4. Setup

1. Battery Installation: The device requires an ER14250 battery (not included). Open the battery compartment, insert the battery with the correct polarity, and securely close the compartment.
2. Software Installation (Optional): While the device can generate a report directly, for advanced configuration and data analysis, it is recommended to install the dedicated software. Insert the data logger into a computer's USB port. The device may appear as a removable drive containing the software installer or a link to download it. Follow the on-screen instructions for installation.
3. Initial Configuration:
   • Connect the data logger to a computer via USB.
   • Open the installed software.
   • Configure parameters such as logging interval, alarm thresholds (if applicable), start delay, and logging mode (e.g., cycle recording).
   • Save the configuration to the device.

5. Operating Instructions

1. Starting Data Logging:
   • After configuration, disconnect the data logger from the computer.
   • Press and hold the button on the device for approximately 3 seconds until the green indicator light flashes, indicating logging has started.
   • The LCD will display current temperature and humidity readings, along with logging status.
2. Monitoring Readings: The LCD screen continuously displays the current temperature and humidity. The status indicator (red/green) provides visual feedback on the device's operational status and any alarms.
3. Stopping Data Logging:
   • To stop logging, press and hold the button for approximately 3 seconds until the red indicator light flashes, or until the logging stops automatically based on configured settings (e.g., full memory).

6. Data Retrieval

1. Connect to Computer: Remove the protective cap and insert the data logger into an available USB port on your computer.
2. Automatic Report Generation: The device will typically generate a PDF or Excel report automatically upon connection, containing all recorded data. This report can be saved and viewed.
3. Using Software: For more detailed analysis, open the dedicated software. The software will detect the connected logger and allow you to download the raw data, view graphs, export data in various formats, and generate customized reports.

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace the ER14250 battery when the low battery indicator appears on the LCD or when the device fails to power on. Ensure correct polarity during installation.
• Storage: Store the data logger in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Ensure the protective cap is securely in place.
• Sensor Protection: Avoid exposing the sensor to corrosive gases or liquids, which can affect accuracy and device lifespan.

8. Troubleshooting

• Device Not Turning On:
  • Check battery installation and polarity.
  • Replace with a new ER14250 battery.
• No Data Logging:
  • Ensure logging was properly initiated by pressing the button until the green indicator flashes.
  • Verify that the device memory is not full. If full, download data and clear memory if cycle recording is not enabled.
  • Check configuration settings via software to ensure a logging interval is set.
• Cannot Connect to Computer / Download Data:
  • Ensure the USB connection is secure. Try a different USB port.
  • Restart your computer.
  • Reinstall the data logger software if applicable.
  • Ensure the protective cap is fully removed before inserting into the USB port.
• Inaccurate Readings:
  • Ensure the sensor is not obstructed or exposed to extreme conditions outside its operating range.
