  • Places where water and oil will not be in contact with the device and sensor
  • Places that are not affected by smoke, dust and condensation
  • Places where Bluetooth Communication can be carried out without interference.
  • Places where there is access to the WLAN/LAN (for auto upload of recorded data to T&D WebStorage Service or T&D Data Server)
  • Places where it is easy to collect the device (for downloading data to a PC via USB connection)
  • Places where it is possible to carry out button operation on the logger (TR-7wb/wf only; for WLAN direct communication with a mobile device)
Do the included and optional sensors lose precision over time?
Temperature Sensor
Although the sensor element of the temperature sensor does not usually experience loss of precision due to use over time, losses in precision will occur due to external factors, such as build up of water.
If you experience losses in measurement precision, we suggest the purchase of a new sensor.
Temperature-Humidity Sensor
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.
Can the device be used worldwide?
The wired LAN devices can be used in all areas and countries throughout the world.
The wireless LAN devices have been designed to comply with rules and regulations defined by the following regulating bodies.
FCC (USA), IC (Canada), CE (EU), ARIB (Japan)

I cannot properly make Wireless LAN Settings using WPS, what should I do? (For Wireless LAN type (wb/wf))
Check the following:
  • Check whether the wireless LAN access point is compatible with WPS.
  • Check to make sure [WPA2-PSK (AES) or No security] has been selected. If [WEP (64bit / 128bit) and WPA-PSK (TKIP)] has been selected WPS cannot be used.
  • Try adjusting the position of the device (move it closer to the access point)
  • If you are using an access point which uses other forms of authentication such as AOSS, make sure that only WPS is activated.
  • If the Wireless LAN Access Point's MAC address filtering feature is set to active, it is necessary to first register the MAC address(*1)of the device being used.
  • Using T&D Thermo, communicate via Bluetooth or WLAN Direct Communication to make Wireless LAN Settings(*2).
(∗1)MAC address information for the logger can be found by using either Bluetooth or WLAN Direct Communication and checking in the [Network Settings] section below the Graph which opens upon communication.
(∗2)Below the Graph which opens upon communication, make sure that under [Network Settings] that [Wireless LAN] is activated (turned ON).
