3.2. Software Installation (Elitechlog)
To configure advanced parameters and manage data, download the Elitechlog software from the official Elitech website. The software is available for both Windows and Mac operating systems. Follow the on-screen prompts to complete the installation.
Video 2: This video provides a guide on installing and using the Elitechlog software, which is essential for advanced configuration and data management of the Tlog 10EH data logger.
3.3. Connecting to Computer & Parameter Setting
Connect the Tlog 10EH to your computer via the USB port. Open the Elitechlog software. Navigate to the 'Parameter' or 'Settings' tab. Here, you can set the logging interval, start mode (immediate, button press, or timed start), temperature unit (°C/°F), alarm limits (upper and lower), and enable/disable features like button stop, temporary PDF generation, and circular logging. Remember to save your parameters after making changes.

4.2. Data Visualization on Screen
Briefly press the 'Start' button to cycle through the display menus. You can view the current temperature, the number of logged readings, current time, current date, maximum temperature recorded, and minimum temperature recorded.
4.3. Automatic PDF Report Generation
Once logging is complete, simply plug the Tlog 10EH into a USB port on your computer. The device will automatically generate a PDF report containing all logged data, including a graph and summary. No special software is required to view this report.
