What is a difference between Normal and Vaccine Mode for TR71A/75A?
It is a measurement mode compliant with the directives on vaccine management laid out by the United States Center for Disease Control.

TR71A/75A models are designed with vaccine mode.
You can change this setting by opening the logger's Setting Menu via Bluetooth and going to [Rec Settings] - [Measurement Mode].

Operational differences by mode are as follows:

Normal Mode Vaccine Mode
Max/Min Values Max/Min temperature reading since the start of recording or reset (via buttons or software/app) Max/Min recorded value since the start of recording or reset (via buttons or software/app)
Warning Judgment Time 30 sec to 60 min (9 selections)
A warning will be issued when a measurement exceeds the set threshold value or a sensor error occurs for longer than the set judgment time.		 0 sec.
If a recorded value exceeds the set threshold value or if a sensor error occurs, a warning will be issued.
Warning Display
[ALM] Icon		 Warning alarms for exceeding a set upper and lower limit and for sensor errors will both disappear when the warning condition is resolved. Warning alarms for exceeding a set upper and lower limit will not disappear even after a value returns to within the threshold range.
Warning alarms for sensor errors will disappear upon return to normal.
What is the battery life for the data loggers?

Estimated battery life is as follows:

  TR71A / 72A / 75A, TR-71wb / 72wb TR-71nw / 72nw TR-75wb TR-75nw
Conditions: Auto-upload interval:
· Auto-Upload ON
· Bluetooth ON (A/wb)
· Rec interval 10 sec or more		 1 min Approx. 10 days
10 min Approx. 2 months
1 hour Approx. 12 months Approx. 10 months Approx. 7 months
12 hr or more Approx. 15 months Approx. 18 months Approx. 12 months
Battery life varies depending upon multiple factors including frequency of communication, LAN 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.
Shown above is the estimated battery life with Auto-Upload and Bluetooth (A/wb) ON. Battery life can be extended 1.2 times by going to [Bluetooth Communication Settings] in TR7 for Windows and turning OFF Bluetooth communication.

If you wish to measure over a long period of time, please use an external power supply.

  • USB Bus Power 5V 200mA
  • AC Adapter USB Mini-B Type (option AD-05A2 or AD-05C2)
  • PoE IEEE 802.3af (for TR-7nw)

Battery Warning Mark and Warning Mail Transmission
A warning report mail will be sent when the Battery Warning is enabled in Warning Settings and a low battery condition is detected (when the battery warning mark blinks or lights up on the device LCD). See below for details.

TR7A BLINKING: Low battery indication (warning mail transmission)
ON: Auto-upload of recorded data will stop. (Recording will continue.)
TR-7wb/nw ON: Low battery indication (warning mail transmission)
If the battery is left unchanged until the LCD display goes blank, all recorded data in the logger will be lost.
TR-7wf ON: Low battery indication (NO warning mail transmission)
If the battery is left unchanged until the LCD display goes blank, all recorded data in the logger will be lost.
  • Regardless of whether the warning setting is ON or OFF, you can check the battery status at any time via the mobile app T&D Thermo or a web browser (T&D WebStorage Service / T&D Data Server).
Where can data loggers be placed?
They can be placed in a variety of locations depending on the purpose for recording data. We suggest placing it in environments which satisfy the following conditions.
  • 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)
Readings from the internal temperature sensor (or the thermocouple) are incorrect, what may be the problem?

Internal Temperature Sensor (TR71A, TR-71wb/71nw/71wf)
Devices themselves generate heat and this effects internal sensors. Depending upon the frequency of auto-transmission communications an increase of up to 0.3°C may occur. Especially when an external power supply is being used, measurements may increase significantly. In such cases, we recommend using an external sensor.

Thermocouple Temperature (TR75A, TR-75wb/75nw/75wf)
Please make sure that the actual sensor being used matches the settings found in "T&D Thermo" under [Recording Settings] or in "TR7 for Windows" - [Recording Start] Tab - [Sensor Type Settings].
If measurements are unstable while using external power (USB or PoE), connect to the GND terminal.

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.
  • US Model (FCC, IC)
  • EU Model (CE)
  • Japan Model (ARIB)

Usage in countries or areas which follow regulations other than those defined by the above bodies is illegal.

This indicates that the connection is successful. Check the following:

  • Check to make sure that the REC mark () in the LCD of the device is on.
    (Recorded data will not be uploaded when recording is not in progress.)
  • Make sure that the T&D WebStorage Service account which was used to register this device is the same as the one currently logged in.

BLINKING:
This indicates that the connection to T&D WebStorage Service is failing. Check the following:

  • If you entered the IP address, subnet mask and other settings, please make sure that the entries are all correct.
  • 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.)
  • When using a proxy server is necessary, make sure that the address of the proxy server and the port number are set correctly in the Auto-upload Settings of "TR7 for Windows".
    (A proxy server that requires authentication cannot be used.)
  • Check to make sure that T&D WebStorage Service is not temporarily down due to maintenance or other trouble; try accessing T&D WebStorage Service from your web browser.
How much data can be stored in the T&D WebStorage?

For the data uploaded automatically from the logger (via Auto-upload):
The maximum amount of data that can be stored in the T&D WebStorage Service varies depending on the recording interval set for the logger. After the storage period expires, the data will be automatically deleted.

For the data sent manually via T&D Thermo (from the File List of downloaded files):
There is also a limit to the amount of data that can be stored. When the limit is exceeded, the oldest data will be deleted automatically.

For details about the storage capacity, refer to the T&D WebStorage Service Details.

Please use our Windows Software T&D Graph for downloading and storing a backup of your cloud data.

Is it possible to share data between multiple users of T&D WebStorage?
It is possible when using a web browser to share data by creating a Read-Only account.
  • With a Read-Only account it is possible to view data but it is not possible to delete data or make any settings changes.
  • Visit T&D WebStorage Service, go to [Account] > [Read-Only Account Setting] and set the Read-Only ID Password.
Is it possible to increase the number of e-mail addresses or change the recipient address depending on the name of the Remote Unit or the type of warning?

With T&D WebStorage Service, it is not possible to increase the number of recipients or filter and send using specific conditions. But if you set the address to a cloud-compatible mail service (Gmail, Outlook, etc.), the filtering function of that mail service can be used and mail can be forwarded to more addresses. Since forwarding is not done via a PC, you can use it as if you were increasing the number of recipients.

Also, if you specify an e-mail address with the filter function of the e-mail service and create a filter using a specific word such as the name of the installation location, Remote Unit name, or type of warning, it is possible to send mail to a specific address depending upon the set conditions.
 Note

The types of warning are explained in [T&D WebStorage Service]-[Alert View]-[Warning Status Report] in this Help.
