DANGER To Prevent Serious Accidents
Do not disassemble, repair or modify the unit and/or acces-
sories.
Do not use the unit in any environment that is exposed to
chemicals and harmful gases. Doing so may cause corrosion
and/or other danger 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 ob-
ject enters the case, immediately remove batteries and stop
using it.
Do not touch the unit or AC adaptor during thunder and
lightning, as this may cause electrocution.
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 equip-
ment, 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 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 touch-
ing 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
speci 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.
Doing so may cause adverse eff ects 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. Leaving batteries inside the unit may cause battery
leakage and malfunction. Install new batteries when starting
or re-starting to use a unit.
For TR-75wb / TR-75nw: Ch.1 and Ch.2 terminals are NOT
electrically isolated from each other. Do not attach non-
isolated thermocouple sensors to objects connected to a live
voltage. This may cause a short circuit or an electrical shock.
CAUTION
Do not place or store in the following areas:
» Areas exposed to direct sunlight
» Areas subject to direct ames or heaters, as well as areas in which
hot air accumulates and creates extremely high temperatures
» Areas exposed to static electricity
» Areas exposed to strong magnetic 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 Precautions for Battery
» There is a risk of re or explosion if battery is replaced by an
incorrect type. Use and replace only with correct size and type (AA
alkaline) of battery.
» Do not disassemble, modify, mechanically crush or cut the battery,
as it may cause battery leakage, overheating, explosion or re.
» Do not dispose of a battery into re or a hot oven as this can
result in an explosion.
» Do not leave a battery in an extremely high temperature sur-
rounding environment or subjected to extremely low air pressure
that can result in an explosion or the leakage of ammable liquid
or gas.
CAUTION Other Precautions
» Use the unit in the speci 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 environment to another where there is a great diff er-
ence 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 computer manufacturer.
» We shall not guarantee the unit's operation if it has been con-
nected 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 insu 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 pro-
vider, speci c 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 connection has been
con rmed as workable. T&D Corporation shall not be responsible
for any damages which a contractor, a user or a third party may
suff er, whether direct or indirect, due to the inability to communi-
cate or use communication devices.
» Please be careful not to let a third party know of your registration
code. The registration code cannot be reissued or changed.
CAUTION Notices about Sensors
» Do not connect any sensor to the unit other than those speci ed
by T&D Corporation.
» Make sure to use sensors within the measurement range indi-
cated in the speci cations for that sensor.
» Do not connect the sensor to any data logger other than those
speci ed by T&D Corporation.
» Do not expose the sensor to a strong impact. This may adversely
aff ect 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.
» The included sensor is not water resistant. 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.
» 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 temper-
ature becomes stable, the measurements will return to normal.
» The temperature-humidity sensors will with normal use experi-
ence losses in precision and sensitivity over time due to degrada-
tion. If the sensor is being used in an unsuitable environment
(smoky or dusty places) it may be necessary to change the sensor
sooner.
» When using the sensor in an environment where the humidity is
under
30 %RH, the measurements may sometimes uctuate. This is
not abnormal.
» Do not expose to condensation, dampness, corrosive gases, or
organic solvents.
Thermocouple Sensors
» We do not handle the sale of Thermocouple sensors. Please pre-
pare a commercially available sensor.
