Getting Ready

Set up a T&D WebStorage Service Account

T&D WebStorage Service is a cloud service to store data recorded by T&D data loggers. The stored data can be accessed for viewing and downloading via PC and smart phone from anywhere, anytime.
By using T&D WebStorage Service with the T&D Thermo app, data retrieved by the app can be sent to T&D WebStorage Service, and data stored in the WebStorage Service can also be accessed from T&D Thermo.

1. Install T&D Thermo on your mobile device and open it.

   Tap [OK] to allow Bluetooth access.

   

2. Tap the Menu icon () - [Account Management].

   

3. Tap [Selected Account].

   

4. If you do not already have a T&D WebStorage Service account, create one by tapping [Get a user ID]. (Follow the messages as they appear on screen.)
   If you already have an account, enter the User ID and Password and tap [Apply].

   

   Multiple accounts can be added and switched.

5. Tap the () icon in the upper left corner of the screen to go back to the home screen and add a device. (Refer to [Add a Device to the App] below.)

   If there are devices already registered to the account, they will be displayed in the device list on the home screen.

Add a Device to the App

1. Tap the [+ Add] Button in the lower right corner of the home screen to open the Add Device screen.

   

2. The serial number and registration code are required to register the device. By selecting the desired device in the list of Nearby Bluetooth Devices, its serial number will be entered automatically.
   Or you can directly enter the serial number.
   

3. Enter the registration code (that can be found on the label supplied with the product) and tap [Apply].

   

   If you have lost the registration code label, see: TR4A Series FAQ - [Device / Power / Sensors] - [Q. Where can I find the Registration Code and Serial Number?]

4. When adding multiple loggers, repeat the process one unit at a time.

   Tap to go back to the home screen.
   
   

Collecting and Viewing Data

Data Collection

The following describes the procedure for collecting and saving recorded data from devices using Bluetooth communication.

1. Select and tap the device in the list to open the Device Info screen.

   

2. Tap Bluetooth() to connect with the device.

3. The app starts collecting data from the logger and plots a graph.

   The collected data is sent to the T&D WebStorage Service account.

   

4. If necessary, proceed with Report Creation(), Download(), and Device Settings.

Graph Display and Operation

The collected data will be displayed in a graph.

By rotating your mobile device, the graph will go into landscape mode.

[Download] Button

Tap this to download the data to your smartphone or tablet. All data recorded by the logger since the previous download will be stored as a new file and can be found in the File List.

• If you quit the application or go back to the previous screen without downloading, the data will not be saved on your mobile device and you will need to open the graph again if necessary.

[Graph Settings] Button

Tap this to view or change the Graph Display Count setting.
You can select to display 1000, 2000, 4000, 8000, 16000 readings or All data in the graph.

• Default setting is 16000 readings.
• See: [Recording Settings] - [Estimation of time until [FULL] is displayed]

Moving Vertical Cursor

A long press on the graph in full screen mode will bring up a vertical cursor.

• Slide right and left to move the cursor.
• The screen will show the date, time, and readings for the cursor position.

Moving Horizontal Cursor

Slide up and down to move the cursor (in landscape mode).

Zoom in and out

Pinch in or out anywhere on the graph (in portrait/landscape mode).

Report Creation and Output

Here you can create a data report in PDF format. The report can then be printed, saved or shared via email or apps that can handle PDF files.

Tap () to open the Report Settings screen.
Make the necessary settings and tap [Create] to create a report.

Title

Optional (up to 30 characters)

• If empty the title will be [Report for Device Name].

Output Channel(s)

Select the channel(s) to output to the report. A separate file will be created for each channel.

Upper Warning / Lower Warning

Turn on and set the limit value(s) if desired.
The report will show the total time above/below limit and judgment whether there are any out of limit values. (Also shown by the colored lines on the graph.)

• This setting is used to show if measurements in the report are within specified range, and does not function as a warning notification.

Report Sample

Print, Email, Share, or Save a Report

Select the output option for the generated report.
If you exit the app or go back to the previous screen without saving the report, data will be lost. You will need to create a report again.

Using Adjustment Function

When using the adjustment function, measurements are displayed and recorded after being adjusted according to the conditions set by the user.

1. Tap [Bluetooth] from the device info screen to open the Graph and Settings Menu, where you can check or change the settings via Bluetooth.

   If a recording is in progress, stop recording first before you proceed. (From the [Rec Settings] menu, tap [Stop] to stop the recording.)

2. Tap [Other Settings].

3. Under [Adjustment], tap the channel to which you wish to make adjustments.

   If you wish to make new adjustments on an already adjusted channel, it is recommended to tap [Initialize] to reset the settings first. (Initialized setting: y=1x+0)

4. Select the adjustment method (1 Point Adjustment or 2 Point Adjustment), make adjustment entries, and then tap [Apply]. (Refer to Adjustment Entries and Guidelines)

5. Start recording from the [Rec Settings] menu.

   The adjustment equation can also be found in the [Settings Table].

Adjustment Entries and Guidelines

The adjustment equation y=ax+b is determined by the adjustment entries. (x: Measurement Value, y: Post-adjusted Value)
An equation with a slope (a) and/or an intercept (b) exceeding the following ranges cannot be set.

		Temperature, Humidity
Slope (a)	Range	0<a≤2
	Significant Digits	3 decimal places
Intercept (b)	Range	within ±30 °C within ±30 %
	Significant Digits	same as that of the data logger's measurement resolution

There are two possible methods of adjustment:
1 point Adjustment (Use when measuring in a range of ±20 °C)
2 point Adjustment (Use when measuring in a wide range).

1 Point Adjustment

Use this to adjust all measurements with the same offset. (The whole graph will be adjusted up or down, keeping the same slope.)
This adjustment method changes only the intercept (b) where the slope (a) is considered to be the value of "one".

For example, the Remote Unit is measuring 10.2 °C, but the standard says the actual measurement should be 10 °C

Enter 10.2 in the "Before" box and 10 in the "After" box.
The conversion equation will be y=x−0.2 and for all measurements an adjustment to the offset of −0.2 will be made.

2 Point Adjustment

Use this to adjust measurements in a wide range or when adjustment cannot be carried out using only one point. The slope will change.
The adjustment equation will be calculated from two points: the slope (a) and the intercept (b).

For example, the data logger is measuring 0.2 °C and 9.6 °C, but the standard says the actual measurements should be 0 °C and 10 °C.

Enter 0.2 and 9.6 in the "Before" boxes and 0 and 10 in the "After" boxes.
In this case the slope (a) is (10−0)/(9.6−0.2)=1.06.
The conversion equation is y=1.06x−0.213 with the intercept being −0.213.
