakage.
Please set up the Base Unit first before the RTR-576.
Register Remote Units
Register RTR-576 as a Remote Unit by using the software supplied with the Base
Unit. After connecting an RTR-576 to your computer via USB cable, carry out
registration using your software: Settings Utility * - [Remote Unit Settings] Menu [Register] Button

Auto Calibration Function for CO2 Sensor Accuracy
What is "Auto Calibration" ?
Auto calibration is a function designed to enable long-term accurate measurements by
adjusting the lowest CO2 concentration measured in a certain period of time to the set
standard measurement in the air (atmospheric CO2 levels of 400 ppm).
• The factory default setting for auto calibration is enabled.
*1: To change settings, it is necessary to download "Adjustment Tools" application (free) from our website. Detailed info
can be found below.
*2: Manual calibration is expected to be performed no more than once a month. Operational procedures and other
reference info can be found below.
See:
For RTR-500 / 500AW / 500NW
Operation Guide] - [How to Use] - [Other Useful Functions] Menu
For RTR-500DC
[RTR-500DC Settings Utility Help] - [ How to Use] - [Basic Settings] - [Remote Unit Registration] Menu
*1: Make sure to use the data logger within the operating environment as listed in the specifications.
*2: When used in environments where temperature and humidity are over the values of 50°C 75%, 60°C 50%, 70°C 35%, and 80°C 25%,
sensor hysteresis may fluctuate by values greater than ±1.5%RH. Under certain circumstances, it may take some time to return to nor.
*3: Stated value is the measurement accuracy of the CO2 sensor when Auto Calibration is operating properly. A change in atmospheric
pressure directly influences the reading of CO2, which can cause measurement errors; a decrease in pressure by 10hPa result.
*4: Only “Endless” is available when using RTR-500W for Windows.
*5: Battery life varies depending upon the ambient temperature in which it is used, the recording interval, the frequency of communication, and
the battery performance. All estimates are based on operations carried out with a new battery and are in no way.
The specifications listed above are subject to change without notice.
This unit has been designed for private and/or industrial use only. It should not be used in
situations where strict safety precautions are necessary such as with medical equipment, or in
systems directly or indirectly connected with human life or well-being.
We shall not guarantee the unit's operation if it has been connected to a PC using a USB hub or
a USB extension cable.
Do not drop or expose the unit to a strong impact.
Do not cut or process the sensor cables. Also, do not twist, pull on or swing any of the cords.
To prevent damage to the unit from static electricity, remove static electricity from your body by
touching metal around you (such as a door knob and window frame) before touching the unit.
Place and store the unit and accessories out of the reach of children.
If the unit produces heat, emits smoke or a strange smell, or makes unusual noise, immediately
remove the batteries and stop using it.

Cautions about using the Temperature/Humidity Sensors
• If extremely severe temperature changes occur, the humidity measurements may appear
abnormal. Once the sensor's temperature becomes stable, the measurements will return to
normal.
• Do not connect the sensor to any data logger other than those specified by T&D Corporation.
• Do not expose the sensor to a strong impact. This may adversely affect measurement accuracy
and cause damage or malfunction.
• When the sensor is not to be used for a long period of time, please store it at normal
temperature and humidity.
• Do not use the sensor on the human body.
• Continued use may cause a decrease in the sensor’s accuracy and sensitivity even under
normal operational conditions. We suggest changing the THA-3001 after about one year of use.
If the sensor is being used in a bad environment (smoky or dusty places) it may be necessary to
change the sensor sooner.
• This sensor is not water resistant. Do not allow the sensor to become wet. If the sensor gets
wet, immediately remove the sensor from the unit and wipe it with a clean cloth as soon as
possible. Then allow the sensor to dry in normal room temperature before using it again.

When installing wireless communication devices take special care in selecting locations so as to ensure
proper communication. Note that even after a successful installation, due to changes in environmental
conditions, communication errors may occur when restarting the system.
Distributor's name
• As far as possible, try to keep wireless communication devices away from metals and set them up in high
unobstructed positions.
Address
• Please take note that in many instances, walls, floors, stairs, fences and desks will contain metals. In order to
carry out communication between indoor and outdoor units, please locate indoor units near a window so that
radio waves can be easily transmitted.
Phone No.
• Please install the Unit more than 30 cm away from walls or boards containing metal.

• If the Unit is placed in a metal container such as a freezer or refrigerator, the possible wireless communication
range will be shortened. In most cases radio waves are transmitted via doors and door openings so place the
Unit as near to doors as possible.
• As far as possible, keep the Unit away from noise-emitting sources.
• Equipment such as some industrial instruments, electronic devices or fluorescent lamps generate noise. Please
place the Unit more than 1 meter away from such devices.
• Please place the Unit more than 1 meter away from computers and other devices which emit noise.
• Keep all wires as far away from wireless communication devices as possible. Please be careful about placing
near any wiring or cables such as power supply cables, telephone wires or LAN cables.
• Objects which contain lots of water, such as plants or soil, absorb radio waves. We highly recommend that
such materials should not be placed between or near wireless communication units.
• When measuring temperature in a greenhouse it has been reported that as plants grew, communication errors
also increased.
