Elitech Tlog Series User Manual
Reusable Temperature and Humidity Data Loggers
Overview
The Elitech Tlog series data loggers are designed for monitoring and recording temperature and humidity for various products during storage and transport. They are suitable for applications across the cold chain logistics, including refrigerated containers/trucks, cooler bags, cooling cabinets, medical cabinets, freezers, and laboratories. These loggers are used for foods, pharmaceuticals, and other sensitive products.
The Tlog series features a built-in USB port, an LCD screen, and two buttons designed to prevent accidental presses. Users can view device status and parameters by pressing the buttons. The loggers allow customization of various parameters such as start/stop modes, multiple thresholds, and storage modes. Additionally, users can generate PDF reports directly from the device without needing the ElitechLog software.
The Tlog B100 series are Bluetooth-enabled versions, allowing operations via the Elitech mobile app without opening the package. This includes parameter configuration, data viewing, and Bluetooth printing, offering a simple, practical, and convenient user experience.

Operation
- Download & Install Software: Download and install the free ElitechLog software (available for macOS and Windows) from the official Elitech websites:
- Configure Parameters:
- Via ElitechLog Software: Connect the data logger to your computer via USB cable. Wait for the USB icon [U] to appear on the LCD.
- For default settings: Click 'Quick Reset' under the 'Summary' menu to synchronize the logger's time with your computer's local time.
- To change parameters: Navigate to the 'Parameter' menu, enter your preferred settings (e.g., start/stop modes, alarm thresholds, logging interval), and click 'Save Parameter' to apply them.
- Via Mobile App: Follow the steps outlined in the "App Operation" section above.
Warning! For first-time users or after replacing the battery, it is crucial to configure the logger's local time (using 'Quick Reset' or 'Save Parameter') to avoid time or time zone errors.
- Via ElitechLog Software: Connect the data logger to your computer via USB cable. Wait for the USB icon [U] to appear on the LCD.
- Start Logging:
- Press Button: Press and hold the left button for 5 seconds until the logging icon [▶] appears on the LCD, indicating the logger has started recording data.
- Auto Start: The logger begins logging immediately after being disconnected from the computer.
- Timed Start: The logger starts a countdown after disconnection and automatically begins logging at the pre-set date and time.
Note: If the logging icon [▶] keeps flashing, it signifies that the logger is configured with a start delay and will commence logging once the set delay time has elapsed.
- Mark Events: Double-click the left button to mark the current temperature and time. Up to 10 event marks can be recorded. After marking, the LCD will display "Mark", the number of marked groups, and "SUCCESS".
- Stop Logging:
- Press Button: Press and hold the right button for 5 seconds until the stop icon [■] appears on the LCD, indicating the logger has stopped recording.
- Auto Stop: The logger automatically stops when the maximum memory capacity is reached.
- Use Software: Open the ElitechLog software, navigate to the 'Summary' menu, and click the 'Stop Logging' button.
Note: Stopping via the physical button is the default setting. If this function is disabled in the software, you must use the 'Stop Logging' button within the ElitechLog software.
- Download Data:
- Without Software: Connect the logger to your computer via USB. A PDF report will be generated automatically. Locate and open the removable storage device named 'Tlog' and save the PDF report to your computer for viewing.
- Via ElitechLog Software: Connect the logger to your computer. The logger will auto-upload data to the ElitechLog software. Click 'Export' to select your desired file format (e.g., PDF, CSV, TXT) and save the data. If auto-upload fails, manually click 'Download' in the software and repeat the process.
- Re-use the Logger: To reuse a stopped logger, connect it to your computer. Ensure you have saved or exported the data first. Reconfigure the logger by repeating step 2 ('Configure Parameters'). After configuration, follow step 3 ('Start Logging') to begin a new logging session.
Warning! All previous logging data will be deleted upon re-configuration. If data was not saved, check the 'History' menu in the ElitechLog software.
- Repeat Start: For a stopped logger, you can quickly restart it without re-configuration by simply pressing and holding the left button.
Note: Always back up your data by repeating step 6 ('Download Data') before performing a 'Repeat Start', especially if not using the ElitechLog software.

Battery Replacement
The Tlog series uses a CR2450 3.0V button cell battery, which typically lasts for 2 years under normal storage and usage conditions. When the battery needs replacement, follow these steps:
- Ensure the logger is stopped and data has been downloaded.
- Carefully open the logger casing, usually by gently prying it open with a small tool or fingernail at a designated seam.
- Locate the CR2450 battery. Remove the old battery.
- Insert the new CR2450 battery, ensuring correct polarity (+/-).
- Close the logger casing securely.
- After battery replacement, it is essential to connect the logger to a computer or use the mobile app to reconfigure the local time and any other necessary parameters before starting a new logging session.
