nearby.
This unit is not water resistant. If water or a foreign object enters the case, immedi-
ately 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 precautions 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 fire or electrocution.
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 children.
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 specified by T&D Corpora-
tion.
Do not put anything on top of the cable. This may cause overheating.
Do not disconnect the USB cable during USB communication. Doing 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 batteries. If left in the
unit, the batteries may leak and lead to malfunctioning. 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 exposed to excessive heat or high
temperatures such as near fire or heating
equipment
• Areas exposed to static electricity
• Areas exposed to strong magnetic fields
• Areas exposed to dampness
• 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 specified 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 environment 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 directions from your com-
puter manufacturer.
• 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 insufficient contact due to age or vibration. This may lead to data loss.
• If the unit is not to be used for a long period of time, for safety reasons please remove the battery. If
left in the unit, the battery may leak and lead to malfunctioning.
• Please note that this document has been written based on the presupposition that details about con-
tracts with an Internet provider, specific network environments and the set-up of any other necessary
equipment to enable network connection has already been taken care of by the User and that con-
nection has been confirmed 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 specified by T&D Corporation.
• Make sure to use sensors within the measurement range indicated in the specifications for that
sensor.
• If extremely severe temperature changes occur, it may result in large errors in humidity measure-
ment. 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 tempera-
ture 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. If the sensor is being used in a smoky or dusty environment,
the surface of the sensor will accumulate impurities causing a further decrease in the sensor's
performance.
• The included 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 using the THA-3001 or THA-3151(option) in an environment where the humidity is under
30 %RH, the measurements may sometimes fluctuate. This is not abnormal.
• Do not expose to condensation, dampness, corrosive gases, or organic solvents (or insecticides
