Making Warning Settings

By using Auto-upload and Warning Settings, it is possible to monitor for warnings on the server (T&D WebStorage Service / T&D Data Server), and to receive warning notifications by email.

Also, the [ALM] icon on the TR7A display notifies the user of the occurrence of a warning.

Note

Warning notification methods and conditions for warnings/recovery may differ depending on the device model and data destination server. Please refer to [Specifications for Warning Transmission] for details.

[Warning Settings] Tab

Only checked items will be monitored for warning.

Note

  • When there are multiple device icons in the Connected Devices box, select the one for which you wish to make settings.
  • Warning settings can also be changed from T&D WebStorage Service or T&D Data Server.
[Send Settings] Button This will send the settings to the connected device.
[Get Settings] Button This will retrieve the current settings from the connected device. This can be used to apply the same settings to multiple devices as shown below:
  1. After getting the settings from device A, disconnect the USB cable from A and connect it to device B.
  2. Click [Send Settings] to apply the settings to device B.
Upper Limit / Lower Limit The checked items will be monitored for warning. Enter numeric values for each channel.
  • The entered limit values are not included in the warning range.
  • When downloading recorded data from the [Download Data] tab, you can check the total time out of range (upper/lower limits) in the Download Summary.
  • With the TR7A, the [ALM] icon flashes on the LCD during a warning condition.
Sensor Warning Select "ON" in order to monitor for sensor errors (No sensor connected, improper connection, damaged, etc.)
  • When downloading recorded data from the [Download Data] tab, you can check the total time of sensor error in the Download Summary.
  • With the TR7A, the [ALM] icon flashes on the LCD during a warning condition.
Warning Judgment Time When an out-of-limit condition or sensor error continues for the set length of time, a warning will be judged to have occurred.
  • If the condition recovers within the judgment time, it is not regarded as a warning.
  • For the TR71A/75A in Vaccine Mode, this setting is not available. (Warnings will be generated immediately when thresholds are exceeded.) The warning occurrence is judged based on the recording interval set in the [Start Recording] tab. To quickly detect the out-of-limit condition and sensor error, set a shorter recording interval.
Battery Warning Select "ON" if you wish to receive a warning notification when batteries need to be replaced.
(TR-7wf is not supported)
  • TR7A loggers: Recorded data will be retained even if battery power is completely gone. The [ALM] icon will not appear on the LCD.
  • TR-7wb/nw/wf loggers: Continuing to use the unit without changing the batteries could lead to loss of recorded data.
  • For TR-71nw/72nw(-S/-H), the firmware version needs to be 1.11 or higher, and 1.04 or higher for TR-75nw. *1
  • The battery warning mark (), which appears on the logger’s LCD when it is time to replace the batteries, will blink or light up depending on the model. *2
*1: For how to check your firmware version, refer to [Q&A about TR7 Series Devices] - [Q12: How can I check my firmware version and update it when necessary?]
*2: For the estimated battery life, refer to [Q&A about TR7 Series Devices] - [Q13: What is the battery life for the data loggers?]

[ALM] Icon Display Examples (TR7A)

For the TR7A with upper/lower limit and/or sensor warning checked in the Warning Settings, the [ALM] icon will flash on the LCD screen when a warning is detected.

Note:

Note, however, that when the TR71A/75A in Vaccine Mode has an Upper or Lower Limit Warning, the [ALM] icon will not disappear until you clear the display.

Upper / Lower Limit Warning

Sensor Warning

When a measurement cannot be performed due to disconnection or malfunction of the sensor, the readings on the LCD will be shown as [--.-]. If the sensor warning setting has been set to ON, [ALM] will also flash.
In TR71A, even if the external sensor connected to Ch1 fails, the internal sensor for Ch1 will continue to measure uninterrupted and no error will be shown.

EX: Sensor Error in Ch2 (TR71A)

Upper / Lower Limit Warning Details

Use the DISPLAY button to switch the display to check which limit (upper or lower) has been exceeded.
(Refer to LCD Display Pattern in [Note]).

EX: TR71A/75A Ch2

Switch to the fixed display of Ch2 MAX/MIN values and check the position of the [ALM] icon.
If it appears next to [Max], it is an upper limit warning. If next to [Min], then it is a lower limit warning.

Clearing the ALM Icon (TR7A)

If you start a new recording session or change the warning settings while the device is in a warning state, the ALM display will disappear and you will receive a notification (Warning status: Warning Lifted).

The following explains how to turn off the display manually while the recording continues. After the operation, you will receive a notification (Warning status: Back to Normal).

Using the "TR7 for Windows" Software:

Connect the device to your PC via USB, and go to [Communication] Menu - [Clear ALM Display].

Using the DISPLAY Button on the Device:

  1. With each pressing of the DISPLAY button, the item on the display will change.
    When the desired display pattern (ALM/Max/Min) appears, stop pressing the button.
  2. Press-and-hold the DISPLAY button until the ALM icon disappears.
    The Max/Min values will also be cleared.
  3. Return to the original display by pressing the DISPLAY button again.

In addition to using the "TR7 for Windows" software and the DISPLAY Button on the device, you can also use the "T&D Thermo" app to clear the ALM display manually. (For details, refer to the Help of T&D Thermo)

Note:

LCD Display Pattern
Ch1/Ch2 current values (fixed) → Ch1 MAX/MIN values (fixed) → Ch2 MAX/MIN values (fixed) → alternating display (for 2 seconds each)
The factory default setting is a fixed display of Ch1/Ch2 current values.
