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 insert any foreign objects into any of the units' jacks.
»
If the unit gets dirty, wipe it with a clean cloth.
»
Make sure to remove dust and dirt from plugs of any cables.
»
Battery terminals may provide insuf
fi
cient contact due to age or vibration. This
may lead to data loss.

Please note that this document has been written based on the presupposition
that details about contracts with an Internet provider, speci
fi
c network environ-
ments and the set-up of any other necessary equipment to enable network
connection has already been taken care of by the User and that connection has
been con
fi
rmed as workable. T&D Corporation shall not be responsible for any
damages which a contractor, a user or a third party may suffer, whether direct or
indirect, due to the inability to communicate or use communication devices.
CAUTION
Notices about Sensors
»
Do not connect any sensor to the unit other than those speci
fi
ed by T&D Corpo-
ration.
»
Make sure to use sensors within the measurement range indicated in the speci
fi
-
cations for that sensor.
»
Do not connect the sensor to any data logger other than those speci
fi
ed by T&D
Corporation.
»
Do not expose the sensor to a strong impact. This may adversely affect measure-
ment accuracy and cause damage or malfunction.
»
When the sensor is not to be used for a long period of time, please store it at nor-
mal temperature and humidity.
»
Do not use the sensor on the human body.
Temperature-Humidity Sensor
»
If extremely severe temperature changes occur, it may result in large errors in
humidity measurement. Once the sensor's temperature becomes stable, the
measurements will return to normal.
»
The temperature-humidity sensors will with normal use experience losses in
precision and sensitivity over time due to degradation. If the sensor is being
used in an unsuitable environment (smoky or dusty places) it may be necessary
to change the sensor sooner.
»
The included sensor is not water resistant. If the sensor gets wet, immediately re-
move 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 using the THA-3001 or THA-3151(option) in an environment where the
humidity is under 30 %RH, the measurements may sometimes
fl
uctuate. This is
not abnormal.
»
Do not expose to condensation, dampness, corrosive gases, or organic solvents
(or insecticides for High Precision Temperature-Humidity Sensors)
Optional Sensors
»
We offer a wide range of Temperature and Temperature-Humidity sensors, sensor
extension cables, AC adaptors, etc. For details see the Optional Products infor-
mation on the Product Page.

DANGER
To Prevent Serious Accidents
Do not disassemble, repair or modify the unit and/or accessories.
Do not use the unit in any environment that is exposed to chemicals
and harmful gases. Doing so may cause corrosion and/or other dan-
ger to the unit. Also, coming in contact with hazardous substances
may cause bodily harm to the user or people nearby.
This product is not water resistant. If water or a foreign object enters
the case, immediately remove batteries and stop using it.
Do not handle the unit, remove batteries or cables with wet hands.
This product has been designed for private and/or industrial use
only. It should not be used in situations where strict safety precau-
tions are necessary such as with medical equipment, or in systems
directly or indirectly connected with human life or well-being.
Do not drop or expose the unit to a strong impact.
Do not connect any communication cables connected to the unit to
telephone line outlets. Continued use may cause
fi
re or electrocu-
tion.
Do not cut or process the cords for the communication 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 chil-
dren.
We are not responsible for any damage, malfunction or trouble,
whether direct or indirect, caused by the use of our product.
Do not use any battery, sensor, or cable other than those speci
fi
ed
by T&D Corporation.
Do not put anything on top of the cable or the unit. This may cause
overheating.
Do not disconnect the USB cable during USB communication. Do-
ing so may cause adverse effects to the unit and/or PC.
Make sure that sensor and cable plugs are all inserted fully, so as
not to cause an improper connection. Also, when unplugging the
cable from the unit, do not pull the cord, but hold the connector to
disconnect.
If the unit produces heat, emits smoke or a strange smell, or makes
unusual noise, immediately remove the batteries and stop using it.
Also, unplug the unit from the PC.
If the unit is not to be used for a long period of time, remove batter-
ies. Leaving batteries inside the unit may cause battery leakage
and malfunction. Install new batteries when starting or re-starting
to use a unit.
CAUTION
Do not place or store in the following areas:
»
Areas exposed to direct sunlight
»
Areas subject to direct
fl
ames or heat-
ers, as well as areas in which hot air
accumulates and creates extremely
high temperatures
»
Areas exposed to static electricity
»
Areas exposed to strong magnetic
fi
elds
»
Areas exposed to water leakage
»
Areas subject to condensation or
wet areas
»
Areas exposed to excessive
vibration
»
Areas exposed to excessive
smoke, dust or dirt.
CAUTION
Other Precautions
»
Use the unit in the speci
fi
ed operating environment. Do not use it for any purpose
other than for which it was designed.
»
Condensation may occur inside the case when a unit is moved from one environ-
ment to another where there is a great difference in temperature.
»
Do not use the unit in wet areas or places exposed to water such as bathroom.
»
When connecting the unit to your PC, make sure to follow all warnings and direc-
tions from your computer manufacturer.

About TR-71wf / 71nw Internal Sensor
Channel 1 has an internal temperature sensor. When an external sensor is not connected, the
internal sensor will be used.
About TR-75wf / 75nw Input Terminal
When connecting thermocouple wires to the input terminal, make sure that the positive and
negative connections are in the proper order. If the polarity is incorrect, changes in temperature
will be reversed (when the real temperature increases, the measured temperature will decrease).
Wiring Connections
Connect and disconnect the thermocouple wire from the
hole while pressing the input terminal button with a
screwdriver or other such tool.
Do not try to pull out the wire without pressing the button.
