(*1) When making recording settings via the cloud, recording will start as soon as communication occurs between the logger and T&D WebStorage Service. (Programmed start is not available)
(*2) Up to 16 characters (UTF-8)
(*3) Loggers issue warnings when a set limit is exceeded for the specified time period.
  • When T&D WebStorage Service receives a warning via the auto-upload function it will simultaneously issue an alarm notification via web browser and send out a warning report mail to the specified e-mail address that was set in the management screen of T&D WebStorage Service.

When connection fails...

  • When a communication error occurs between the logger and the access point try adjusting the placement and distance of the logger to the access point and make sure that all wireless LAN access point settings (SSID, Authentication method, Password, etc...) have been made correctly.
  • When a communication error occurs between the access point and the Internet check to make sure that an Internet connection can be established on the network you are using. (See if an Internet connection is possible using a PC or some other device that is connected to the same wireless LAN access point, hub, or router. See also, if the Internet connection is restricted by a firewall.)
    (For details see: Help - [TR-7wb/nw Series FAQ] - [Communication]- [I can't view the recorded data that was auto-uploaded to T&D WebStorage Service, what should I do?])

Adding Networks

The following describes four ways to add or change network access points.

Edit Network 1-3

Enter necessary information about wireless LAN connections (Network Name, Security and Password).
If necessary, fixed IP addresses and other settings can be entered here.

<Character Limit for SSID and Password>
Accepted Length
Network Name (SSID): Up to 32 characters
WEP : 5 or 13 characters / 10 or 26 digit hexadecimal value
WPA/WPA2 PSK : 8 to 63 characters / 64 digit hexadecimal value
Accepted Characters
0-9 a-z A-Z space ! # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~

Add by Search

The app will search for available nearby access points and display them in a list.
Select the desired access point and enter the password if necessary.

Add by WPS

If you are using a WPS-enabled wireless LAN access point, it is possible to connect by pressing buttons on both the logger and the access point.

  • Press down simultaneously on the <PWR> and <DISPLAY> buttons until appears in the logger display; this shows that the wireless LAN access point is in WPS authentication mode.

  • The availability of WPS and operations vary depending upon manufacturer and model of the access point being used. Please see the manual that came with the product being used.

Add from History

Select the desired access point from the archived list of previously used access points.

  • This is especially useful for adding multiple loggers to the same network and can be used for the second and all subsequent loggers.

Using Networks 1-3

Auto-upload Settings can be made for up to three wireless LAN connections (access points). The following describes how the auto-upload function will work in a situation where settings have been made for all three access points.

  1. First, the logger will attempt to connect to Network (SSID) 1. If the connection was successful, data will be uploaded without trying to connect to Networks 2 or 3.

  2. If the logger was unable to connect to Network 1, it will try connecting to Network (SSID) 2. If successful data will be auto-uploaded without attempting to connect to Network 3.

  3. If unable to connect to Network 2, the logger will try to connect to Network (SSID) 3. If the connection is successful data will be automatically uploaded, but if the connection was unsuccessful a communication error will be returned.

Example of Multiple Access Point Usage
  • Unsent recorded data will be gathered and sent together at the next scheduled auto-upload. However, if more than 8,000 readings have been recorded in Endless mode by the next transmission, overwritten old data cannot be sent. This means data stored on the T&D WebStorage Service or T&D Data Server has a missing data.

Other Settings Screen

Here it is possible to turn the Bluetooth Lock to ON or OFF and set a security passcode so that access is not available to other smartphones.
Time Settings
Settings for time difference and daylight savings time can be made here.
Data Destination
Select the destination for auto-uploading.
Temperature Unit
Use to switch between °C/°F.


Use this to activate/deactivate the Bluetooth Lock function.
To activate: Turn on Bluetooth Lock, enter a 6 digit passcode and tap [Apply] to send to the logger.

Other Settings Screen
To deactivate: Turn off Bluetooth Lock, and tap [Apply] to send to logger.
  • If the lock function has been activated and you wish to access the logger from another mobile device, please use the 6 digit passcode that was set. Once authentication has been successful, it will not be necessary the next time.
