4. Operating Instructions
4.1 Starting the Logger
To begin temperature logging, press and hold the green START button on the device. The green ACTIVE LED will flash every 12 seconds, confirming that the logger is actively recording data. The logger is capable of recording data for up to 85 days, depending on its configuration.
4.2 Monitoring Status
The logger provides visual feedback through its LED indicators:
- Green ACTIVE LED: Flashes every 12 seconds when logging is active and within normal parameters.
- Red ALARM LED: Flashes if the recorded temperature has exceeded or fallen below the pre-set high or low temperature thresholds.
5. Data Retrieval and Reporting
The FlashLink Mini PDF Logger generates automatic PDF and CSV reports when connected to a computer, eliminating the need for proprietary software installation.
5.1 Retrieving Data
- Carefully remove the protective cap from the USB connector.
- Plug the logger directly into a standard USB port on a computer or compatible tablet.
- The logger will be recognized as a removable drive. A window will typically open automatically, providing access to the generated PDF report and CSV data file.
5.2 Viewing Reports
The logger automatically generates a comprehensive PDF report and a CSV file containing all recorded temperature data. These reports can be viewed and saved on any PC or tablet with a standard PDF viewer and spreadsheet software.

6. Maintenance
The FlashLink Mini PDF Logger is a single-use device and requires minimal maintenance. To ensure proper function and longevity before use, keep the device clean by wiping it with a dry, soft cloth. Always ensure the protective cap is securely in place over the USB connector when the logger is not connected to a USB port to prevent dust or damage.
7. Troubleshooting
- Logger not starting: Ensure the START button is pressed and held firmly until the green ACTIVE LED begins to flash. If the logger still does not activate, the internal battery may be depleted, or the unit may be faulty.
- No data when connected to PC: Verify that the logger is fully and correctly inserted into the USB port. Try connecting to a different USB port or another computer. If the green ACTIVE LED was not flashing during the trip, the logger may not have started recording or may have stopped prematurely.
- Alarm LED flashing: A flashing red ALARM LED indicates that the temperature recorded during the trip has exceeded or fallen below the pre-configured high or low temperature thresholds. Refer to the generated PDF report for detailed information on specific alarm events and their duration.
