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.

For TR-75wb / TR-75nw: Ch.1 and Ch.2 terminals are NOT electrical-

ly 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.


» Areas exposed to direct sunlight

» Areas subject to direct flames 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 fields

» 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.


» 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 bath-

About TR-71wb / TR-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-75wb / TR-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.

Compatible Wires

Single wire:

0.32 to

Twisted wire: 0.08 to 0.32

» 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 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.

position that details about contracts 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 connection 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.


Notices about Sensors

» Do not connect any sensor to the unit other than those specified by T&D


» Make sure to use sensors within the measurement range indicated in the

specifications for that sensor.

» 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.

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, imme-

diately 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 tempera-

ture before using it again.

» When using the sensor 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


Thermocouple Sensors

» We do not handle the sale of Thermocouple sensors. Please prepare a

commercially available sensor.
