4. Operating Instructions

4.1 Starting a Recording Session

After configuring the data logger, disconnect it from the computer. To start recording:

• Press and hold the start button (usually the main button on the front) for approximately 5 seconds.
• A triangle sign will appear on the LCD screen, indicating that recording has successfully started.
• Place the data logger in the environment where temperature monitoring is required.

4.2 Stopping a Recording Session

The recording session will stop automatically based on the settings configured in the software (e.g., reaching maximum record points, specific stop time). You can also manually stop recording if the software settings allow for it, typically by pressing and holding the start button again for a few seconds until the triangle sign disappears or a stop indicator appears.

4.3 Viewing Current Data

The LCD screen on the RC-4 displays the current temperature reading. Short presses of the main button may cycle through other information such as maximum/minimum recorded temperatures or remaining battery life, depending on the model's firmware.

5. Data Management

5.1 Downloading Data

To download the recorded data:

1. Connect the RC-4 data logger to your computer using the USB cable.
2. Launch the Elitech data logger software.
3. The software should automatically detect the connected device and prompt you to download the data, or you may need to click a "View Data" or "Download" button within the application.

5.2 Viewing and Analyzing Data

Once the data is downloaded, the software will display it in various formats, including tables and graphs. You can analyze temperature trends, identify excursions, and review alarm events.

5.3 Exporting Reports

The Elitech software allows you to export the recorded data into various report formats for documentation and sharing.

Figure 4: The Elitech RC-4 supports exporting data reports into common formats such as PDF, Word, Excel, and plain text files, facilitating easy data sharing and analysis.

Common export formats include:

• PDF
• Microsoft Word (.doc/.docx)
• Microsoft Excel (.xls/.xlsx)
• Plain Text (.txt)

Note: When printing results, ensure you designate the specific data range or summary you wish to print to avoid printing every single reading, which can be extensive.

6. Maintenance

6.1 Cleaning

To maintain the device, wipe clean with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.

6.2 Battery Replacement

When the battery indicator on the LCD screen shows low power, replace the CR2450 battery. Open the battery compartment, remove the old battery, and insert a new CR2450 battery, ensuring correct polarity. Dispose of used batteries according to local regulations.
