Make sure to use new batteries (including for replacement) and insert in the correct direction.

Battery Installation & Sensor Connection

About TR71A Internal Sensor

Channel 1 has an internal temperature sensor. When an external sensor is not connected, the internal sensor will be used.

About TR75A 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: Φ0.32 to Φ 0.65 mm (AWG 28-22)
Twisted wire: 0.08 to 0.32 mm2 (AWG 28-22)
Diameter: 0.12 mm or more
Strip length: 9 to 10 mm

Wiring Connections

Using GND

If measurements are unstable while using external power (USB), connect to the GND terminal.

Sensor Type Setting

Set the sensor type in the software. (TR7 for Windows – [Start Recording] tab)

Symbol | 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 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 Corporation.

| Do not disconnect the USB cable during USB communication. Doing so may cause adverse effects to the unit and/or PC.
Symbol | 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.
Symbol | 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.
Symbol | 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 restarting to use a unit.
| For TR75A: 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.

Do not place or store in the following areas

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.

Precautions for Battery

There is a risk of fire 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 fire.
Do not dispose of a battery into fire or a hot oven as this can result in an explosion.
Do not leave a battery in an extremely high temperature surrounding environment or subjected to extremely low air pressure that can result in an explosion or the leakage of flammable liquid or gas.

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 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.
Please note that this document has been written based on the presupposition 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.
Please be careful not to let a third party know of your registration code. The registration code cannot be reissued or changed.

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.
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.
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 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.
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 solvents.

Thermocouple Sensors

We do not handle the sale of Thermocouple sensors. Please prepare a commercially available sensor.

We do not handle the sale of Thermocouple sensors. Compatible wire sizes are as follows. Single Wire : Ø0.32 to Ø0.65 mm (AWG 28 – 22), Twisted Wire : 0.08 to 0.32 mm2 (AWG 28 – 22), Ø0.12 mm or more in diameter, Stripping Length : 9 to 10 mm
When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C. When using external power, the data logger itself generates heat and the internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case.
When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20°C.
Vaccine mode complies with the CDC (Centers for Disease Control and Prevention) requirements for vaccine management.
Client function. HTTP(S) proxy supported.
Battery life in the table above is for two AA Alkaline type batteries, and varies depending upon multiple factors including frequency of communication, network environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
