5. Operating Instructions

5.1 Reading the LCD Display

The EL-USB-2-LCD features a clear LCD display that shows the current temperature and humidity readings. The display cycles between temperature (°C or °F) and relative humidity (%RH) at regular intervals. Alarm indicators (if configured) may also appear on the display.

5.2 Data Logging

Once configured and started, the logger will automatically record data at the specified sampling rate. The LED indicators will provide visual feedback on the logger's status (e.g., green for normal operation, red for alarms).

5.3 Downloading Data

To download recorded data:

1. Plug the EL-USB-2-LCD data logger back into your computer's USB port.
2. Open the EasyLog software.
3. The software will automatically detect the logger and prompt you to download the data.
4. Once downloaded, you can view the data in graphical or tabular format, export it to various file types (e.g., CSV, Excel), and generate reports.

5.4 Stopping a Logging Session

A logging session can be stopped via the EasyLog software when the device is connected to the computer, or if configured, by pressing a button on the device itself (if applicable to your model's settings).

6. Maintenance

6.1 Battery Replacement

The EL-USB-2-LCD uses a user-replaceable 1/2 AA 3.6 Volt Lithium Battery. The typical battery life is approximately one year, depending on usage and sampling rate. When the battery is low, the logger's LED may indicate this, and the software will also notify you.

To replace the battery:

1. Ensure the logger is not actively recording data and is disconnected from the computer.
2. Carefully open the battery compartment (refer to the device's physical design for access).
3. Remove the old battery and insert a new 1/2 AA 3.6 Volt Lithium Battery, observing correct polarity.
4. Securely close the battery compartment.

Warning:

• Use only the specified battery type.
• Dispose of old batteries responsibly according to local regulations.

6.2 Cleaning

Wipe the logger with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the USB port and sensor areas are kept clean and free of debris.
